Abstract
A kit-of-parts and a process for dyeing keratinous material, such as human hair, are provided. The method includes applying a coloring agent (a) to the keratinous material, wherein the agent (a) includes (a1) at least one amino-functionalized silicone polymer, and (a2) at least one color-imparting compound, and (a3) optionally, a film-forming polymer different from (a1). The method further includes applying a post-treatment agent (b) to the keratinous material, wherein the agent (b) includes (b1) at least one acid, and (b2) optionally, a film-forming polymer. In the method, at least one of the agents (a) and/or (b) comprises at least one film-forming polymer.
