Embodiment Construction

[0235] The hair fiber treatment method according to the invention is carried out by using a reducing composition and a care composition.

[0236] Reducing Composition B

[0237] Cysteine ​​4g

[0238] Hydroxypropyl Guar Gum 0.5g

[0239] Mexomere PO 2.5g

[0240] Monoethanolamine Appropriate to pH 9.2

[0241] Appropriate amount of water to 100g

[0242] Care composition D

[0243] Cetearyl Alcohol 1.5g

[0244] Steareth-20 0.5

[0245] WACKER-BELSIL ADM LOG 11 3.5

[0246] Appropriate amount of water to 100g

[0247] The hair fiber treatment method according to the present invention is carried out by using a hair dryer or a flat iron as means for raising the temperature.

[0248] 1) Embodiment of the method using a hair dryer

[0249] The advantage of this method is that it is quick and less technical, allowing the model to apply it on its own.

[0250] Hair (natural, medium curly) was washed with a standard shampoo followed by dehydration.

Abstract

Shaping hair fibers, comprises: (i) applying on the hair fibers a reducing composition comprising one or more cationic polymer, where the weight ratio of reducing composition on the concentration of cationic polymer is 0.1-10 wt.%, and the application is followed by a rinsing; (ii) application of a care composition (II), preferably not rinsed, comprising one or more aminated silicone; and (iii) raising the temperature of the hair fibers using heating means at a temperature of 50-280[deg] C, before or after the optional rinsing of hair fibers.

Description

technical field [0001] The present invention relates to a method for the treatment of hair fibers and the use of said method. Background technique [0002] In order to obtain a permanent deformation of the hair, the disulfide bonds in keratin (cystine) are usually first opened by means of a composition containing a reducing agent, followed by a second step, preferably after rinsing the hair, by means of a smooth or pre- An oxidative composition (also known as a fixative) is applied to the hair, which has been tightened by suitable means (such as curlers), to restructure the disulfide bonds in order to give the hair the desired style. This technique allows to achieve curling of the hair, or straightening of curls, or their curling, or their smoothing, without distinction. [0003] The reducing compositions useful in carrying out the first step of these methods typically contain thiol-containing compounds such as thioglycolic acid, cysteine, cysteamine, thiollactic acid, thio...
