ABSTRACT:
The subject invention concerns novel dye compositions and a process for dyeing keratinous fibers, for example, hair, to give a pleasing and stable colored product. The dye composition is a novel combination of three elements to give a dye that, unexpectedly, has highly desirable dyeing properties. This unique combination comprises (1) a suitable organic compound to assist dye dispersion, (2) dye precursors including dopamine, D-dopa, L-dopa, D,L-dopa, or analogs thereof, and (3) iodate or periodate. Desired color variations can be obtained by the use of appropriate color modifiers.
