Definitions

  • the present invention relates to a method for hair extension and / or hair thickening.
  • the change of shape or color of the head hair to change the appearance is well known and widely used. Short-term styling through hair gels or hair sprays and longer-lasting styling such as perms as well as the coloring or bleaching are secured state of technical knowledge and can be carried out to a large extent in home use.
  • the foreign hair is thereby strands firmly connected with the own hair. This can be done by heat, ultrasound or mechanically. Another possibility is the incorporation of tresses, is worked in rows. The attachment takes place especially at the back of the head, so that sufficient own hair falls from the top of the head over the joints.
  • thermoadhesive, wax, keratin or a silicone base When modulating with heat, thermoadhesive, wax, keratin or a silicone base is used at approx. 90 - 130 ° C.
  • the keratin platelets On ultrasound, the keratin platelets (so-called bonding) are briefly heated at the molecular level; mechanical methods using plastic or metal sleeves work without heat.
  • a hair extension lasts up to 6 months, the costs vary greatly depending on the quality of the hair used and the method of incorporation used.
  • hair extension methods are from the documents JP 03152205 (Aderans Co. Ltd.) and in the ZA 93/5214 A or in the DE 196 26 107 C1 described. Methods in which an adhesive is applied to the resulting compound, for example, in US 4,934,387 (Megna). A method of attaching a self-adhesive strand of hair is in the US-A-6,135,122 disclosed.
  • the DE 202 03 301 U1 finally discloses a device and a method in which several strands of hair are present with splices on a common carrier film and can be applied simultaneously.
  • the US 6,446,636 discloses hair extension methods in which at least one strand of hair provided with a fastener is used. Hair extensions are also in the US2006 / 196296 A1 (Gill ) disclosed.
  • the US 6,446,636 B1 discloses a method of attaching additional strands of hair to natural hair wherein an adhesive composition of non-thermoplastic resin (eg polyvinyl alcohol), dye and perfume is placed in the hair to adhere a strand of hair.
  • non-thermoplastic resin eg polyvinyl alcohol
  • the US2006 / 169296 A1 describes a hair extension procedure using double-sided adhesive tape.
  • an at least hair strand is provided, which is provided with a fastening element.
  • a strand of hair consists of a hairpiece to which a fastener is attached.
  • the hairpiece consists of a plurality of natural and / or artificial fibers ("strand of hair").
  • Natural (“real") hair often comes from India or China, as hairstyles are often traditionally long. In India, the braids are partially cut off for religious reasons. Today, most human hair comes from India. Animal hairs can also be used according to the invention; buffalo belly hair, for example, has proved to be useful in this case.
  • the hair is washed, sorted by length, curled and dyed. Partially, the outer cuticle layer is removed to prevent felts.
  • Hair strands which can be used according to the invention can also be produced from synthetic hair.
  • a widely used material is synthetic fibers of poly (acrylonitrile-co-vinyl chloride) from Kanekalon. Strands in which both natural hair and synthetic fibers are present next to each other, are suitable according to the invention.
  • a fastener On the hairpiece is a fastener, which is preferably attached to one end of the hair strand. An attachment of the fastener in other places, for example in the middle of a strand of hair is also possible - but this is indeed produced by the length of the strand of hair an unnatural strands course.
  • the fastener is therefore at one end (hereinafter referred to as "upper end") of the Haarstsrähne before.
  • the fastener is preferably small and thin dimensioned so that the subsequent attachment point on the head is not noticeable.
  • Preferred fasteners have spatial dimensions in the millimeter range, for example, heights of 1 to 4 mm and lengths or widths of 5 to 80 mm, preferably from 10 to 70 mm, more preferably from 20 to 60 mm and in particular 30 to 50 mm.
  • the fastener In order to be usable in the method according to the invention, the fastener must be able to be swollen by solvents. This is ensured by the fact that the fastener - based on the weight of the fastener - contains at least 10 wt .-% synthetic (s) polymers (e).
  • the fastener - based on the weight of the fastener - at least 25 wt .-%, more preferably at least 50 wt .-%, still more preferably at least 75% by weight and in particular at least 90% by weight of synthetic polymer (s).
  • synthetic polymers refers to plastics which can be prepared by all polyreaction polyadditions, polycondensations and polymerizations and polymer-analogous reactions customary for the synthesis of polymers.
  • the fastening element according to the invention comprises at least one polyurehane (PU) polymer.
  • PU polyurehane
  • Polyurethane is the collective name for polymers in whose macromolecules the repeating units are linked by urethane groups -NH-CO-O-. Polyurethanes are generally obtained by polyaddition from dihydric or higher alcohols and isocyanates according to
  • R 1 and R 2 may stand for low molecular weight or even already polymeric aliphatic or aromatic groups.
  • fastener - based on the weight of the fastener - at least 10 wt .-%, preferably at least 25 wt .-%, more preferably at least 50 wt .-%, even more preferably at least 75 wt. -% and in particular at least 90 wt .-% polyurethane polymers).
  • the attachment of the previously provided strand of hair to the own hair is carried out in the process according to the invention by treating the fastener with a solvent.
  • the fastener swells and becomes so adhesive that it can be attached to a strand of hair of the own hair.
  • the solvent then evaporates and the attachment site loses its tackiness.
  • the evaporation of the solvent according to the invention can be assisted by heat (for example by a drying hood or the use of a hot air hair dryer), but this is not necessary according to the invention.
  • solvents which swell the fastening element quickly and reliably and rapidly evaporate after application of the strand.
  • Physiologically largely harmlessness is another criterion in the selection of suitable solvents.
  • Particularly preferred processes according to the invention are characterized in that the solvent is selected from acetone (DMK), isopropanol, hexane, methyl ethyl ketone (MEK) and ethyl acetate.
  • individual strands of hair are each provided with a fastening element and each strand of hair secured to the own hair by swelling the fastener by applying at least one solvent to the fastener and attaching to (each) a strand of hair of the own hair and allowing the solvent to evaporate.
  • the method according to the invention can apply a plurality of strands at the same time. This can be conveniently achieved by applying a plurality of strands with their fasteners to a substrate (e.g., a filmstrip) and then applying solvent to a plurality of fasteners located on the substrate. In this way, hair strands are attached to the own hair at different points in an application step.
  • a substrate e.g., a filmstrip
  • Such a device of hair strands which can be used according to the invention consists of a number of strands of hair, which are preferably arranged in alignment and substantially parallel, and which consist of a number of substantially predetermined hairs, which may be natural or artificial and suitably have selected colors monochrome or with highlights.
  • the strands of hair are preferably arranged at substantially equal intervals. They extend from their respective ends to the fasteners which are adapted to be connected to the hair of the head to their free ends.
  • Such a device also comprises a carrier tape on which the fastening elements are arranged.
  • the material forming the carrier tape is preferably thin and film-like. It can be removed after the evaporation of the solvent from the own hair, which, however, can cause uncomfortable "Ziepen". Preferred are carrier tapes that are so thin and inconspicuous that they can remain in the hair, without disturbing the wearer or attract attention.
  • the carrier tape consists of absorbent material.
  • the application of the solvent is facilitated and promotes the swelling of the fasteners.
  • the hair strand (s) provided with a fastening element additionally comprises / has a carrier band which consists of absorbent material.
  • the carrier tape may in this process variant have a defined length and wear only a single or a predetermined number of strands of hair, or it may have an undefined length, so that the executing person can cut off sections to obtain the desired number of strands of hair.
  • the operator may remove one or more strands of hair that are incompatible with the current application simply by cutting off a portion of the carrier tape.
  • the strands of hair may be the same length, size and color, but it is also possible to provide variations in length to produce stepped extensions, as well as color variations to create complex strands and different sizes.
  • a preferred variant of the method according to the invention is characterized in that a plurality of hair strands are provided, which are mounted in alignment and substantially parallel with their fastening elements on a carrier tape.
  • the carrier tape consists of absorbent material.
  • the carrier tape consists of absorbent paper, preferably of filter paper.
  • the required solvent is already in the fastener, ie the polymer is already in the swollen state and can be applied spontaneously.
  • this embodiment requires a special outer packaging. A blistering which is diffusion-stable with respect to the solvent is preferably used. The application of the hair strands can be made directly after removal from the outer packaging, such as the Blistering.
  • the attachment of the device according to the invention is preferably carried out close to the scalp.
