Definitions
- the invention relates to a hair extension and a fastening method for extending hair. Both serve to achieve an invisible attachment of a hairpiece, in particular to the head hair of the person.
- the invention relates to the attachment of such hair extensions in the professional hairdressing sector.
- hair extension predominantly hair strands, human hair or synthetic hair. This is attached to the head hair of the person, so that their own hair appears longer or fuller.
- different hair extensions and fastening methods are known.
- the hair strands can be connected by heat with the own hair.
- the incorporated individual hairs are connected at their tips by keratin, thermoplastic resin or other heat-reactive material to one strand of hair.
- These strands are then fixed by means of a heat tongs or staple, which can give off pressure and heat at the same time on the own hair.
- Such a hair extension and the associated fastening method together with the necessary tools are in the EP 98 830 205 A1 described.
- This method involves applying a certain amount of a liquid thermoplastic resin to the tips of a hair bundle. When the hair tips come in contact with the resin, they are compressed between a concave surface and a corresponding convex surface and then demolded again, so that they subsequently form a fingernail-like, concave support member. This concave area solidifies as the resin cools.
- the ES 2237331 A1 describes such a mechanical method, as well as the necessary aids for fixing the hair extensions.
- the kit in question includes an element through which the hair tress is pulled, on which the hair extension tress is to be applied. Further, the set includes annular elements for attachment to the type of washers. These are very flexible and durable. Finally, the hair extension set includes a forceps-type pressure-generating tool, as well as extension hair strands.
- the technique for fixing the hair extension works as follows: First, the area in which the hair extension is to be attached, exposed and any residues removed. Then the own hair strand on which the hair extension is to be attached, selected. This is then pushed through the ring, so that the disc-like element is just above the hair roots. The forceps is pushed in the opened state with a cheek under the selected own strand of hair in such a way that the pressure point lies under the drawn by the strand ring. Then the hair extension strand is inserted through the ring.
- the ES 1048116 U describes a hair extension made by a woven band. It is an oval band with a woven edge, on which hair of real hair are sewn.
- the hem of the band consists of a closed contour that separates two opposing parts. On one of the parts by weaving a hair clip attached, then the hair extension strand is attached.
- the ES 1056533 U describes a hair extension which is in the form of a hair bundle, or a hair pot, at one end of a fastener is provided by which the hair piece is attached to the natural hair of the user.
- the method described in the utility model is characterized in that a further hair bundle can be added, which protrudes at the end on which the fastening element is integrated. This extra hair piece can be knotted over the own hair, ideally over the upper part of the hair extension.
- the ES 1064500 U describes a hair extension by a method that is characterized in that a part are woven on the hair, is attached to the human hair. This is done by means of a series of small hollow cylinders, which are mounted on the inside of a fastening zone and in which the hair is then integrated. At the same time there are removable elements for threading in these cylinders.
- hair extension techniques in which the hairs are attached mechanically, but by heat.
- An example of this type of hair extension can be found in the international patent application PCT / ES 1996/00189 , There, a technique is described in which the hair extension strand is knotted with a strand of the own hair. The knot is protected by a tube, which has the property to contract when exposed to heat. The tube is attached by means of a specially developed apparatus.
- a disadvantage of the above-mentioned methods is that when applying hair extensions by means of heat, the use of a pair of pliers or a jaw is necessary. Because only by the aid of such tools sufficient pressure and heat is provided so that the heat-sensitive product is melted and thus the attachment of the hair extension is achieved to the own hair.
- the use of the heat tongs is associated with additional costs and requires a corresponding experience and expertise on the part of who, the Attaching the hair extensions performs because it simultaneously edit the human hair, attach the hair extension and must be able to operate the devices.
- the hair extension by heat therefore requires experience and knowledge to process the products with the heat tongs just until the melting point is reached, without the hair or the hair extension would be scorched.
- Another disadvantage of the heat technology is that even by looking only the place can be identified, where the hair has been connected to the hair extension, namely where the head hair is in the welded material.
- Thermal hair extension methods are easier to use. However, the combination of own hair and strand of foreign hair is much more sensitive. This leads to a shorter shelf life of the hair extensions. As a result, it must be removed and renewed in a shorter time compared to the other methods. In addition, the bonding site is partially visible and thus also to see that the respective person wears hair extensions.
- the known methods have the disadvantage that the compound is either not solid and durable enough or that the glued strands can not be released from the hair, whether to be cut off.
- the strands are attached to human hair, they gradually grow out of the invisible area and must be refastened, with the original bond typically no longer usable so that either the strand can no longer be used or shortened would have to, but mostly not desired.
- the object of the invention is therefore a method for hair extension to create, on the one hand simplifies the attachment of the hair extensions to the human hair and on the other hand creates a most inconspicuous connection.
- Another object of the invention is to provide a re-releasable, but for the period of wear to the growth of the junction of the human hair area solid connection with the human hair.
- the invention relates generally to hair extensions, which are meant to represent a plurality of hair, which are bundled at one end. This end is attached to the user's own hair.
- the bundled end of the hair extension strand forms a flexible, in particular made of plastic carrier element, by which the individual foreign hairs are united.
- the individual foreign hairs are attached by a permanently adherent adhesive to at least one side of the support element.
- the hair extension strand has a flattened surface shape at the bundled end.
- the permanently adhering adhesive comprises a polyurethane, preferably an elastomeric polyurethane.
- the adhesive comprises polyurethane based on a biogenic polyol, preferably based on vegetable oil, for example castor oil, rapeseed oil, soybean oil, sunflower oil and / or lingin.
- the carrier element contains a polyurethane or consists thereof, preferably an elastomeric polyurethane.
- the adhesive comprises polyurethane based on a biogenic polyol, preferably based on vegetable oil, for example castor oil, rapeseed oil, soybean oil, sunflower oil and / or lingin.
- the support element may be rectangular, round or oval.
- the carrier element has the above-mentioned adhesive on both sides.
- the Hair extension on both sides hair on.
- the carrier element is thinner than the adhesive layer which is applied to the carrier element on one side or on both sides.
- the material of the carrier element is equal to the material of the adhesive, so that preferably after fixing the hair on the carrier element, the carrier element and the adhesive are no longer distinguishable, particularly preferably are material-bonded.
- the carrier element consists of the material of the adhesive and in particular permanently bonds or mixes with it.
- the hair extension consists exclusively of the hair, the carrier element and the adhesive.
- the only holding element of the inventive Haarverinrungssträhne represents the flexible support member, on the surface of the foreign hair adhere.
- This flexible support element which bundles the individual foreign hair into a strand and at the same time represents the element to which the hair extension is finally attached to the human hair, can be varied in length or more or less shortened, depending on how thick or wide the strand of foreign hair should fail.
- the longitudinal sides of the rectangle of the carrier element shape can be adapted to the individual needs by the longitudinal sides are extended in order to glue more hair side by side on the inside of the support member can.
- One of the embodiments of the proposed invention is that attached to the flexible support member in the form of extended broad sides strip-shaped reinforced threads, which serve to extend the support member preferably further in the longitudinal direction.
- the threads act in particular as a reinforcement, so that the elongate support member on which the hair is fixed, does not tear. Furthermore, it is provided in one embodiment that the threads extend beyond the carrier element and, for example, can be combined or connected with a further hair extension.
- the method for attaching the hair extension to the own hair is the subject of this invention.
- the attachment is carried out as follows:
- a portion of the hair or a strand of the hair extension carrier is discarded such that the selected inner side of the hair is exposed.
- an adhesive based on cyanoacrylate alkyl cyanoacrylate
- the surface covered with adhesive is pressed against the inside of the selected hair part or hair strand of the head hair to attach the hair extensions to the own hair by the action of the adhesive.
- the adhesive Because of its ability to anionically polymerize, the adhesive has the property of polymerizing even at a low concentration of hydroxide ions, which is usually already present in the air humidity. Therefore, it is easily processable, as long as it is kept away from the order of humidity.
- This method of attachment has several significant advantages over current hair extension methods.
- the attachment of the foreign hair to the own hair works without the aid of tools. Furthermore, the hair extensions can then be removed if the wearer so desires.
- a solvent suitable for to remove the adhesive Preferably, to dissolve the cyanoacrylate (alkyl cyanoacrylate) based adhesive, a solvent comprising acetone and / or butanone, preferably 2-butanone, is used. Further preferably, the solvent is chosen such that it does not dissolve the adhesive which secures the foreign hair to the carrier element, more preferably the solvent is chosen such that this polyurethane does not dissolve. This method is very gentle and therefore also allows the reuse of the hair extensions, since the cyanoacrylate-based adhesive is completely detachable from the hair extension or from the holding element.
- Another advantage of the fixing method according to the invention is that the attachment of foreign hair to the own hairs needs no further connection elements, but the hair extensions are directly connected to the own hair and that on the inside of the own hair, that is, the side of the own hairs, which face the scalp when they hang down due to gravity. As a result, the point of attachment of the hair extension is hidden by the own hair itself.
- Fig. 1 a hair extension according to the invention in the form of a single strand from a frontal perspective
- FIG. 2 the hair extension out FIG. 1 in a side view
- FIG. 3 the hair extension out FIG. 1 in a further side view

- FIG. 5-7 schematically the individual steps of the invention Fixing method of hair extensions.
- the hair extension 1 has a flexible support element 11 made of plastic, which serves as a carrier of the hair extension strand 1 and on which the provided hair tips 12 of the hair extension 1 are attached.
- these hair tips 12 are placed on one of the sides of the flexible support member 11 and fixed by means of a - not shown - permanent adhesive to the flexible support member 11.
- the flexible support member 11 has a small format, since only a single strand of hair 12 is attached here.
- the flexible support member 11 an elongated shape.
- This may, for example, be in the form of a continuous band to which a hair layer formed by adjacent and / or superposed strands 12 is attached lengthwise.
- the flexible support member 11 is fiber-reinforced and in particular longitudinally crossed by reinforcing fibers 13. These reinforcing fibers 13 do not affect the flexibility of the support member 11, but are helpful because of the greater length of the support member to give the extended support member 11, the necessary stability and so can increase the width.
- a strand or a hair row 21 of the hair 2 of the person 21 is discarded, wherein the inner surface 22 of the Streak or hair row 21 is exposed.
- a gluing-based adhesive 3 based on cyanoacrylate is applied to the portion of the hair extension 1 connected to the supporting flexible support member 11.

Abstract
Description
Die Erfindung betrifft eine Haarverlängerung und ein Befestigungsverfahren zum Verlängern von Haaren. Beides dient dazu, eine unsichtbare Befestigung eines Haarteils, insbesondere an dem Kopfhaar der Person zu erreichen. Insbesondere betrifft die Erfindung die Anbringung derartiger Haarverlängerungen im professionellen Friseurbereich.The invention relates to a hair extension and a fastening method for extending hair. Both serve to achieve an invisible attachment of a hairpiece, in particular to the head hair of the person. In particular, the invention relates to the attachment of such hair extensions in the professional hairdressing sector.
Derzeit ist es allgemein bekannt, zur Haarverlängerung überwiegend Haarsträhnen, Echthaar oder Kunsthaar zu verwenden. Dies wird an dem Kopfhaar der Person befestigt, damit um deren Eigenhaar länger oder fülliger erscheint. In diesem Zusammenhang sind unterschiedliche Haarverlängerungen und Befestigungsverfahren bekannt.Currently, it is generally known to use for hair extension predominantly hair strands, human hair or synthetic hair. This is attached to the head hair of the person, so that their own hair appears longer or fuller. In this connection, different hair extensions and fastening methods are known.
Bei Haarverlängerungen können die Haarsträhnen durch Hitze mit dem Eigenhaar verbunden werden. Hierbei werden die einzuarbeitenden einzelnen Haare an ihren Spitzen durch Keratin, thermoplastischen Kunstharz oder einen anderen hitzereaktiven Stoff zu jeweils einer Haarsträhne verbunden. Diese Strähnen werden dann mittels einer Wärmezange oder Klammer, die gleichzeitig Druck und Hitze abgeben kann, am Eigenhaar fixiert.In hair extensions, the hair strands can be connected by heat with the own hair. Here, the incorporated individual hairs are connected at their tips by keratin, thermoplastic resin or other heat-reactive material to one strand of hair. These strands are then fixed by means of a heat tongs or staple, which can give off pressure and heat at the same time on the own hair.
Eine solche Haarverlängerung und das zugehörige Befestigungsverfahren zusammen mit den notwendigen Werkzeugen sind in der
In der internationalen Patentanmeldung
Es sind mechanische Haarverlängerungsmethoden bekannt, bei denen mittels mechanischer Halteelemente Strähnen an das Eigenhaar befestigt werden. Dazu eignen sich zum Beispiel Ringe, Clips, Fäden, Klammern, Thermo-Schrumpfschläuche oder ähnliche Befestigungselemente. Die
Die Technik zur Befestigung der Haarverlängerung funktioniert wie folgt: Zunächst wird der Bereich in dem die Haarverlängerung angebracht werden soll, freigelegt und eventuelle Rückstände entfernt. Sodann wird die Eigenhaarsträhne, auf der die Haarverlängerung angebracht werden soll, ausgesucht. Diese wird dann durch den Ring geschoben, sodass das scheibenartige Element kurz über den Haarwurzeln liegt. Die Zange wird in geöffnetem Zustand mit einer Backe unter die ausgesuchte Eigenhaarsträhne geschoben und zwar so, dass der Druckpunkt unter dem durch die Strähne gezogenen Ring liegt. Daraufhin wird die Haarverlängerungssträhne durch den Ring eingeführt. Mit dem anderen Ende der Zange wird nun auf den Ring gedrückt, durch welchen sowohl die Echthaarsträhne als auch die Fremdhaarsträhne eingeführt worden sind, und die Unterbelegscheibe mitsamt Haarverlängerung so an der Eigenhaarsträhne befestigt. Falls ein Teil der Haarverlängerungssträhne des zusammengedrückten Ringes überhängen sollte, ist der Teil abzuschneiden.The technique for fixing the hair extension works as follows: First, the area in which the hair extension is to be attached, exposed and any residues removed. Then the own hair strand on which the hair extension is to be attached, selected. This is then pushed through the ring, so that the disc-like element is just above the hair roots. The forceps is pushed in the opened state with a cheek under the selected own strand of hair in such a way that the pressure point lies under the drawn by the strand ring. Then the hair extension strand is inserted through the ring. With the other end of the forceps is now pressed onto the ring through which both the human hair strand and the Fremdhaarsträhne have been introduced, and the Unterbelegscheibe together with hair extension so on the Self-hair strand attached. If any part of the hair extension strand of the compressed ring overhangs, the part should be cut off.

Es gibt auch Haarverlängerungstechniken, bei denen die Haare zwar auf mechanische Weise befestigt werden, dies jedoch mittels Hitzeeinwirkung. Ein Beispiel für diese Art der Haarverlängerung findet sich in der internationalen Patentanmeldung
Schließlich sind auch selbstklebende Verfahren der Haarverlängerung bekannt, bei denen doppelseitige Klebebänder zur Befestigung verwendet werden. Auf der einen Seite werden die Haarverlängerungen angebracht, während auf der anderen Seite die Klebefolie an dem Echthaar befestigt wird. Die
Ein Nachteil der oben erwähnten Verfahren besteht darin, dass beim Anbringen von Haarverlängerungen mittels Wärmeeinwirkung die Verwendung einer Zange oder einer Klemmbacke Notwendig ist. Denn nur durch die Zuhilfenahme solcher Werkzeuge wird genügend Druck und Wärme bereit gestellt, damit das wärmeempfindliche Produkt zum Schmelzen gebracht und somit die Befestigung der Haarverlängerung an das Eigenhaar erreicht wird. Der Gebrauch der Wärmezangen ist allerdings mit zusätzlichen Kosten verbunden und erfordert eine entsprechende Erfahrung und Fachkenntnis auf Seiten desjenigen, der die Befestigung der Haarverlängerungen durchführt, da er gleichzeitig das Echthaar bearbeiten, die Haarverlängerung anbringen und die Geräte bedienen können muss. Die Haarverlängerung mittels Wärme erfordert daher Erfahrung und Kenntnis, um die Produkte mit der Wärmezange gerade so lange zu bearbeiten, bis der Schmelzpunkt erreicht ist, ohne dass dabei das Eigenhaar oder die Haarverlängerung versengt würde.A disadvantage of the above-mentioned methods is that when applying hair extensions by means of heat, the use of a pair of pliers or a jaw is necessary. Because only by the aid of such tools sufficient pressure and heat is provided so that the heat-sensitive product is melted and thus the attachment of the hair extension is achieved to the own hair. The use of the heat tongs, however, is associated with additional costs and requires a corresponding experience and expertise on the part of who, the Attaching the hair extensions performs because it simultaneously edit the human hair, attach the hair extension and must be able to operate the devices. The hair extension by heat therefore requires experience and knowledge to process the products with the heat tongs just until the melting point is reached, without the hair or the hair extension would be scorched.
Ein weiterer Nachteil der Wärmetechnik ist, dass bereits durch bloßes Hinsehen die Stelle ausgemacht werden kann, an denen das Eigenhaar mit der Haarverlängerung verbunden worden ist, nämlich dort wo das Kopfhaar in dem eingeschweißten Material steckt.Another disadvantage of the heat technology is that even by looking only the place can be identified, where the hair has been connected to the hair extension, namely where the head hair is in the welded material.
Die Anbringung von Haarverlängerungen mittels mechanischer Befestigungen wiederum erweist sich als vergleichsweise langsam und aufwendig und birgt zudem den Nachteil, dass die Ringe, Metallhülsen, Clips oder andere Befestigungselemente ebenfalls sichtbar sind und beim Liegen oder Tragen von Kopfbedeckungen unangenehm drücken.The attachment of hair extensions by means of mechanical fasteners in turn proves to be relatively slow and expensive and also has the disadvantage that the rings, metal sleeves, clips or other fasteners are also visible and uncomfortable when lying or wearing headgear.
Thermische Haarverlängerungsmethoden erweisen sich dagegen als einfacher in der Anwendung. Allerdings ist die Verbindung von Eigenhaar und Fremdhaarsträhne wesentlich empfindlicher. Dies führt zu einer kürzeren Haltbarkeitsdauer der Haarverlängerungen. Folglich muss sie im Vergleich zu den anderen Verfahren in kürzerer Zeit entfernt und erneuert werden. Zudem ist auch hier die Bonding-Stelle teilweise zu sehen und damit auch zu sehen, dass die jeweilige Person Haarverlängerungen trägt.Thermal hair extension methods, on the other hand, are easier to use. However, the combination of own hair and strand of foreign hair is much more sensitive. This leads to a shorter shelf life of the hair extensions. As a result, it must be removed and renewed in a shorter time compared to the other methods. In addition, the bonding site is partially visible and thus also to see that the respective person wears hair extensions.
Schließlich haben die bekannten Verfahren den Nachteil, dass die Verbindung entweder nicht fest und dauerhaft genug ist oder dass die eingeklebten Strähnen nicht mehr aus dem Haar gelöst werden können, ob abgeschnitten zu werden. Da die Strähnen jedoch an Echthaar befestigt werden, wachsen sie mit der Zeit aus dem unsichtbaren Bereich heraus und müssen erneut befestigt werden, wobei die ursprüngliche Verbindung in der Regel nicht mehr verwendet werden kann, so dass entweder die Strähne nicht mehr benutzt werden kann oder gekürzt werden müsste, was aber meist nicht gewünscht ist.Finally, the known methods have the disadvantage that the compound is either not solid and durable enough or that the glued strands can not be released from the hair, whether to be cut off. However, because the strands are attached to human hair, they gradually grow out of the invisible area and must be refastened, with the original bond typically no longer usable so that either the strand can no longer be used or shortened would have to, but mostly not desired.
Aufgabe der Erfindung ist es daher, ein Verfahren zur Haarverlängerung zu schaffen, das einerseits das Befestigen der Haarverlängerungen an das Echthaar vereinfacht und andererseits eine möglichst unauffällige Verbindung schafft. Eine weitere Aufgabe der Erfindung besteht darin, eine wiederlösbare, aber für die Tragedauer bis zum Herauswachsen der Verbindungsstelle aus dem Echthaarbereich feste Verbindung mit dem Echthaar zu schaffen.The object of the invention is therefore a method for hair extension to create, on the one hand simplifies the attachment of the hair extensions to the human hair and on the other hand creates a most inconspicuous connection. Another object of the invention is to provide a re-releasable, but for the period of wear to the growth of the junction of the human hair area solid connection with the human hair.
Diese Aufgabe wird nach der Erfindung durch Haarverlängerungen nach Anspruch 1 und ein Verfahren nach Anspruch 5 sowie ein Haarverlängerungsset nach Anspruch 6 gelöst.This object is achieved according to the invention by hair extensions according to
Die Erfindung betrifft allgemein Haarverlängerungen unter denen gegenständlich eine Vielzahl von Haaren zu verstehen ist, die an einem Ende gebündelt sind. Dieses Ende wird an dem Eigenhaar des Benutzers befestigt. Das gebündelte Ende der Haarverlängerungssträhne bildet ein biegsames, insbesondere aus Kunststoff bestehendes Trägerelement, durch welches die einzelnen Fremdhaare vereint sind. Die einzelnen Fremdhaare werden durch ein permanent haftendes Klebemittel an zumindest einer Seite des Trägerelements angebracht. Vorzugsweise weist dabei die Haarverlängerungssträhne an dem gebündelten Ende eine abgeflachte Oberflächenform auf.The invention relates generally to hair extensions, which are meant to represent a plurality of hair, which are bundled at one end. This end is attached to the user's own hair. The bundled end of the hair extension strand forms a flexible, in particular made of plastic carrier element, by which the individual foreign hairs are united. The individual foreign hairs are attached by a permanently adherent adhesive to at least one side of the support element. Preferably, the hair extension strand has a flattened surface shape at the bundled end.
In einer bevorzugten Ausgestaltung enthält der permanent haftende Klebstoff ein Polyurethan auf, vorzugsweise ein elastomeres Polyurethan. Weiterhin bevorzugt umfasst das Klebemittel Polyurethan auf Basis eines biogenen Polyol, bevorzugt auf der Basis von Pflanzenöl, beispielsweise Rizinusöl, Rapsöl, Sojaöl, Sonnenblumenöl und/oder Lingin.In a preferred embodiment, the permanently adhering adhesive comprises a polyurethane, preferably an elastomeric polyurethane. Further preferably, the adhesive comprises polyurethane based on a biogenic polyol, preferably based on vegetable oil, for example castor oil, rapeseed oil, soybean oil, sunflower oil and / or lingin.
In einer weiteren Ausgestaltung enthält das Trägerelement ein Polyurethan bzw. besteht hieraus, vorzugsweise ein elastomeres Polyurethan. Weiterhin bevorzugt umfasst das Klebemittel Polyurethan auf Basis eines biogenen Polyol, bevorzugt auf der Basis von Pflanzenöl, beispielsweise Rizinusöl, Rapsöl, Sojaöl, Sonnenblumenöl und/oder Lingin.In a further embodiment, the carrier element contains a polyurethane or consists thereof, preferably an elastomeric polyurethane. Further preferably, the adhesive comprises polyurethane based on a biogenic polyol, preferably based on vegetable oil, for example castor oil, rapeseed oil, soybean oil, sunflower oil and / or lingin.
Das Trägerelement kann rechteckig, rund oder oval ausgestaltet sein. In einer weiteren Ausgestaltung weist das Trägerelement den oben genannten Klebstoff beidseitig auf. Vorzugsweise weist weiterhin die Haarverlängerung beidseitig Haare auf.The support element may be rectangular, round or oval. In a further embodiment, the carrier element has the above-mentioned adhesive on both sides. Preferably, the Hair extension on both sides hair on.
In einer weiteren Ausgestaltung ist vorgesehen, dass das Trägerelement dünner ist als die Klebstoffschicht, die einseitig oder beidseitig auf das Trägerelement aufgetragen ist. In einer weiteren Ausgestaltung ist das Material des Trägerelements gleich dem Material des Klebers, so dass vorzugsweise nach dem Befestigen der Haare am Trägerelement das Trägerelement und der Kleber nicht mehr unterscheidbar sind, besonders bevorzugt materialverbunden sind. Weiterhin ist bevorzugt, dass das Trägerelement aus dem Material des Klebstoffs besteht und sich insbesondere mit diesem dauerhaft verbindet oder vermischt.In a further embodiment, it is provided that the carrier element is thinner than the adhesive layer which is applied to the carrier element on one side or on both sides. In a further embodiment, the material of the carrier element is equal to the material of the adhesive, so that preferably after fixing the hair on the carrier element, the carrier element and the adhesive are no longer distinguishable, particularly preferably are material-bonded. Furthermore, it is preferred that the carrier element consists of the material of the adhesive and in particular permanently bonds or mixes with it.
In einer weiteren Ausführungsform ist vorgesehen, dass die Haarverlängerung ausschließlich aus den Haaren, dem Trägerelement und dem Kleber besteht.In a further embodiment it is provided that the hair extension consists exclusively of the hair, the carrier element and the adhesive.
Im Gegensatz zu den oben genannten Haarverlängerungsmethoden ist es bei dem vorgeschlagenen Verfahren nicht notwendig, an die Stelle, wo die einzelnen Fremdhaare miteinander verbunden sind, ein weiteres klebendes, durch Hitzeeinwirkung klebendes oder mechanisches Element anzubringen, an dem die Strähne dann an das Echthaar angebracht wird und dessen Vorhandensein später, nach Entfernen der Haarverlängerungssträhne, ihre Wiederverwendung verhindert.In contrast to the hair extension methods mentioned above, in the proposed method it is not necessary to apply to the site where the individual foreign hairs are joined another adhesive, heat-adhesive or mechanical element to which the strand is then applied to the human hair and whose presence later, after removal of the hair extension strand, prevents their reuse.
Wie bereits ausgeführt, stellt das einzige Halteelement der erfindungsgegenständlichen Haarverlängerungssträhne das flexible Trägerelement dar, auf dessen Oberfläche die Fremdhaare haften.As already stated, the only holding element of the inventive Haarverlängerungssträhne represents the flexible support member, on the surface of the foreign hair adhere.
Dieses flexible Trägerelement, das die einzelnen Fremdhaare zu einer Strähne bündelt und gleichzeitig das Element darstellt, an welchem die Haarverlängerung schließlich an das Echthaar befestigt wird, kann in seiner Länge variiert werden beziehungsweise mehr oder weniger gekürzt werden und zwar je nachdem, wie dick beziehungsweise breit die Fremdhaarsträhne ausfallen soll. Ebenso können die Längsseiten des Rechtecks der Trägerelementform an die individuellen Bedürfnisse angepasst werden, indem die Längsseiten verlängert werden, um auf der Innenseite des Trägerelements mehr Haare nebeneinander aufkleben zu können.This flexible support element, which bundles the individual foreign hair into a strand and at the same time represents the element to which the hair extension is finally attached to the human hair, can be varied in length or more or less shortened, depending on how thick or wide the strand of foreign hair should fail. Likewise, the longitudinal sides of the rectangle of the carrier element shape can be adapted to the individual needs by the longitudinal sides are extended in order to glue more hair side by side on the inside of the support member can.
Eine der Ausführungsformen der vorgeschlagenen Erfindung besteht darin, dass an das biegsame Trägerelement in Form von verlängerten Breitseiten bandförmig verstärkte Fäden angebracht werden, die dazu dienen, das Trägerelement vorzugsweise in Längsrichtung weiter auszudehnen.One of the embodiments of the proposed invention is that attached to the flexible support member in the form of extended broad sides strip-shaped reinforced threads, which serve to extend the support member preferably further in the longitudinal direction.
Die Fäden wirken insbesondere als Armierung, so dass das langgestreckte Trägerelement, auf dem die Haare befestigt sind, nicht reißt. Weiterhin ist in einer Ausgestaltung vorgesehen, dass die Fäden sich über das Trägerelement hinaus erstrecken und beispielsweise mit einer weiteren Haarverlängerung kombinierbar beziehungsweise verbindbar ist.The threads act in particular as a reinforcement, so that the elongate support member on which the hair is fixed, does not tear. Furthermore, it is provided in one embodiment that the threads extend beyond the carrier element and, for example, can be combined or connected with a further hair extension.
Wie erwähnt, ist auch das Verfahren zur Befestigung der Haarverlängerung an das Eigenhaar Gegenstand dieser Erfindung. Die Befestigung wird folgendermaßen durchgeführt:As mentioned, the method for attaching the hair extension to the own hair is the subject of this invention. The attachment is carried out as follows:
Ein Teil der Haare oder eine Strähne des Haarverlängerungsträgers wird ausgesondert und zwar derart, dass die ausgewählte Innenseite des Kopfhaares offengelegt wird. Auf die Stelle des Trägerelements an der die Fremdhaare angebracht sind - dem Halteelement - wird ein Klebstoff auf Grundlage von Cyanoacrylat (Alkylcyanacrylat) aufgetragen. Sodann wird die mit Kleber bedeckte Fläche gegen die Innenseite der ausgewählten Haarpartie oder Haarsträhne des Kopfhaares gedrückt, um die Haarverlängerungen mittels der Wirkung des Klebstoffes an das Eigenhaar zu befestigen. Der Klebstoff hat aufgrund seiner Fähigkeit zur anionischen Polymerisation die Eigenschaft, schon bei geringer Konzentration von Hydroxid-lonen zu polymerisieren, die in der Regel schon in der Luftfeuchte gegeben ist. Daher ist er leicht verarbeitbar, solange er vor dem Auftrag von Luftfeuchtigkeit ferngehalten wird.A portion of the hair or a strand of the hair extension carrier is discarded such that the selected inner side of the hair is exposed. In place of the support element to which the foreign hairs are attached - the holding element - an adhesive based on cyanoacrylate (alkyl cyanoacrylate) is applied. Then, the surface covered with adhesive is pressed against the inside of the selected hair part or hair strand of the head hair to attach the hair extensions to the own hair by the action of the adhesive. Because of its ability to anionically polymerize, the adhesive has the property of polymerizing even at a low concentration of hydroxide ions, which is usually already present in the air humidity. Therefore, it is easily processable, as long as it is kept away from the order of humidity.
Dieses Befestigungsverfahren weist mehrere bedeutende Vorteile gegenüber der gegenwärtig üblichen Haarverlängerungsmethoden auf.This method of attachment has several significant advantages over current hair extension methods.
Zuerst funktioniert die Befestigung der Fremdhaare an das Eigenhaar ohne die Zuhilfenahme von Werkzeugen. Des Weiteren können die Haarverlängerungen dann abgenommen werden, wenn der Träger dies wünscht. Und zwar mittels eines Lösungsmittels, das dafür geeignet ist, das Klebemittel zu entfernen. Vorzugsweise wird zur Lösung des Klebstoffes auf Grundlage von Cyanoacrylat (Alkylcyanacrylat) ein Lösungsmittel verwendet, dass Aceton und/oder Butanon, vorzugsweise 2-Butanon umfasst. Weiterhin bevorzugt ist das Lösungsmittel derart gewählt, dass dieses den Kleber nicht löst, der das Fremdhaar am Trägerelement befestigt, besonders bevorzugt ist das Lösungsmittel derart gewählt, dass dieses Polyurethan nicht löst. Diese Methode ist sehr schonend und erlaubt darum auch ohne weiteres die Wiederverwendung der Haarverlängerungen, da der Kleber auf Grundlage von Cyanoacrylat vollständig von der Haarverlängerung beziehungsweise von dem Halteelement lösbar ist.First, the attachment of the foreign hair to the own hair works without the aid of tools. Furthermore, the hair extensions can then be removed if the wearer so desires. By means of a solvent suitable for to remove the adhesive. Preferably, to dissolve the cyanoacrylate (alkyl cyanoacrylate) based adhesive, a solvent comprising acetone and / or butanone, preferably 2-butanone, is used. Further preferably, the solvent is chosen such that it does not dissolve the adhesive which secures the foreign hair to the carrier element, more preferably the solvent is chosen such that this polyurethane does not dissolve. This method is very gentle and therefore also allows the reuse of the hair extensions, since the cyanoacrylate-based adhesive is completely detachable from the hair extension or from the holding element.
Ein weiterer Vorteil des erfindungsgegenständlichen Befestigungsverfahrens ist, dass die Befestigung der Fremdhaare an die Eigenhaare keine weiteren Verbindungselemente braucht, sondern die Haarverlängerungen direkt mit dem Eigenhaar verbunden werden und zwar auf der Innenseite der Eigenhaare, das heißt der Seite der Eigenhaare, die der Kopfhaut zugewandt sind, wenn sie schwerkraftbedingt nach unten hängen. Dadurch wird die Stelle der Befestigung der Haarverlängerung durch das Eigenhaar selbst verborgen.Another advantage of the fixing method according to the invention is that the attachment of foreign hair to the own hairs needs no further connection elements, but the hair extensions are directly connected to the own hair and that on the inside of the own hair, that is, the side of the own hairs, which face the scalp when they hang down due to gravity. As a result, the point of attachment of the hair extension is hidden by the own hair itself.
