Agents for the oxidative dyeing of hair, containing as coloring component 6-amino-3-methylphenol, also in the form of its salts or phenolates. The coloring component is contained in these agents in a quantity of about 0.01 to 2.0 percent by weight, alone or in a mixture with the customary developing and coupling substances. In the case of a mixture, the 6-amino-3-methylphenol is preferably used at a molar ratio below normal relative to these developing and coupling substances. The oxidative reaction of the 6-amino-3-methylphenol proceeding with an intensive yellow coloring is generally not influenced by the customary developing and coupling substances that may be present.
A method for dyeing human hair with oxidative dyes which comprises applying to said hair, at temperature of from 15.degree. to 50.degree. C. an effective amount for dyeing, of a mixture of a suitable oxidizing agent and an aqueous composition containing from 0.01 to 2.0% by weight of 6-amino-3-methyl-phenol, allowing said mixture to remain in contact with said hair for a period of time to effectively dye said hair, and thereafter rinsing said hair.
