Abstract: The invention relates to a process for dyeing and/or lightening keratin materials, in particular keratin fibres, preferably human keratin fibres such as the hair, using at least one fluorescent direct dye bearing a disulfide, thiol or protected-thiol function and comprising at least one aliphatic chain of formula (I). The invention also relates to the use i) of at least one fluorescent direct dye bearing a disulfide, thiol or protected-thiol function (I) combined with ii) steam and/or a heating iron for straightening keratin fibres, for dyeing and lightening keratin materials, and to novel fluorescent direct dyes bearing a disulfide, thiol or protected-thiol function of formula (I), and also a cosmetic composition comprising same.The process used and the use of the thiol, protected-thiol or disulfide fluorescent direct dyes of formula (I) combined with steam makes it possible especially to obtain long-lasting colouring with care valency on keratin materials.

Abstract: A subject of the invention is a process for dyeing keratin fibres such as the hair, using at least one cationic direct dye bearing a disulfide, thiol or protected-thiol function and comprising at least one ammonium group bearing an aliphatic chain (I). Another subject of the invention is the use i) of at least one cationic direct dye bearing a disulfide, thiol or protected-thiol function (I) combined with ii) steam and/or a heating iron for straightening keratin fibres, for dyeing keratin fibres, and novel cationic direct dyes bearing a disulfide, thiol or protected-thiol function (I), and also a cosmetic composition comprising same. The process used and the use of the thiol, protected-thiol or disulfide dyes combined with steam makes it possible in particular to obtain a long-lasting colouration with a care valency on the keratin fibres.

Abstract: The invention relates to a process for treating keratin fibres, in particular human keratin fibres such as the hair, comprising: (i) a step of applying a compound (I) and also the acid or base salts thereof, the optical or geometrical isomers thereof, and the solvates thereof such as hydrates, in which compound of formula (I): R1, R2, R3, R4, x, m, n, X−, are as defined in the description; (ii) a step of heating the keratin fibres to a temperature of at least 100° C., preferably ranging from 100 to 250° C.; it is understood that steps (i) and (ii) may be performed at the same time or separately. The process makes it possible to obtain good hair-conditioning cosmetic properties, with a long-lasting effect.The invention also relates to the novel compounds and to a cosmetic composition comprising such a compound.
