Abstract

The subject of the present disclosure is a method for dyeing keratinous material, in particular human hair. The method includes applying an agent (a) to the keratinous material. The agent (a) includes one or more organic silicon compound selected from the group of silanes having one, two or three silicon atoms, (a2) a first colorant compound including one or more lenticular substrate platelet-based pigment, and (a3) a second coloring compound. The method further includes applying an agent (b) to the keratinous material. The agent (b) includes at least one sealing reagent. Also disclosed are multi-component packaging unit (kit-of-parts) for dyeing keratinous material.
