A cosmetic composition for improved dyeing of keratin fibers is described. The composition comprises alkoxylated organopolysiloxanes and alkoxylated glyceryl esters and/or optionally alkoxylated alkyl glyceryl ethers. The composition may comprise less than 40 wt % water, or may be anhydrous. The composition may further comprise a direct dye, and may be used for bleaching, lightening, or dyeing of keratin fibers.

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.
