Description

FIELD OF THE INVENTION

The present invention concerns a method for application of extensions and a device for realising the method. In particular, the invention relates to the hair styling/hairdressing sector for processing female and/or male hair styles.

BACKGROUND ART

The application of an extension is a cosmetic method for improving and emphasising a person's hairstyle; in particular is consists in an artificial integration of human hair.
Differently to wigs, extensions do not have the function of creating an artificial hairstyle on a person's head, but are use for thickening or lengthening hair that is already present. Extensions can be made with human hair or other hair constituted by synthetic fibres.
The effects of extensions are to simulate a type of hairstyle which normally could not be realised with a person's natural hair. As is known there exist various methods for a application of the extension.
A first method consists in applying, on a lock of natural hair of the person to be subjected to the treatment, an artificial preformed lock constituted by a predetermined number of natural and/or artificial hair. The artificial lock is grouped thanks to sewing or by application of clips.
The method comprises application of the extensions on natural hair by use of adhesive or biadhesive tapes. This method, firstly, has a purely aesthetic drawback, as the application of the adhesive/biadhesive tape is visible. In fact this makes application of the extensions on particularly exposed zones of the head, for example the top part of the head. Beyond this, the fact of having to use preformed extensions, constituted by a predetermined number of hairs, leads to a poor degree of freedom in application of the artificial hair and thus the impossibility of actually responding to and following the real density of the natural hair of the person to whom the extensions are being attached.
A second method consists in predisposing various locks of natural hair of the person to whom the extensions are to be applied and corresponding artificial preformed locks. The artificial lock is constituted by a predetermined number of natural hairs and/or constituted by synthetic fibres. In particular, this method comprises knotting the artificial lock of hair of the person to whom the locks are to be applied. The aesthetic result of this method is appreciable, but is extremely limited in terms of durability, in particular the knotting of the extensions exhibits poor durability over time.
A further method consists in fixing, on locks of natural hair, locks of artificial preformed hair constituted by a predetermined number of hairs, using connectors. In greater detail, the connector exhibits a tubular shape the external surface of which engages the artificial lock. The connector is arranged on an end of the artificial lock and enables maintaining the predetermined number of hairs joined in a single block. The method also consists in passing the lock of natural hair of the person to whom the extensions are to be applied internally of the connector up to arranging the connector in the desired position, which usually coincides with the attaching of the hair. Once the connector is positioned a pressure is performed thereon which crushes and blocks the connector, in particular the lock, on the person's hair.
As for the first described method, this method is also very aesthetically visible and thus exhibits considerable limitations relating in particular to the application zones. Beyond this, the described method exhibits a poor duration over time.
A further method consists in the predisposing of locks of natural hair of the person to whom the extensions and preformed artificial locks are to be applied, constituted by a predetermined number of natural hair and/or constituted by synthetic fibres. The predetermined number of hairs is maintained unitary by means of a predetermined quantity of solid glue. In particular, the artificial lock is maintained together by the glue at an end of the predetermined number of hairs. The glue is in the solid state with a V-shape, a tubular shape or flat.
Firstly the method comprises superposing the solid glue with an attaching portion of the lock of natural hair, which coincides with the attachment of the natural hair. Thereafter the lock of artificial hair and the lock of natural hair are pressed, tending to near them. Then the method comprises applying heat energy on the solid glue such as to enable a passage of state thereof. In particular, the application of energy enables the glue to pass from the solid state to the liquid state. In this way, by combining the joining pressure of the hair and the application of heat energy it is possible to bring the glue into contact with both the lock of natural hair of the person to whom the hair extension is to be applied and with the artificial hair. Then, by stopping the application of energy it is possible to solidify the glue which enables superposingly trapping the lock of natural hair of the person to whom the extensions are to be applied.
The methods used to enable passage of state of the glue include, for example, conduction of heat or alternatively use of ultrasounds.
Aesthetically the described method leads to good results, though the heat used on the glue can damage, in particular, split, the natural hairs.
Further, the present method is poorly flexible, as it obliges the professional to use predetermined standard modules of artificial locks of hair. Beyond the preceding limitations, the following application does not allow for total cohesion with the hairs of the person, but a simple superposing. Also, the superposing tends to increase, in an uncontrollable way (and sometimes visibly), the thickness of the hairs in proximity of the attachment. Although the mentioned process sometimes leads to good aesthetic results and good duration over time, the predetermined quantity of glue present on the module is visible and also leads to a considerable increase in heaviness of the hairs due to the weight thereof, much limiting the flexibility and freedom of intervention by the operator.

AIM OF THE INVENTION

The aim of the present invention is therefore to substantially obviate all the drawbacks and limits in the preceding solutions.
A first aim of the invention is to disclose an extremely flexible method which affords a professional total freedom of creativity regarding the hairstyle.
A further main aim of the invention is to disclose a method which does not damage the person's hair on whom treatment is performed.
A further aim of the invention is to disclose a method which enables obtaining an excellent aesthetic result, in particular making the artificial application of hair hardly visible.
A further aim of the invention is to disclose a method which enables obtaining an artificial application that is very resistant and therefore endures over time.
One or more of the above-described aims and which will more fully emerge during the course of the following description are substantially attained by a method and a device for application of extensions according to one or more of the accompanying claims.

DETAILED DESCRIPTION

The invention described in the following relates to a method for the application of extensions, which method can be applied both in private and in dedicated structures operating in the field of cosmetic treatments.
Extensions are of artificial integrations of human hair for thickening and/or lengthening the hair already present, in such a way as to obtain effects or hairstyles difficult to obtain with the subject's own hair. The extensions can be made with human hair or alternatively with synthetic fibres that are effectively able to emulate the natural hair of the people to whom the extensions are to be applied. The extensions are made of different lengths, thicknesses and colours so as to be able to make applications having an excellent aesthetic synergy on people having different types of hair.
In the course of this description reference is made to locks/artificial hairs to indicate the extensions to be applied to the real hair of the subject, which locks, as mentioned, can be either real or artificial hair.
The invention is a method for the application of extensions that comprises the use of glue for the integration of natural hairs. Before the description of the method, devices will be described in detail that are usable for carrying out the method. In particular, with reference to the accompanying figures, 11 denotes as a whole a dispenser configured such as to contain and dispense a predetermined quantity of glue 6 for connecting the artificial hair to natural hair of a person.
A first embodiment, shown in figure 1, illustrates a applicator 11 constituted by a container 17 made in a single piece which enables both containment (in particular the glue is directly inserted and in contact with the internal walls of the container) and distribution of the predetermined amount of glue 6. In greater detail, the structure of the container 17 can be said to internally afford a housing 18 having a predetermined volume V in which the glue is contained. The container 17 exhibits, but is not limited to, an elongate shape affording a good grip and easy use to the person applying. The container 17 non-limitingly exhibits an elongate cylindrical shape developing along an extension direction 19 delimited by a first and a second end 20a, 20b.
In further detail, the applicator 11 includes a main opening 24 which sets the housing compartment 18 fluid communication with the external environment and which enables the exit of the glue from the main opening 24. The main opening 24 is non-limitingly arranged, on an end of the container 17, in particular arranged at the first end 20a of the container. The main opening 24 extends along a parallel direction to the extension direction 19 of the container 17, in particular extending along the axis of revolution of the cylindrical body.
The container 17 comprises an intermediate portion 12 positioned between the first and second ends 20a, 20b, which enables a correct grip of the dispenser 1, and configured such as to allow the exiting of the glue. The applicator 11 enables the glue to exit following a variation, in particular a reduction, of the volume V of the housing compartment 18. The reduction in volume pushes the glue inside the housing compartment 18 to outside the main opening 24.
Going into further detail, a reduction of internal volume V can be achieved due to a compression of the container 17 by means of application of a thrusting force on the intermediate portion 12. The container 17, in the embodiment described above, exhibits an elastic structure enabling it to deform, at least at the intermediate portion 12, during the compression step, and subsequently to return to the original size after the thrust force has been removed.
As shown in figure 1, the applicator 11 includes a dispenser 37 arranged at the main opening 24. The dispenser 37 emerges from the container parallel to the extension direction 19 of the latter and has a substantially cylindrical elongate shape, in particular a conical shape tapering in distancing direction from the housing compartment 18. The dispenser 37 has a first end 37a arranged at the main opening 24 and a second end 37b opposite the first end 37a with respect to the dispenser 37. The dispenser comprises a through-cavity 38 which places the main opening 24 in fluid communication with the external environment. In particular, the through-cavity extends through the dispenser along the main development direction 19 of the container 17. The through-cavity 38 includes a first opening 38a in fluid communication with the main opening 24 and arranged at the first end 37a of the dispenser 37. The first opening 38a is in fluid communication with the main opening and has a passage section that is substantially equal to the passage section thereof. The through-cavity 38 further includes a second opening 38b is arranged substantially on the second end 37b of the dispenser 37. The second opening 38b is in fluid communication with the first opening 38a and consequently with the main opening 24. The second opening 38b exhibits a passage section that is lower than the passage section of the first opening 38a. The narrowing of the through-cavity, according to an exit direction of the glue from the jacket 32, enables the dispenser 37 to increase the sensitivity of the dispensing of the predetermined amount of glue 6 and increase precision of application on the hair.
A second embodiment includes an applicator 11 comprising a container 17 exhibiting a substantially elongate shape along an extension direction 19. In particular, the container 17 non-limitingly exhibits a tubular shape that internally defines a housing 18 having a predetermined volume V. The container 17 has a first and a second end 20a, 20b opposite one another and from which extend, respectively, an abutment portion 21 a and a pusher portion 21 b. These portions extend transversally, in particular perpendicularly, with respect to the extension direction of the container 17 and have an entering direction with respect to the housing compartment 18. In fact, the abutting portion, the pusher portion and the internal surface of the pipe delimit the housing compartment 18 of the container 17, thus constituting the volume V. in greater detail, the structure of the housing compartment 18 can be seen to have a substantially cylindrical shape.
Going into further detail, the container 17 comprises a first and a second element 22a, 22b mutually engaged with each other and reciprocally mobile. In the engaged condition, therefore, the first and second members 22a, 22b thus define the housing compartment 18. The first and second members 22a, 22b have respective engagement portions 23 which constrain the two elements and also enable the relative movement of the two. In particular, the first element 22a comprises a first engagement portion 23a which is connected to a second engaging portion 23b of the second element 22b. The first and the second engaging portion 23a, 23b include, non-limitingly, respectively a tapping and a threaded hole suitable for accommodating the tapping of the first element 22a (or vice versa). In fact, between the first and the second element the engagement portion 23 defines a movable coupling/constraint that enables a substantial relative rotation between the two elements.
The rotation of at least one of the elements leads to performing relative movements between the two elements along the extension direction 19 of the container 17, in particular to performing a series of axial movements along the extension direction 19. The relative axial displacement between the two elements enables varying the internal volume V of the housing compartment 18, characterized by a relative nearing between the first and second ends 20a, 20b, in particular an approach along the extension direction 19 of the container 17 of the abutment portion 21 a to the thrust portion 21 b.
The container 17 comprises, at least at an end thereof, in particular at the first end 20a, a main opening 24 which places the housing compartment 18 in fluid communication with the external environment and which enables dispensing the predetermined amount of glue 6 for the connection of the artificial hair. More specifically, the main opening 24 is arranged on the abutting portion 21 a of the container 17 and extends through the container 17 such as to define a through-opening, in particular extending parallel to the extension direction 19 of the container 17. In the accompanying drawings a preferred form of the main opening 24 is represented, which has a substantially circular shape arranged concentrically with respect to the extension direction 19 of the container 17 and which extends along the extension direction 19.
The container 17 further comprises a manoeuvring portion 25 configured such as to allow relative movement of the first and second element with a consequent reduction of the volume V of the housing compartment 18. As previously mentioned, the reduction in the volume of the housing compartment 18 enables glue to exit from the main opening 24. In more detail the manoeuvring portion 24 enables the first and second members 22a, 22b to be rotated relatively to one another, with a consequent relative axial sliding between the two.
As can be seen from figure 2, the manoeuvring portion 25 is arranged, non-limitingly, on said first element 22a (alternatively it the manoeuvring portion can be arranged on the second element 22b) and is constituted by a portion emerging radially from the first element 22a such as substantially to create a grip. In particular, as can be observed from the accompanying drawings, the manoeuvring portion 25 substantially comprises a disc having a greater diameter than the diameter of the first and/or the second element 22a, 22b. The disc has a given thickness which ensures a certain grippability thereon and facilitates the movement of the two elements.
As shown in the accompanying figures, it is possible to have, on the peripheral surface of the disc, a pickup element 26 configured to increase the friction on the manoeuvring portion 25 so as to facilitate handling of the two elements. More specifically, the gripping element 26 is constituted by a ring of plastic material and/or rubber coupled to the outer peripheral surface of the disc (figures 2 to 6).
Alternatively, the gripping portion 26 can be represented by a machining outer surface (not shown inside the accompanying drawings) borne on said first and/or second element and configured to increase the friction on the manoeuvring portion 25. For example the machined outer surface may be a knurling or the execution of a series of grooves or a machining able to increase the roughness of the outer portion of the manoeuvre relative to the surface not machined.
As can be seen from figures 3 to 6, the container 17 may include a grip portion 27 which emerges transversally from the container along a main development direction 28. The grip portion 27 is configured such as to afford a stable and secure grip of the container 17 and facilitate the relative movement between the first and the second mobile elements 22a, 22b. In particular, the gripping portion 27 is connected with the first and/or second element, and non-limitingly exhibits a substantially cylindrical shape.
As shown in the accompanying figures, the dispenser 1 can include at least a lighting device 29 configured such as to illuminate the area on which the glue is to be applied. In more detail, the light device, as seen in figures 4, 5 and 6, comprises a support 30 connected to the second element 22b (alternatively it is possible to connect the support 30 to the first element 22a) which enables coupling the lighting device 29 to the container. The support 30 is configured such as to support the light device itself and enable the light device to move along the extension direction 19 of the container 17 and/or rotate around the container 17 and/or vary its inclination with respect to the direction of extension 19 of the container 17. In further detail, the lighting device 29 can comprise a laser light and/or an LED and or the like. Still in relation to the second embodiment of the applicator 11, the applicator 11 also comprises a cartridge 31 arranged inside the housing compartment 18 and which constitutes the glue-containing element. The cartridge 31 has, but is not limited to, a substantially cylindrical elongate shape extending along a main development direction 31c. The container further comprises a jacket 32, defining a predetermined volume internally of the cartridge 31 suitable for containing the predetermined amount of glue 6. In particular, the cartridge 31 exhibits a first and a second end 31 a, 31 b and, on at least one thereof, the cartridge 31 affords a passage opening 34 which enables exit of the glue from the jacket 32.
To enable the glue to exit, the cartridge 31 comprises a piston 33 substantially complementarily shaped with respect to and arranged inside the jacket 32. The piston is slidingly mobile inside the jacket; in particular the piston 33 moves along the main development direction 31c of the cartridge 31. In more detail, the glue is arranged inside the jacket 32, in particular is interposed between the passage opening 34 and the piston 33. The movement of the piston 33 along the main development direction of the cartridge 31 c towards the opening of passage 34 pushes the glue through the passage opening 34.
As can be seen from the sectional view of figure 6, at least a sealing element 35, such as a gasket, can be applied on the external peripheral surface of the piston 33, such as to prevent leakage of adhesive through the external peripheral surface of the piston 33 and ensure optimum thrust of the glue out of the jacket 32 through the passage opening 34. As can be seen from figures 5 and 6, the cartridge 31 also comprises a thrust element 36 connected with the piston 33 and emerging from an end of the cartridge, in particular from the opposite end on which the passage opening 34 is disposed. The thrusting member 36 emerges from the cartridge 31 along the main development direction 31 c of the cartridge 31.
An analysis of engagement condition between the container 17 and the cartridge 31 (figure 6) leads to the observation that the main development direction 31c of the cartridge 31 is substantially parallel to the extension direction 19 of the container 17; in particular the directions substantially coincide. Still with reference to the engagement condition between the container 17 and the cartridge it can be observed that the end of the cartridge comprising the passage opening 34 is in contact with the abutting portion 21a of the first element 22a, while the thrust element 36, and in particular the end portion of the thrust element 36, is in contact with the thrust portion 21 b of the second element 22b.
In more detail, it can be observed that, in the engagement condition, the passage opening 34 of the cartridge 31 is located at the main opening of the container 17. As previously mentioned the activation of the manoeuvring portion 25 enables the abutment portions to be neared to the container 17. By doing this, the abutment portion acts as a stop for the cartridge 31 while the pusher portion moves the thrust element 36. The movement of the thrust element causes the piston to slide inside the jacket 32, with a consequent exiting of the glue from the passage opening.
In fact, the change in volume of the housing compartment 18, in particular the reduction of the volume, enables exit of the glue from the passage opening which, being arranged in correspondence of the main opening 24, enables the glue to exit therefrom.
Still in relation to the second embodiment, the cartridge 31 can comprise a dispenser 37 arranged at the passage opening 34. The dispenser 37 emerges from the cartridge 31 parallel to the extension direction 31 c thereof and exhibits a substantially cylindrical elongate shape, in particular a conical shape tapering distancingly from the housing compartment 18. The dispenser 37 exhibits a first end 37a arranged at the passage opening 34 and a second end 37b opposite the first end 37a with respect to the dispenser 37. The dispenser 37 comprises a through-cavity 38 which places the passage opening 34 in fluid communication with the external environment. In particular, the through-cavity 38 extends through the dispenser along the main development direction 19 of the container 17. The through-cavity 38 comprises a first opening 38th in fluid communication with the passage opening 34 and arranged on the first end 37a of the dispenser 37. The first opening 38a is in fluid communication with the passage opening 34 and has a passage section substantially equal to the passage section of the passage opening 34. The through-cavity 38 further includes a second opening 38b is arranged substantially on the second end 37b of the dispenser 37. The second opening 38b is in fluid communication with the first opening 38a and consequently with the passage opening 34. The second opening 38b exhibits a passage section that is smaller than the passage section of the first opening 38a. The narrowing of the through-cavity, in an exiting direction of the glue from the jacket 32, enables the dispenser 37 to increase the dispensing sensitivity of the predetermined amounts of glue 6 and increase the precision of application on the hair.
As shown in figures 7 and 8, with 39 is indicated as a whole a dispenser configured to carry a plurality of hair 40 and allow the release of the latter in a condition of extraction which is characterized by the application of a pulling force on the hair 40 adapted to release the latter from the same dispenser.
In more detail, the dispenser 39 includes a first and a second gripping portion 41, 42 engaged to one another. The plurality of hairs 40 is interposed between the first and second gripping portions 41, 42 which are configured such as to exert a closing force on the hair 40. The first and second gripping portions 41, 42 exhibit, at the respective sides facing one another, a plurality of elements 69 emerging projectingly and destined to interfere with the hairs interposed between the grip portions. In a preferred embodiment, the first and the second gripping portions 41, 42 are both hooked strips of Velcro. By arranging two strips of Velcro of the same sort (hooks) facing one another to close the plurality of hair 40, the hair between the emerging elements can be trapped without creating an excessive clamping force, which could damage the hairs during the extraction phase thereof. Alternatively, instead of the Velcro strips simple strips of cloth can be used. The dispenser 39 further comprises a blocking element 70 configured such as to couple for example the first and second gripping portions 41, 42 and enable, by means of the emerging elements 69, the desired retaining of the plurality of hairs 40. In a preferred but non-limiting embodiment, the blocking element 70 comprises a sew part at least on the edge from which the plurality of hairs 40 emerges.
The dispenser can further comprise a covering element 71 (figure 9) arranged externally of the first and/or second gripping portion 41, 42. The covering element 71 is configured such as at least partially to cover the first and/or second gripping portion 41, 42. The covering element 71 includes, but is not limited to, a strip of cloth. The longitudinal ends are tightly coupled (for example, are sewn) together by means of the blocking element 70. Further, the seam (or the blocking element) might interest only the longitudinal edges of the covering element 71 and not the gripping portions 41, 42.
As can be seen from figures 7 and 8, the dispenser 39 includes a support structure 43 destined to engage the first and/or second gripping portion 41, 42 and enable the hair, engaged inside the gripping portions, to be arranged in an extension condition which facilitates the grip of the hairs. In greater detail, the support structure 43 comprises a support base 44 and at least a frame 45. The base plate 44 is, non-limitingly, a plate configured such as to provide a stable support for the frame 45. With regard to the frame 45, it exhibits a lower end 45a connected to the base plate 44 and an upper end 45b arranged on the opposite side with respect to the lower end 45a. In particular, the frame 45 extends transversally, in particular perpendicularly, with respect to the base 44, thereby defining a distance between the upper end 45b of the frame 45 and the base 44. The upper end 45b engages the first and/or the second gripping portion 41, 42 bringing it or them to a height equal to the distance between the base and the upper end 45b. In this way the frame 45 enables arranging the hairs inside the gripping portions in an extension condition which facilitates gripping and extraction of the hairs of the person to whom the extension is to be applied.
In a preferred embodiment, the frame 45 is configured such as to enable a variation of the distance between the upper end 45b and the support base 44, in particular to enable the arrangement of the gripping portions engaged with the upper end of the frame to be arranged in at least two, in particular in a plurality of different vertical positions. More in detail, the frame 45 comprises a fixed part 46 comprising the support base and a guide 47 and a mobile part 48 comprising a supporting portion 49 which engages the first and/or second gripping portion and a guide 50 destined to abut the guide 47 of the fixed part 46. The mobile part 48 slides with respect to the fixed part along the guides. The movement of the mobile part 48 enables the hair to be engaged at different heights inside the gripping portions.
As shown in the accompanying figures, it can be observed that the guide 47 of the fixed part includes, but is not limited to, two tubes which extend transversally, in particular perpendicularly, with respect to the support base 44. As regards, instead, the guide 50 of the mobile part 48, the mobile part 48 non-limitingly includes two tubes engaged internally to the tubes of the fixed part. The guide 50 of the mobile part can slide in the guide 47 of the fixed part 46 along the development direction of the frame.
In addition to the above-mentioned devices, the method for application of the extensions also includes the use of a rubbing element 51 configured such as to enable a correct joining between the artificial hair 40 and the natural hair. In particular, the rubbing element is used after the application of predetermined amounts of glue 6 on the hair such as to allow proper penetration of the glue between the artificial and natural hair.
The rubbing element 51 comprises a sheet having a rubbing surface suitable for contacting the hair and configured to slide on the hair.
The sheet can be constituted by at least one of the following materials: paper, plastic, synthetic or artificial fibres. As can be seen in figure 11 a plurality of sheets can be supplied in a container 52 from which the sheets can be extracted. The container 52 includes an attachment portion configured to allow the container 52 to be positioned on the actual person performing the application of the extensions, in particular wherein the attachment portion substantially comprises a bracelet abutting on the wrist and/or forearm of the person applying the extensions. A description will now be made of the method for application of the extensions, which is the same both for application of extensions made of synthetic fibres and natural hairs.
The method comprises a step of preparing a plurality of artificial hairs, non-limitingly, substantially equal to the number of natural hairs of the person to whom the extension is to be applied. Each artificial hair comprises at least a free end 4, which during the step of providing the plurality of hairs is substantially aligned to the free end of every other artificial hair.
To facilitate gripping of the artificial hairs, they can be arranged on the dispenser 39 between the first and second gripping portion 41, 42, and in particular the free ends 4 of the artificial hair can be engaged to the first and second gripping portion. As previously described, the dispenser 39 allows height-adjustment of the artificial hair inserted between the portions thereof. In this way the artificial hair can be arranged at a perfect height for facilitating gripping thereof to the person performing the application of the extensions.
The method also includes preparation of a predetermined number of natural hairs 2 of the person to whom the extension is to be applied. In particular, in this step includes grouping the predetermined number of hairs 2 of the person up until a substantial lock of hair 9 is formed. The grouping step consists essentially in separating the predetermined number of hairs 2 from the rest of the subject's hair.
To keep the predetermined number of hairs of the person spaced out, a separation element 10 can be used around the predetermined number of hairs. The separation element 10 is arranged substantially close to the skin and is configured such as to space, at least in the vicinity of separation element 10, the predetermined number of hairs 2 from the remaining hair of the person the extensions are to be applied to. The separation element 10 comprises a body 13 which extends substantially along a main development plane and which has, non-limitingly, a small thickness. The body 13 exhibits a through-seating 14 which enables passage through the body of the predetermined number of hairs 2. The extension of the body 13 along the main development plane enables the separation of the portion of the predetermined number of hairs 2 in the vicinity of the through-seating 14 from the remaining hair.
As can be seen in figures 9 and 10, the separating element 10 has a discoidal shape having a considerably smaller thickness than the radial extension of the disc. Alternatively, the separation element 10 can have a polyhedral shape having a dimension that is substantially smaller than the other two. The dimensions and material of the separation element 10 are such that it is very light in order that the lock of hair 9, passing through the through-seating 14, can support the separating member 10 and keep it in the predetermined position. In particular, the separation element 10, as shown in figure 9, is disposed substantially near the hairline which represents the application area of the extensions.
Once the preparation of artificial hair on the dispenser 39 has been carried out, and the grouping of the predetermined number of hairs 2 has been made, a lock 3 can be taken from the dispenser 39, the lock 3 being formed by a plurality of artificial hairs 3a that are at this point completely separated from one another and held exclusively in the professional's hand before applying. The lock 3 exhibits an end portion 5 consisting of the free ends 4 of the hairs. Subsequently, the lock 3, in particular the end portion 5 of the lock 3, is arranged on an attachment portion 7 of the predetermined number of hairs 2, which is located near the hairline of the person. The arrangement of the end portion 5 of the lock 3 on the attachment portion 7 of the predetermined number of hairs 2 defines an interposing zone 8.
Since the hairs to be applied are not constrained at the respective ends, on the one hand the desired amount thereof can be collected, while on the other hand, a very close mixing with the real hair of the subject can be performed, such as to drastically improve the aesthetic result as well as the tight coupling of the locks and hairs.
When the lock has been connected to with the predetermined number of hairs the fastening can be performed by providing, in the interposing area 8, a predetermined amount of glue 6. The glue is arranged with the above-described applicator 11 (a step shown schematically in figure 10). The step of applying the glue is done with no supply of thermal energy to the glue. More specifically, the glue inside the dispenser is in the liquid state, in particular the state of the glue enables performing at least the application step at a constant temperature and environment. During the application the glue, as mentioned, is in the liquid state and therefore able to penetrate within the interposing region 8 and contact both the predetermined number of hairs 2 and the lock 3.
Following the step of application of the predetermined amount of glue 6 is possible to perform a step of processing further configured to facilitate contact of the predetermined amount of glue 6 with the predetermined number of hairs 2 and the lock 3 while also enabling a perfect synergy between them. The processing step in particular consists substantially in gripping the interposing area 8 of the hair and imparting thereon a pressure in the interposing area 8 thereof. The pressure exerted allows expansion and penetration of the glue into the entire interposing area 8. The processing phase can further comprise a step of moving the interposing area 8 thereof. More simply, moving the interposing zone 8 substantially consists in a back and forth rubbing motion which also enables the hair to mingle and possibly become closely intertwined. In this way the thickness of the visible glue in the interposing area 8 can be reduced to a minimum thus the aesthetic appearance of the extensions can be improved. In particular, the total thickness of the extension attachment line can be minimised. The thickness can be quantified by the relationship between the final thickness of the extensions, given by the thickness of the interposing zone 8 and by the predetermined quantity of glue 6, and the thickness only of the interposing zone 8.
Following the application step and possibly the rubbing step, the glue passes rapidly from a liquid to a solid state so as to achieve the stable connection between the lock and the predetermined number of hairs. In more detail, the solidification of the glue traps the lock of hair on the hair, substantially creating a single body. The solidification step essentially comprises a polymerisation process, in particular a stepped polymerisation, of the glue. The glue used is, by way of non-limiting example, substantially a chemical compound comprising a cyanoacrylate ethylene and methacrylate. In particular, the level percentage of the two compounds in the glue can be quantified.
Quantitatively, the adhesive comprises at least 85% of ethylene cyanoacrylate, more particularly comprising an amount of ethylene cyanoacrylate higher than 90%, even more in particular comprising an amount of ethylene cyanoacrylate higher than 95%. As regards the methacrylate, the adhesive comprises at least 0.1 % of methacrylate, more particularly comprising an amount of methacrylate greater than 5%, even more in particular comprising an amount of methacrylate greater than 9%. Alternatively different types of glue can be used, provided that they are configured so as to ensure proper cohesion of the hair and enable a long-lasting cohesion.
The method described above has numerous advantages. In particular, cohesion by means of a liquid glue without any application of thermal energy enables maintenance of healthy hair, without inducing any split ends. In addition to this, the fact of being able to collect a predetermined number hairs from the dispenser 39 allows the person who intends to perform the application of extensions a greater flexibility and freedom during the creation of the hairstyle. In fact, the person who performs the hairstyle can choose the size and thickness of the lock to be installed. More precisely, the hairdresser can choose the number of hairs to be installed without having to adapt to the application of preformed extensions. This makes possible applications in highly-visible areas. The method described also enables creation an interposing zone 8 of very small thickness, which enables the extension to have a great visual impact.
