DESCRIPTION:
BRIEF SUMMARY
The invention relates to an apparatus for lengthening a person's own hair using artificial and/or genuine hair and for permanently fastening artificial and/or genuine hair; the invention also relates to the method applied in this regard when using the above apparatus.
BACKGROUND OF THE INVENTION
Biosynthetic achievements including the extension of and permanent attachment to tufts of a person's own hair, i.e. hair that is growing naturally out of the scalp, using genuine and/or artificial hair. Such techniques are used on the one hand for medical applications, though primarily for cosmetic applications. A person's own hair can be lengthened, not to mention thickened, in that a person's own hair and the genuine and/or artificial hair fastened thereto is cut to the same length. In technical fields, a great many systems are known for lengthening and thickening a person's own hair; such systems are described in the 21/94 edition of the "Top Hair Special" magazine. In accordance therewith, a person's own hair can be extended by using artificial or genuine hair by means of special binding and knotting techniques and by various adhesive techniques.
U.S. Pat. No. 5,107,867 describes a hair extension method in which strands of the hair to be extended are joined using a heat-resistant adhesive in order to form a graft on a strand of extension hair, whereupon a coating consisting of a plastic material that is fusible when heat is introduced is applied to this graft. Strands of the person's own natural hair are then threaded through a shrinkable tube portion, the graft of extension hair pretreated in the above-described manner is also inserted into the shrinkable tube and this shrinkable tube treated by application of heat. Either a heating iron, which is described in further detail, or another suitable device can be used. On the one hand, the application of heat causes the tube to shrink, on the other hand the fusible adhesive melts and produces a permanent connection between the natural genuine hair and the strand of extension hair. The tube is intended to protect the connection from environmental influences, but it is also intended to act as a hair care product. If heat is re-applied to the shrinkable tube, the hair extension can be removed once again.
This and other techniques in which adhesives are used make it necessary for a person to after-treat his/her own hair once the hair extension has been removed. Residual adhesive sticking in a person's own hair has to be removed by using a suitable solvent, usually acetone. This results in damage to a person's own hair, particularly as the hair extension methods need to be repeated at regular intervals, approximately every 6 weeks. When solvents are used for such a frequent treatment of the natural hair of the head, a person's own hair may be destroyed at the connecting points.
SUMMARY OF THE INVENTION
The present invention aims to develop an apparatus of the aforementioned type for lengthening a person's own hair and for permanently fastening artificial and/or genuine hair; such an apparatus allows a person's own hair to be lengthened or an extension strand or a hair-piece to be permanently fastened in a simple and inexpensive manner without damaging a person's own hair in the process.
The invention's object is solved in that in the aforementioned type of apparatus, a tube which can be shrunk when energy is applied is disposed around a positionally secured, thickened portion, particularly a knot in a strand of a person's own hair, and around a strand of artificial or genuine hair; and energy means transfers energy, particularly heat, to the shrinkable tube.
The advantage of this invention lies in the fact that without applying adhesive, the mechanical connection between a person's own hair and an extension strand of artificial or genuine hair occurs by means of shrinking the tube on an area where there is a positionally secured, thickened portion, such as a knot in a person's own hair.
This knot makes an important contribution toward the connection's stability b
