The present invention relates to a process for dyeing keratin fibers, in particular human keratin fibers such as the hair, using a) one or more blue, violet or green dyes and b) one or more disulfide, thiol or protected-thiol 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 fibers, notably human keratin fibers such as the hair, in chestnut-brown, dark chestnut-brown, brown, brown with a tint, or even black, without using an additional dye other than those defined above.

Process for dyeing keratin materials using at least one blue, purple or green dye and at least one disulfide, thiol or protected thiol fluorescent dye

The instant disclosure relates hair care compositions comprising ionic liquids or ionic mixtures. Ionic liquids or ionic mixtures are combined with a cosmetically acceptable carrier to form ready-to-use hair care compositions. The ionic liquids and the ionic mixtures are formed from; (1) thiolactic acid and/or one or more alkali metal or alkaline earth metal salts thereof; and (2) one or more amine compounds, and/or one or more ammonium cationic compounds, and/or one or more salts thereof. The ionic liquids, the ionic mixtures, and the hair care compositions comprising the ionic liquids or the ionic mixtures, are useful in methods for preventing hair damage, shaping hair, caring for hair, etc.

Hair care compositions comprising thiolactic acid-based ionic liquids or thiolactic acid-based ionic mixtures

The invention relates to a cosmetic composition, especially a hair composition, and to a method for the cosmetic treatment of keratin materials, especially of the hair, employing compounds of formula: in which Z represents (i) a hydrogen atom, (ii) a linear or branched C1 to C32 (saturated) alkyl radical; (iii) a linear or branched C2 to C32 (unsaturated) alkene radical, comprising one or two C&#x2550;C double bonds; (iv) an aryl-substituted alkyl radical; said radicals being optionally substituted and/or interrupted.

Cosmetic composition, cosmetic treatment method, kit, and compound

The invention relates to a process for dyeing and/or lightening keratin fibres using direct dyes of styryl or naphthyl-amide type bearing a (C-C)aminoalkyl group. The dyeing process and the composition according to the invention make it possible in particular to obtain long-lasting, intense, chromatic and/or homogeneous colouring on the keratin fibres.

Composition for dyeing keratin fibres, comprising a styryl or naphthylamide direct dye bearing an aminoalkyl function, dyeing process and dye

The present invention relates to a process for dyeing keratin fibres, in particular human keratin fibres such as the hair, using one or more particular azinium 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.

Process for dyeing keratin fibres using at least one particular azinium dye and at least one fluorescent dye

The present invention relates to a process for dyeing keratin fibres, in particular human 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.

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 particular human keratin fibres such as the hair, using one or more particular 2- or 4-azopyridinium 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.

Process for dyeing keratin fibres using at least one particular 2- or 4-azopyridinium dye and at least one fluorescent dye

The present invention relates to a cosmetic process for treating keratin materials, which can give them, especially in a long-lasting and reversible manner, interesting cosmetic properties; this process comprising the application to said materials:  The invention also relates to a kit comprising said compositions.

Cosmetic treatment processes and kit

The invention relates to a composition for dyeing keratin materials, and in particular human keratin fibres such as the hair, comprising at least one 2-pyrrolidone functionalized in the 4 position with an ester or amide radical, and at least one hydrophobic direct dye or a pigment; a dyeing process using this composition. Similarly, the invention relates to the use of the said pyrrolidone combined with a direct dye or a pigment for dyeing keratin materials, and especially to the use of the said pyrrolidone for improving the colour uptake onto the fibres of direct dyes that are sparingly soluble or insoluble in aqueous-alcoholic supports. The invention also relates to novel pyrrolidone derivatives. The present invention makes it possible in particular to obtain direct dyeing on keratin materials that is fast, resistant to washing, chromatic and powerful.
