Definitions

  • the present invention relates to an instrument for selectively de-colorating locks of hair, i.e. for producing streaks or the so-called coups-de-sol eil in the hair.
  • Locks de-coloration is commonly practiced by hairdressers. Basically the hair must be de-colored selectively by locks while leaving unaltered the hair adjacent to the lock being treated.
  • the treatment may consist of a decoloration to remove the natural or pre ⁇ existing color of the hair and/or of a pigmentation of the separated, out lock of hair to give to lock of the hair a desired color, different from the natural or pre- existent color.
  • the process of color alteration of the hair takes place essentially through a decoloration process, i.e.
  • the two steps of the process take place substantially through a single treatment which consists in wetting the hair locks to be treated with a dyeing liquid which is com ⁇ monly a mixture of pigments, stabilizers, carriers thickening agents and the like, as for example a ix- ture containing P-phenylenediamine , aminophenols , resorcine, ⁇ -naphthol , ammonia, isopropyl alcohol, carriers, to which, immediately before proceedinging to the treatment of the hair, a de-colorating or bleaching a- gent is normally added.
  • a dyeing liquid which is com ⁇ monly a mixture of pigments, stabilizers, carriers thickening agents and the like, as for example a ix- ture containing P-phenylenediamine , aminophenols , resorcine, ⁇ -naphthol , ammonia, isopropyl alcohol, carriers, to which, immediately before proceeding to the treatment of the hair, a
  • This de-colorating or bleaching agent is commonly constituted by hydrogen peroxide or by a similar oxidizing compound.
  • the hair must remain in contact with the dyeing mixture for a relatively long time, in the order of 15 to 40 minutes or longer.
  • the de-coloration processes may be accelerated by exposing the -hair wetted with the dyeing mixture to heat, commonly by treating the wetted hair under an hairdressing dryer. At the end of the treatment the hair must be accurately rinsed for removing the dyeing fluid while the treated hair locks have absorbed and fixed the pigment. In view of the treatment conditions, it is evident the difficulty and complexity of the treatment when a selective dyeing of locks must be performed.
  • hairdressers utilize a technique which implies the application over the hair of a plastic cap provided with uniformely distributed small cuts or pin holes through which the hair locks are patiently extracted by means of a hook.
  • This preparatory opera- tion for the dyeing treatment is time consuming and often fastidious to the client because of inevitable accidental pulling of hair while the locks are being pulled out of the cuts of the cap.
  • a fastidiousness which often becomes more pronounced during the subsequent treatment of the pulled out locks because of a growing irritation due to the feeling of constriction that the cap produces.
  • a main objective of the present invention is to provide an instrument which would permit to de- colorate a single lock of hair at the time without the need for setting protective caps and at the same time reduce or maintain within economical limits the time necessary for performing the treatment.
  • the instrument of the present invention is composed of a pair of jaws capable of defining a channel therebetween by closing one on the other througn a pincers movement in order to grip between the two jaws a lock of hair which had previously been laid over one of the two jaws.
  • One of the two jaws may contain a pad which may be wetted with a fluid dyeing mixture for. de-colorating hair, in order that when a lock of hair is gripped between the two jaws is pressed against the surface of the wetted pad and therefore is itself wetted with the dyeing mixture.
  • a lock closed between the two jaws may be wetted with a liquid dyeing mixture which is purposely injected through a injection port under the control of the opera- tor.
  • At least one of the two jaws may be provided with electrical heating elements, which may also be control ⁇ lable by the operator, capable of heating to a preestab- lished temperature an internal surface of the jaws in direct contact with the hair of the lock gripped between the two jaws. It has been found that a lock of hair may be completely and satisfactorily de-colorated in a total time which may vary between 40 seconds and about 3 minutes, i.e. compatible with the requirement of maintaining the total time for treating the whole head, within economical limits of normal pro essional hairdressing.
  • the outstanding shortness of the time necessary for de-colorating each singled-out lock of hair is due to the fact that the heating elements are essentially brought directly in contact with the hair wetted with the dyeing mixture and may reach a peak temperature which may be adjustable between 60°C and 130°C. Upon the attainment of these temperature levels, though for short periods of time, the de-coloration process of hair is extremely enhanced and produces a complete de- coloration very quickly.
  • the pad When one of the two jaws is provided with a pad to be saturated with the dyeing liquid, the pad may consist of a porous, substantially elastic mat of a material which will resist to the maximum temperature reached by the heating elements in contact with the hair.

Abstract

Instrument permettant la décoloration sélective de mèches de cheveux. Il comporte une paire de mâchoires (1, 2) aptes à se refermer l'une sur l'autre à la manière des tenailles, et délimitant entre elles une rainure dans laquelle on peut placer et immobiliser la mèche de cheveux voulue. Un injecteur (13) injecte dans ladite rainure une quantité prédéterminée de colorant afin de mouiller la mèche de cheveux. De préférence, l'une (2) des mâchoires possède une surface intérieure chauffée électriquement (17) et destinée à entrer en contact avec les cheveux afin d'accélérer le processus de teinture de la mèche. Cet instrument permet de réaliser un traitement mèche-par-mèche afin d'obtenir l'effet 'coup de soleil' sans que l'on n'ait à protéger le reste des cheveux à l'aide d'un bonnet de protection.
