Abstract: Disclosed herein are a method of dyeing or coloring, with a lightening effect, a human keratin material comprising applying a composition comprising, in a cosmetically acceptable medium, at least one fluorescent compound and at least one optical brightener; a composition comprising, in a cosmetically acceptable medium, at least one fluorescent compound and at least one optical brightener which are both soluble in the medium; and a device using such a composition comprising at least two compartments, wherein at least one comprises, in a cosmetically acceptable medium, a composition comprising at least one fluorescent compound and at least one optical brightener and optionally at least one additional ingredient chosen from direct dyes, oxidation bases and couplers, and at least one other compartment comprises a composition comprising at least one oxidizing agent.

Abstract: The invention relates to a cosmetic dyeing composition that is used to lighten human keratinous matter and, more specifically, artificially colored or pigmented hair and dark skin. The inventive composition comprises at least one flourescent dye. The invention also relates to the methods using said composition.

Abstract: Compositions for oxidation dyeing of keratin fibers, and in particular of human keratin fibers such as the hair, comprising, in a medium which is suitable for dyeing, at least one heterocyclic oxidation base chosen from pyrazoles, certain pyrimidines, pyrazolopyrimidines and the acid addition salts thereof, and at least one coupler chosen from 2-substituted 5-aminoalkylphenol derivatives and the acid addition salts thereof, as well as dyeing processes using these compositions.

Abstract: Compositions for oxidation dyeing of keratin fibers, and in particular of human keratin fibers such as the hair, comprising, in a medium which is suitable for dyeing, (i) at least one oxidation base, (ii) at least one coupler chosen from 2-substituted 5-aminoalkylphenol derivatives and the acid addition salts thereof, and (iii) at least one additional coupler chosen from meta-phenylenediamines, meta-aminophenols, meta-diphenols, heterocyclic couplers and the acid addition salts thereof, as well as dyeing processes using these compositions.

Abstract: The subject of the invention is a composition for the oxidation dyeing of keratinous fibers, and in particular human keratinous fibers such as hair, comprising at least one oxidation base, chosen from the pyrazolopyrimidines, and, as coupler, at least one N-(2-hydroxybenzene)carbamate or one N-(2-hydroxy-benzene)urea of formula (I), their use as coupler for the oxidation dyeing of keratinous fibers, and the oxidation dyeing methods using them.
