Abstract

A process for dyeing keratinous material is disclosed. The process includes applying an agent (a) and an agent (b) to the keratinous material. The agent (a) comprises (a1) at least one organic silicon compound, and (a2) at least one sulfated and/or sulfonated fatty acid ester. The agent (b) comprises (b1) at least one sealing reagent, and (b2) at least one first colorant compound. A multi-component packaging unit is also disclosed, and comprises, separately packaged, a first container comprising an agent (a′), a second container comprising an agent (a″), and a third container comprising an agent (b). The agent (a′) comprises (a1) at least one organic silicon compound. The agent (a″) comprises (a2) at least one sulfated and/or sulfonated fatty acid ester. The agent (b) comprises (b1) at least one sealing reagent, and (b2) at least one first colorant compound.
