Compositions and processes for dyeing keratin fibers with an oxidation base, a coupler, a cationic direct dye, and an oxidizing agent

摘要

A ready-to-use composition for the oxidation dyeing of keratin fibers, in particular human keratin fibers such as hair, this composition comprising at least one oxidation base selected from para-phenylenediamines and bis(phenyl)-alkylenediamines, in combination with at least one coupler selected from meta-phenylenediamines, at least one selected cationic direct dye and at least one oxidizing agent, as well as to the dyeing process using this composition.
