摘要:
The present invention relates to a process for dyeing dark keratin fibres, which comprises the application to the fibres of a composition containing at least one anionic chromophore-containing coloured polyelectrolyte, wherein the application is not followed by a rinsing step. Such a process makes it possible to obtain a coloration which is easy to carry out and which preserves the cosmetic appearance of the keratin fibres.
摘要:
The invention relates to a leave-in hair dyeing process using a composition comprising a coloured polymer and an oil. Such a process makes it possible to obtain a coloration which is easy to carry out and which preserves the cosmetic appearance of the keratin fibres.
摘要:
The present invention relates to a process for dyeing keratin fibres, which comprises the application to the fibres of a composition containing at least one cationic polymer, rinsing of the keratin fibres, the application of a composition containing at least one anionic colored polymer, and rinsing of the keratin fibres.Such a process makes it possible to obtain an improvement in the coloration of the keratin fibres.

摘要:
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.

摘要:
Provided is a dyeing composition for coloring human keratin fibers, comprising, at a pH less than 8, in a cosmetically acceptable medium, at least one oxidative dye precursor; at least one cationic surfactant; at least one fatty acid ester; and at least one fatty alcohol, wherein the at least one fatty alcohol is chosen from non-(poly)oxyalkylenated and non-(poly)glycerolated, saturated and unsaturated fatty alcohols, and wherein the weight ratio of the at least one fatty alcohol to the at least one fatty acid ester is greater than 2:1 and less than 10:1. Also provided are methods and devices for coloring the keratin fibers.
摘要:
The present invention relates to a dyeing composition for the oxidative dyeing of human keratin fibres, at a pH less than 8, comprising one or more oxidative dye precursors, one or more fatty alcohols and fatty esters as well as one or more cationic surfactants, the weight ratio of fatty alcohol(s) to fatty acid ester(s) being greater than 2 and less than 10.It also relates to a ready-to-use composition obtained by extemporaneous mixing with an oxidizing composition prior to using the aforementioned dyeing composition.It also relates to a method of colouring keratin fibres in which the ready-to-use composition is applied on said fibres.According to another variant of the method of colouring, the aforementioned dyeing composition and the oxidizing composition are applied successively and without intermediate rinsing.The invention also relates to a device with several compartments that are suitable for its application.
