Abstract
A hair coloring composition, and a method for using the composition in which a natural plant-derived chemical of the formula ##STR1## is employed as a coupler-modifier in a composition containing a primary intermediate and a customary coupler. The novel coupler-modifiers produce a composition which is more physiologically suitable for use in hair colorings than the prior art compositions and allows for the preparation of compositions which produce highly stable colorings over a broad range shades and tones.
