Abstract

The present invention is directed to embodiments of a method for coloring hair using an oxidative hair coloring composition based upon the primary dye compounds MBB, Aminol and optional secondary precursor and coupler compounds PAP, DPE, MAP, AHT and EOAP, a carbonate and/or bicarbonate source, an alkalizer and one or more amino acids. Additional subsidiary precursors and couplers may be included to broaden the color space delivered by the primary dye compounds. The oxidative hair coloring composition is free of resorcinol and C1-C10 alkyl resorcinol. The L*a*b* color space of embodiments of the oxidative hair coloring composition as measured by L*a*b* techniques is about the same as that delivered by the resorcinol based composition.
