Embodiment

[0058] The composition is applied to natural chestnut brown hair:

[0059] -1 / using platifiz from the company L'Oréal  As a pretreatment agent for oxidative bleaching;

[0060] -2 / Using platifiz, a product of the company L'Oréal  As a post-treatment agent for oxidative bleaching.

[0061] In the pretreatment, the hair is treated with the composition for 30 minutes at a temperature of 37 ° C and rinsed with water with Platifiz  Bleach, rinse thoroughly again before drying.

[0062] As an after-treatment, condition the hair with Platifiz before treating it with the composition  Bleach, rinse with water, then rinse thoroughly again before drying.

[0063] After these treatments, the hair was smoother, softer and more manageable than without pre- or post-treatment.

[0064] Additionally, the treatments of the present invention did not alter the level of bleaching.

Abstract

The present invention relates to the use of compositions containing at least one specific aminosilicone as a pre- or post-treatment agent for the bleaching of human keratin fibers, more particularly hair. The present invention also relates to a method of bleaching human keratin fibers, more particularly hair, comprising pre- or post-treatment with a composition comprising at least one specific aminosilicone.

Description

technical field [0001] The present invention relates to the use of a composition comprising at least one specific aminosilicone as a pre- or post-treatment agent for the bleaching of human keratin fibers, more particularly hair. [0002] The invention also relates to a method of bleaching human keratin fibers, more particularly hair, comprising pre- or post-treatment thereof with a composition comprising at least one specific aminosilicone. Background technique [0003] The natural color of dark hair can be lightened in a permanent manner by bleaching, and the same applies when the hair has been artificially colored with direct or oxidative dyes and wishes to remove it. [0004] Bleaching compositions for these treatments consist of ready-to-use thickened aqueous hydrogen peroxide compositions. However, they are mainly in the form of anhydrous products (powders or creams) containing basic compounds (amines and alkali silicates) and oxidizing agents capable of generating per...
