Definitions

  • the present invention relates to the sector of lengthening and thickening of hair and, more precisely, regards a product and method for application of locks of hair on a person's head.
  • a thick, abundant, rich head of hair that is luminous and soft is always deemed an index of beauty, youth, and well-being.
  • long and well-groomed hair has always represented in western culture the quintessence of female beauty. The loss of hair has undoubtedly a significant impact on the perception that others have of a person.
  • Thin and brittle hair may consequently be viewed as a sign of premature ageing and may be such as to generate insecurity in a person as regards his or her social and relational capacities. Generally, for the person concerned, this represents a serious problem at a psychological level. Above all, women who suffer from loss of hair may feel particularly fragile, unattractive, and weak. Numerous studies indicate that loss of hair causes anxiety, depression, and reduced sel f-assurance .
  • the extensions can be applied in a number of small locks, which are to be applied individually, seeking to distribute them evenly over the head, or in a single large lock that extends over the entire head of hair, or in portions of variable length according to the thickening requirements.
  • Hair extensions of an adhesive type present the disadvantage of rendering the portion of hair heavy and of creating at times an unnatural appearance at the roots of the hair, creating a far from attractive final aesthetic effect.
  • a horizontal parting is formed to separate the hair on one side and the other of the parting.
  • the hair above the parting is lifted up and fixed with a clip, and the extension is positioned and fixed along the parting.
  • the clips are closed, blocking in between a lock of hair.
  • the hair extensions fixed with the clips must rest firmly and smoothly on the head and moreover must be kept at a distance of 2-3 mm from the hair line to prevent any unpleasant sensations.
  • the method also requires quite a large amount of covering hair to be left free to render the clips invisible and to get them to blend as much as possible into the hair.
  • Clip extensions in general present the disadvantage of being less secure than adhesive ones.
  • the method for fixing hair extensions that uses keratin represents the technique that is least aggressive and most secure for the hair and is also able to guarantee a longer-last ng result, which obviously depends also upon the rate of re-growth of the hair.
  • the system envisages that the mini locks that are to be applied at the base of the hair should be coated with a layer of keratin-based glue.
  • a lock of original hair of the subject is selected below a parting formed in the hair. The portion of hair below the parting is the one that is used for application of the hair extensions.
  • the lock of hair extensions with the portion coated with keratin-based glue is set attached to the scalp, and with one's fingers the glue is made to adhere properly to the hair in such a way as to glue the locks of hair extensions and the original locks of hair together. Then, with a hot plate or iron the glue is heated so that, by melting, it fixes properly and definitively glues together the hair of the two types of locks, the original ones of the subject and those of hair extensions. After cooling, the keratin-based permanent hair extension is properly fixed.
  • the method most widely adopted does not use glue or synthetic materials for application of hair extensions; instead, a small transverse braid obtained using the original hair is simply made on the head adherent to the skin, and the weave of hair extensions is sewn on the braid with a thread.
  • the latter is formed with small locks of hair of the extension that are mixed at the base with the real hair, and then a braid is formed with the real hair together with the hair of the extension.
  • the braid itself that functions as perfect natural bond for the hair extension applied, and in practice it is not necessary to use any other system for fixing the hair that is applied.
  • the braid has to be small, made up of locks of just a few hairs each, in so far as an excessively large braid would be visible underneath the hair extensions that are applied. Furthermore, if the braid is too thick, the hair could be somewhat difficult to dry completely after it has been washed.
  • Okyo Sthair in the U.S. patent application No. US2009/0071490, entitled “Self-applicable Integrated Self Addition”, describes an integrated hair addition having a central elliptical opening, suited for being blended into the natural hair of the subject.
  • Keratin-type hair extensions which on the other hand represent the solution of choice to obtain a stable, long-lasting, and aesthetically professional result present the disadvantage of not being reusable, because during removal the bonding point breaks, and the lock of original hair itself breaks up. Instead, hair extensions applied with adhesive can be reused after the adhesive has been replaced, as likewise hair extensions of a weave type or ones applied with clips, provided that they are kept in good conditions.
  • the main purpose of the invention is to overcome the problems of known systems by providing a new system for lengthening and thickening hair that envisages a weave, fixed in a non- removable way to which are the ends of a plurality of locks of real or synthetic hair, provided with respective means for gluing to the locks of hair of the subject to whom the hair extensions are to be applied.
  • Figure 1 is a front view of the weave, or weft, of a lock of hair extensions according to the i nventi on .
  • the subject of the present invention is an innovative hair extension constituted by a weave, or weft, (1) of natural or synthetic human hair.
  • the weave consists of a single piece of variable length, which may preferably reach even one metre in length, from which the operator that carries out application of hair extensions cuts portions of different length according to the needs or wishes of the user in order to integrate and thicken the person's head of hair.
  • connection weave (12) which gathers and fixes said ends of natural or synthetic human hair adjacent to one another so as to form small locks of hair (13) set in orderly fashion in succession in a horizontal direction to develop the length of the weave.
  • a thread of silk, or of some other functionally and structurally equivalent material, is incorporated in the connection weave (12) in order to provide a unitary support for the weave or for the portion of weave that is used.
  • the amount of hair to be applied by means of hair extensions depends obviously upon the thickness, length, and/or volume of hair of the subject to whom they are to be applied, in order to guarantee an even, harmonious, and aesthetically pleasing effect. This effect is obtained by evaluating carefully and choosing adequately the thickness of the weave to be applied.
  • the thickness of the weave varies according to the specific weight of the locks of hair, which is in turn determined by the thickness of the locks, by the thickness of the hair, and by the length of the hair.
  • the length of the locks of hair (13) that constitutes the weave initially ranges from 30 to 55 cm, and when the application is completed this length can be reduced according to the final desired hai rstyl e .
  • the locks (13) of hair may be made up of hair (11) of the same colour or of different colours according to the final chromatic effect that it is desi red to create .
  • Another peculiar characteristic of the weave of hair extensions according to the present invention consists in envisaging, on the locks of hair of the weave, deposition of a preferably (but not exclusively) keratin-based adhesive composition.
  • the subject of the invention is the particular arrangement of this adhesive composition in the proximity of the weave (12), and not its compos t on, since, according to the invention, any type of keratin-based adhesive composition commonly employed and known to operators of the sector may be used.
  • the keratin-based adhesive composition is deposited on the locks in a discontinuous way at a distance of approximately 1-2 cm, preferably 1 cm, from the connection weave, to form paral 1 el epi pedal accumulations or blocks (14) having a width ranging from 4 to 10 mm, preferably 6 mm, and a height ranging from 1 and 5 mm, preferably 3 mm.
  • the thickness of each block (14) of adhesive composition is slightly greater than that of the lock of hair, generally 3-5 mm.
  • the lock of hair of the weave at the corresponding block (14) of adhesive composition is completely englobed in the adhesive composition.
  • the blocks (14) of adhesive composition set at a distance of approximately 1 cm from the connection weave are evenly distributed at a distance of 0.5-1 cm from one another throughout the length of the weave (12) itself.
  • the method of application of the weave (12) of hair extensions, or of a portion thereof of a length selected on the basis of the final effect that it is desired to obtain consists in heat fixing in a classic way the locks of hair of the weave provided with the keratin-based adhesive to the original hair of the subject by means of a heating clamp that melts the adhesive that constitutes the block (14).
  • the weave (12) of ha r extensions consists in heat fixing in a classic way the locks of hair of the weave provided with the keratin-based adhesive to the original hair of the subject by means of a heating clamp that melts the adhesive that constitutes the block (14).
  • (I) - or a portion thereof - is momentarily fixed using classic alligator hair clips, or similar implements designed for temporary and reversible fixing, to the skin at the point of application of the extension where a horizontal parting of the locks of natural hair has been purposely created to make room for the weave.
  • the natural lock and the lock of the extension are set up against one another and pressed for a few seconds with the heating clamp at a temperature adequate for melting the keratin-based adhesive (14) or the adhesive of some other suitable type.
  • the point of bonding of the two locks is then squeezed between the thumb and the forefinger so as to ensure good adhesion.
  • the hair extensions according to the invention may last from 2 to 4 months, obviously according to the care and attention with which the hair is treated.
  • the process of removal of the adhesive bonds is performed according to the standard methods known to operators of the sector using an adequate solvent designed to dissolve the adhesive (14), whether it is keratin-based or of some other type, and a metal cl amp .
  • a first advantage of the invention consists in providing a type of weave (12) of hair extensions that, unlike the keratin-type hair extensions currently known, can be reused after the adhesive has been dissolved and the hair (11) and the weave (12) have been thoroughly cleaned, in so far as the hair
  • connection weave or strip (12) only acts as element for connection of the locks (13), but does not intervene in providing and constituting the fixing of the hair extensions. Consequently, it does not generate any pain, reddening, or irritation of the skin of the subject .
  • the locks (13) are not applied individually but in a multiple way, generally along a horizontal line on the skin of the scalp, through application of a weave (12), or of a portion thereof of variable length according to the thickening needs, application of hair extensions according to the invention guarantees a final effect that is aesthetically more homogeneous and harmonious in a given area or sector of the head, with the result that the hair falls naturally and smoothly and without any alteration of the thickness and weight of the locks so that the natural hair is not tugged and the person that is to wear the hair extension does not experience any hurt or discomfort.
  • the weave (12) has a thickness that is substantially the same as that of the locks of hair of the extensions.
  • an additional thread of natural or synthetic material (not shown) to pass in the weave (12), for example using a needle for wool, so as to be able to fasten the weave with the locks (13) of hair (11) temporarily at the desired height on the head of the subject, so that the locks (13) of extensions are firmly held in position, without any clips, during their application/fixing to the hair of the subject.
  • This additional thread is then slid out of the weave (12) at the end of fixing of the locks (13) .
