Abstract

The subject of the present disclosure is a process for dyeing keratinous material, in particular human hair. In one example, the process includes applying an agent (a) to the keratinous material. The agent (a) contains at least one organic silicon compound from the group of silanes with one, two or three silicon atoms. The agent (a) further contains at least one silicone polymer. An agent (b) is applied to the keratinous material. The agent (b) contains at least one pigment.
