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.

Dyeing process employing indole dyes and oxidation dye precursors and

An anti-solar cosmetic composition contains as the anti-solar agent a compound of the formula ##STR1## wherein R represents a member selected from the group consisting of hydrogen, a halogen selected from the group consisting of chlorine and fluorine and alkyl containing 1-4 carbon atoms; R' and R' each independently represent a member selected from the group consisting of hydrogen and SO.sub.3 M wherein M represents a member selected from the group consisting of hydrogen, organic ammonium group and a metal, wherein at least one of R' and R' is other than hydrogen, and R' is a substituent at the para or meta position relative to the bornylidene ring. The anti-solar agent is present in amounts of 0.5-10 percent by weight of said composition.
