Zusammenfassung: | Compositions for the treatment of keratin fibres, especially human hair, which comprise in a cosmetic carrier (A) at least one biotin compound of the formula (I) in which M' is a hydrogen atom, a (C1 to C6)-alkyl group, a (C2 to C6)-hydroxyalkyl group, a (C2 to C6)-alkenyl group, an equivalent of a singly or multiply charged cation and (B) at least one optionally hydrated SiO2 compound, are suitable for hair care and for reducing the ageing of hair. In addition, the active ingredient combination as part of a combination product for care and simultaneous colour changing has the effect of an intense and colourfast colouring of the substrate. |
