Abstract

Methods and compounds are provided for oxidative coloring of keratinic fibers, in particular hair. The method includes applying a pretreatment agent onto the hair, where the pretreatment agent includes at least one 4-morpholinomethyl-substituted silicone. A hair coloring agent is applied to the hair subsequent to the pretreatment agent within a time span from about 1 second to about 24 hours. The hair coloring agent is obtained by mixing a composition (A), which contains at least one oxidation dye precursor of the developer type and at least one oxidation dye precursor of the coupler type, with a composition (B) that contains at least one oxidizing agent. Composition (B) contains at least one cosmetic oil in a total quantity from 10 to 80 wt %, based on the weight of composition (B).
