Abstract
Provided is a ready-to-use composition for the oxidation dyeing of keratin fibers, and for example of human keratin fibers such as the hair, comprising: A) at least one fatty substance present in an amount of greater than or equal to 25% by weight relative to the total weight of the ready-to-use composition, at least one of the at least one fatty substance being chosen from fatty amides and fatty acid esters, B) at least one dye precursor, C) at least one oxidizing agent and optionally D) at least one alkaline agent. Also provided is a method of dyeing of keratin fibres, comprising applying a ready-to-use composition to the keratin fibres for a sufficient time to develop the desired coloration.
