The invention provides compositions and methods for the oxidative coloring of human hair. The compositions of the invention contain as a primary dye intermediate a 1-(4-aminophenyl) pyrrolidine, or a cosmetically acceptable salt thereof. The compositions may also contain at least one other primary intermediate and conventional coupling compounds, in addition to an oxidizing agent and other components typically used in oxidative hair dye preparations. Preferred dye intermediates in the compositions of the invention include 1-(4-aminophenyl) pyrrolidine and 1-(4-amino-3-methylphenyl) pyrrolidine, or cosmetically acceptable salts thereof, which produce intense neutral colors when used in admixture with a suitable coupling agents, such as 3-aminophenol, in conventional hair dye base formulations.
