Hair dye for dyeing keratinic fibres, especially human hair, uses a composition made by mixing together, immediately prior to application to the hair, three separate components (A), (B) and (C) where component (A) comprises at least one precursor of an oxidation dye and optionally at least one coupler in an appropriate medium; component (B) is in powder form and comprises a direct dye optionally dispersed in a pulverulent (in)organic excipient; and component (C) comprises at least an oxidising agent in a suitable medium. |
