Oxidizable developer-coupler combinations wherein the coupler is a water-soluble polyhalogen 3-aminophenol are stable in the absence of free oxygen and chemical oxidizing agents. They provide hair dyeings of specially desirable shades. The dyeings are color fast, wash-fast, thermostable, and non-toxic. The combinations can be applied in customary vehicles. Their dyeing properties are developed by air oxidation, by peroxides, or by both at an acid, neutral or alkaline pH.
