Abstract
An oxidation dye composition for keratin fibers, in particular for human keratin fibers such as the hair, comprising, in a medium which is suitable for dyeing, at least one oxidation dye precursor and optionally one or more couplers, and also an anionic amphiphilic polymer containing at least one hydrophilic unit, and at least one allyl ether unit containing a fatty chain. The oxidation dye compositions are used in dyeing processes and dyeing kits.
