Abstract
The invention relates to a method for forming a catalyzed dye system. The method includes the successive steps of (1) forming a mixture comprising at least one dye precursor and a catalyst and (2) adding an alkalizer to the mixture, which forms a catalyzed dye system. The dye system may be exposed to hair for less time than standard oxidative dye systems, which is believed to result in reduced damage to hair.
