摘要：
The invention relates to a composition for dyeing keratinous fibres, in particular human keratinous fibres such as hair, comprising, in an appropriate dyeing medium, at least one cationic direct dye of a given formula, and which is characterized in that it contains, in addition, at least one anionic surfactant chosen from the group consisting of acyl isethionates, acyl taurates, sulphosuccinates, acyl sarcosinates, acyl glutamates, polyoxyalkylenated ether carboxylic acids and their salts, fatty glucamide sulphates, alkyl galactoside uronates, anionic derivatives of alkyl polyglucosides and mixtures thereof. The invention also relates to the dyeing methods and devices using it.
