Definitions

  • Hair weaving systems and techniques are commonly used to lengthen or increase the fullness of human or animal hair, such as show horses.
  • Hair weaving consists of gluing, heat- bonding, or crocheting synthetic or natural human or animal hair ("weave hair") onto layers of a subject's existing hair.
  • weave hair synthetic or natural human or animal hair
  • the existing hair is divided into sections, and the weave hair is then either glued or fused with wax onto the existing hair sections.
  • the existing hair is braided along the scalp and the weave hair is then stitched with a strong weaving thread onto the braids.
  • the weave hair may be stitched onto a skull cap that is fixed to the subject.
  • weave hair particularly when it consists of natural human hair, can be very expensive, so it is frequently used repeatedly before it is discarded. Although some weave hair may be used for up to one year before it should be discarded, it must be frequently removed from the existing hair to allow for tightening and cleaning.
  • Glued or heat-bonded weave hair may be removed through application of hair oils that loosen the chemical bonds between the weave hair and the existing hair. This technique can be messy, however, and is not effective on more attractive, crocheted weaves.
  • a hair stylist or groomer When removing crocheted weave hair, a hair stylist or groomer will typically cut each stitch of the hair weave with clippers or scissors.
  • the hair stylist or groomer typically must tug on the weave hair and attempt to insert a blade of the clippers or scissors between the weave hair and the tight stitches. This process of tugging, inserting, and cutting can be time consuming, painful, unsanitary, and damaging to the expensive weave hair and the subject's body and existing hair. Points of the blades frequently also slip and nick the stylist's, groomer's, or subject's skin, resulting in pain, infections, and even transfer of disease. Even without cutting of the subject's skin, use of the same scissors or clippers on multiple subjects can transfer lice or other contaminants. Because the clippers or scissors are typically reused without being sterilized, techniques such as these can pose a dire risk to all involved.
  • a hair weave removal apparatus for removing hair weave stitches has a handle and a tip extending from and retractable within the handle.
  • the tip has a first extending portion, a second extending portion, a linking portion between the. first extending portion and the second extending portion, and a sharp edge.
  • the sharp edge is on the linking portion, the first extending portion, or both.
  • the first extending portion also includes a blunt surface on an opposite side of the first extending portion than the linking portion.
  • the first extending portion also includes a distal end with a width smaller than a width of the hair weave stitches.
