  公开（公告）日：2002-01-24

  The present invention relates to methods for dyeing keratinous fibers, without significantly damaging the hair. According to the method of the present invention the fibers are treated in a dry state by contacting said fibers with at least one oxidoreductase and at least one dye precursor. In this way it is possible to dye, e.g. human hair, in a simple and efficient manner.
