Abstract

Official abstract text for this publication.

An agent for dyeing keratin material, such as human hair, may include at least two organosilicon compounds different from each other. Each organosilicon compound may be independently selected from silanes with one, two, or three silicon atoms, and the organosilicon compound may include one or more hydroxyl groups and/or hydrolyzable groups per molecule. The agent may include at least one pigment, and at least one fatty component that is liquid at 20° C. and/or an organic solvent. The agent may be used for dyeing keratin material.
