Abstract
The present disclosure relates to a composition for coloring keratin fibers comprising in a cosmetically acceptable medium, at least one compound X of polyorganosiloxane comprising siloxane units of a formula (I) and compound Y of organosiloxane comprising at least one alkylhydrogensiloxane unit of a formula (III), wherein when compounds X and Y are placed in contact with each other they react together via a hydrosilyation reaction, at least one hydrophobic direct dye having a log P greater than 2, and optionally at least one organic solvent. The composition of the disclosure makes it possible to obtain varied hues and intense colors on the keratin fibers. Moreover, the coloration is very resistant to external agents, for example, to repeated washing.
