Abstract
A method for dyeing keratinous material, such as human hair, is described. Initially, a first agent is applied to the keratinous material. The first agent includes less than 10 wt % water, at least one organic silicon compound selected from the group comprising silanes having one, two, or three silicon atoms, and at least one chromophoric compound. A second agent is applied to the keratinous material which is still impinged with first agent. The second agent includes water. The first and second agents are allowed to act upon the keratinous material. The first and second agents are then rinsed.
