The present invention relates to a composition for treating keratin fibres, in particular the hair, comprising: a) at least one amino silicone; b) at least one non-amino silicone having a weight-average molecular weight of less than or equal to 1500 g/mol; c) at least one colouring agent chosen from pigments, direct dyes and mixtures thereof.

Composition comprising at least one amino silicone, at least one non-amino silicone and at least one colouring agent

A subject matter of the present invention is a process for the treatment of keratin fibers, such as the hair, comprising the application, to the keratin fibers, of a composition comprising at least one alkoxysilane chosen from the compounds of formula (I), at least one non amino silicone of formula (II), the non amino silicone(s) of formula (II) having a weight-average molecular weight of less than or equal to 1500 g/mol and at least one coloring agent chosen from pigments, direct dyes and their mixtures, followed by a stage of application of heat to the keratin fibers covered with the composition, using a heating tool, at a temperature of greater than or equal to 45° C. for a period of time of greater than or equal to 15 minutes.

Process for the treatment of keratin fibers employing a composition comprising at least one alkoxysilane of formula (I), at least one non amino silicone of formula (II) having a weight-average molecular weight of less than or equal to 1500 g/mol and at least one coloring agent

The present invention relates to a dye composition for the oxidation dyeing of human keratin fibers, at a pH greater than or equal to 8, comprising at least one oxidation dye precursor, at least one fatty alcohol, at least one fatty ester and at least one cationic surfactant, where the weight ratio of the at least one fatty alcohol and the at least one fatty acid ester being greater than 2 and less than 10. In addition, the present invention relates to a ready-to-use composition obtained by extemporaneously mixing the dye composition with an oxidizing composition, before use, and a method for dyeing keratin fibers in which the ready-to-use composition is applied to hair fibers.
