摘要：
A process for dyeing keratinous fibers comprises a two-step operation in which in the first step the fibers are contacted with an indole dye in a medium suitable for dyeing the fibers, the medium being free from any oxidation catalyst and oxidation catalyst. Thereafter, in the second step the fibers are contacted with a para type oxidation dye precursor in a medium which is also suitable for dyeing the fibers and is free from any oxidation catalyst and oxidation agent. A multi-compartment kit housing the indole dye and para type oxidation dye precursor is also provided.
