Description

The present invention relates to a method for dyeing hair from a composition comprising a dye precursor, an agent and a method for dyeing hair from a composition comprising a dye precursor, an oxidizing agent and an organic silicon compound. oxidant and an organic silicon compound. The hair is generally damaged and weakened by the action of external atmospheric agents such as light and weather, and by mechanical or chemical treatments such as brushing, combing, discoloration, perms and / or dyes. As a result, the hair is often difficult to discipline, in particular they are difficult to disentangle and comb, and the hair, even abundant, particularly difficult to maintain a good looking hairstyle due to the fact that the hair lack of vigor, of volume and nervousness. This degradation of the properties of the hair is also increased by permanent hair coloring treatments, which consist in applying to the hair one or more dye precursors such as oxidation bases and couplers and an oxidizing agent. These precursors under the action of the oxidizing agent will form in the hair one or more colored species. At the same time, it has been found that consumers are increasingly in search of compositions which make it possible not only to color the hair satisfactorily but also to provide satisfactory styling effects. In particular, people with fine or curly hair are generally looking for a styling effect bringing mass, body and volume to fine hair and drawing curly hair curls. It is usual to apply after coloring hair conditioning products that provide disentangling and improve the touch, but these products do not provide enough styling effects including body, mass or volume. There is therefore a real need to implement a permanent hair dyeing process with dye precursors such as oxidation bases and couplers, which does not have the drawbacks described above, that is to say say that can lead to sufficient styling effects including body, mass or volume and more, these effects should preferably be persistent to shampoos and external aggressions with good cosmetic properties, and all this regardless the sensitization of treated hair.

The object of the present invention is therefore to provide a hair dyeing method which allows the hair to be dyed satisfactorily with a sufficient and lasting styling effect.
