    Abstract: The subject of the present invention is a process for the oxidation dyeing of keratin fibers, in particular human keratin fibers such as the hair, implementing: a) a step of treating said fibers by application to said fibers of a cosmetic composition (A) comprising: i) at least one fatty substance in an amount of greater than 10% by weight relative to the total weight of the composition (A), at least one metal catalyst; ii) at least one coupler; iii) optionally at least one oxidation base, preferably chosen from para-phenylenediamines, bis(phenyl)alkylenediamines, para-aminophenols, ortho-aminophenols, heterocyclic bases, addition salts thereof and solvates thereof; b) optionally a washing, rinsing, drying and/or rubbing-dry step; c) a step of treatment by application to said fibers of an oxidizing cosmetic composition (B) comprising at least one chemical oxidizing agent; and it being understood that steps a), b) and c) can be carried out successively a), then b), then c), or else a) then c), followed by b). The dyeing process makes it possible to significantly improve the dyeing properties of the coloration, in particular in terms of selectivity, of chromaticity, and of color intensity and uptake. The use of a composition which is rich in fatty substances, i.e. greater than 10%, and contains at least one catalyst, as a pretreatment, before oxidation dyeing, allows a clear improvement in the dyeing properties, in particular in terms of dye uptake onto keratin fibers, of strength and of chromaticity and of selectivity of the color.

    Abstract: The present invention relates to a process for the oxidation dyeing of keratin fibers implementing: a) a step of pretreating said fibers by application to said fibers of a cosmetic composition (B) comprising: i) at least one fatty substance in an amount of greater than or equal to 10% by weight relative to the total weight of the composition (B); and ii) at least one metal catalyst; b) optionally a washing, rinsing, drying and/or rubbing-dry step; c) followed by a step of dyeing by application to said fibers of a cosmetic composition (A) comprising: i) at least one oxidation base, preferably chosen from para-phenylenediamines, bis(phenyl)alkylenediamines, para-aminophenols, ortho-aminophenols, heterocyclic bases preferably comprising at least two nitrogen atoms, and addition salts thereof; ii) optionally at least one coupler; and iii) at least one chemical oxidizing agent. The dyeing process makes it possible to significantly improve the dyeing properties of the coloration, in particular in terms of selectivity, of chromaticity, and of color intensity and uptake. The use of a composition which is rich in fatty substances, i.e. greater than 10%, and contains at least one catalyst pretreatment, before oxidation dyeing, allows a clear improvement in the dyeing properties, in particular in terms of dye uptake onto keratin fibers, of strength and of chromaticity and of selectivity of the color.

    Abstract: The present invention therefore relates in particular to an aqueous cosmetic composition comprising one or more fatty substances in a content ranging from 40% to 80% by weight, relative to the total weight of the cosmetic composition, one or more oxyethylenated fatty alcohols having a number of oxyethylenes less than or equal to 10, one or more alkylpolyglucoside-type surfactants; the present invention also relates to using the cosmetic composition in an oxidative colouring or bleaching method for keratin fibres, particularly human keratin fibres such as hair.
