[0460] i. First Example of Combination Administration

[0461] a) Preparation of the composition

[0462] Compositions (A1) comprising triarylmethane dyes of formula (I) according to the invention were prepared from the ingredients whose contents are mentioned in the table below.

[0463]

[0464] Fluorescent dye-containing compositions (B1) and (B2) were prepared from the ingredients whose contents are mentioned in the table below.

[0465]

[0466] b) program

[0467] The compositions (A1), (B1) and (B2) obtained above were mixed to obtain the following mixture:

[0468] - A1+B1 in a 1 / 1 ratio, and

[0469] - A1+B2 in a 1 / 1 ratio.

[0470] 10 ml of compositions (A1), (B1), (B2), (A1+B1) and (A1+B2) were applied to 1 g of hair tresses.

Abstract

Process for dyeing keratin fibres using at least one particular triarylmethane dye and at least one fluorescent dye The present invention relates to a process for dyeing keratin fibres, in particularhuman keratin fibres such as the hair, using one or more particular triarylmethane dyes and one or more fluorescent dyes. The present invention also relates to a cosmetic composition comprising the dyes defined above, and also to a multi-compartment device containing said dyes. The present invention also relates to the use of said dyes for dyeing light keratin fibres, especially human keratin fibres such as the hair, in chestnut-brown, dark chestnut-brown, brown, brown with a glint, or even black, without using an additional dye other than those defined above.

Description

technical field [0001] The present invention relates to a method for dyeing keratin fibers, in particular human keratin fibers such as hair, using one or more specific triarylmethane dyes and one or more fluorescent dyes. [0002] The present invention also relates to a cosmetic composition comprising a dye as defined above, and also to a multi-compartment device comprising said dye. [0003] The present invention also relates to said dyes for dyeing light-colored keratin fibers in chestnut brown, dark chestnut brown, brown, brown with shimmer, or even black, without the use of additional dyes other than the dyes defined above, Especially the use of human keratin fibers such as hair. Background technique [0004] Many people have long sought to change the color of their hair, and especially to cover up their gray hair. [0005] A particularly known practice is to dye keratin fibers, especially human keratin fibers, with dye compositions containing oxidation dye precursors,...
