    Abstract: Process for dyeing keratinous fibres, comprising the step of applying to these fibres at least one composition A containing, in a medium appropriate for dyeing, at least one mono- or di-hydroxyindole the application of the composition A being preceded or followed by the application of a composition B containing, in a medium appropriate for dyeing, at least one quinone derivative chosen from ortho- or para-benzoquinones, monoimines or diimines of ortho- or para-benzoquinones, 1,2- or 1,4-naphthoquinones, sulphonimides of ortho- or para-benzoquinones, alpha , omega -alkylene-bis-1,4-benzoquinones, or 1,2- or 1,4-naphthoquinone-monoimines or -diimines; the mono- or di-hydroxyindoles and the quinone derivatives being chosen such that the oxidation-reduction potential difference DELTA E between the oxidation-reduction potential Ei of the mono- or di-hydroxyindoles, determined at pH 7 in a phosphate medium on a vitreous carbon electrode by voltametry, and the oxidation-reduction potential Eq of the quinone derivative determined at pH 7 in a phosphate medium by polarography on a mercury electrode and relative to a saturated calomel electrode is such that DELTA E=Ei-Eq

    Abstract: The present invention relates, firstly, to a cosmetic and/or dermatological composition intended for treating keratin fibres, in particular human keratin fibres and more particularly human hair, comprising, in a support which is suitable for keratin fibres: (a) at least one enzyme of 2-electron oxidoreductase type in the presence of at least one donor for the said enzyme; (b) at least one substantive polymer chosen from the group consisting of: (i) cationic cellulose derivatives; (ii) dimethyidiallylammonium halide homopolymers and copolymers of dimethyidiallylammonium halide and of (meth)acrylic acid; (iii) methacryloyloxyethyltrimethylammonium halide homopolymers and copolymers; (iv) polyquaternary ammonium polymers; (v) vinylpyrrolidone polymers containing cationic units; (vi) mixtures thereof. The present invention also relates to processes for treating keratin fibres, in particular processes for dyeing, permanently reshaping or bleaching the hair using this composition.
