Abstract
A composition and method for the oxidative dyeing of hair based on a combination of coupler substance and developer substance, wherein they contain (A) 5-amino-2-methylphenol as coupler substance and (B) 4-amino-3-methylphenol and (C) 1,4-diaminobenzene and/or 2,5-diaminotoluene as developer substances, also in the form of the physiologically compatible salts. The new composition enables the production of neutral red color shades which are free from yellow and virtually free of blue portions and, in addition to the high dye intensity and brilliance, have an outstanding dye equality with very good absorptive power.
