ABSTRACT:
A sequential method for dyeing hair which comprises: contacting the hair with a substantially inactive dye precursor mixture containing at least one primary intermediate and an optional coupler for a period of time, followed by applying a means for aligning the hair and distributing the oxidative dye precursors uniformly, followed by contacting the hair with a developer mixture capable of oxidizing the hair dye precursors to react and form hair color molecules.
