ABSTRACT:
A composition and process are disclosed for oxidative coloring of hair on the basis of at least one substituted phenol of the general formula ##STR1## whereby R.sub.1 represents a hydroxy alkyl group with 1 to 4 carbon atoms and R.sub.2 a hydrogen atom or alkyl group with 1 to 4 carbon atoms, or the phenolate thereof, as a coupler substance. The inventive coupler substance, of which 2-hydroxy-methyl-5-methyl-phenol and 3-(.beta.-hydroxy ethyl)-6-methyl-phenol are preferred, should be present in a concentration of about 0.01 to 3.0% by weight, in particular 0.1 to 2.0% by weight. The described coupler substances are active as blue couplers. The obtained color shades are stable, resistant to wear and very well reproducible. They have very favorable characteristics with respect to toxicology and dermatology and do not give the colored hair an unpleasant, penetrating cresolic aroma. The process involves forming an oxidizable developer-coupler combination of a developer substance with the substituted phenol as coupler substance, and an oxidation agent, applying a coloring-effective amount of the combination onto human hair, rinsing the hair after about 10-45 minutes at a temperature between 15.degree. and 50.degree. C., and drying the hair.
