Compositions for oxidation dyeing keratinous fibers comprising at least one oxidation precursor, and at least one direct dye, and dyeing methods

摘要

Compositions for oxidation dyeing keratinous fibers, for example, human keratinous fibers such as hair, comprising, in a medium suitable for dyeing, at least one oxidation precursor chosen from 1-(4-aminophenyl)pyrrolidines and acid addition salts of formula (I), and at least one direct dye and processes comprising such compositions.
