An agent for dyeing keratinous material, in particular human hair, is disclosed. The agent is a colorant composition comprising at least one amino-functionalized silicone polymer, at least one color-imparting compound, and at least one organic carbonic acid ester. A process (method) for dyeing keratinous material with the agent is also disclosed. The process includes applying a colorant comprising the agent to the keratinous material, exposing the keratinous material to the agent for an exposure time sufficient for the color-imparting compound to act on the keratinous material, and rinsing out the keratinous material with water.

The present invention relates to a process for treating keratin fibers, comprising the application to the keratin fibers of a composition (C) comprising at least one (poly)carbodiimide compound, at least one aqueous dispersion of particles of polymer(s) chosen from polyurethanes, acrylic polymers, and mixtures thereof, optionally at least one silicone, and at least one coloring agent chosen from pigments, direct dyes, and mixtures thereof.

Provided is a semi-permanent hair dye composition, and particularly, a foam-type semi-permanent hair dye composition which is easily applied onto the inner part of the hair due to having high foam forming ability and high foam retention and exhibits less color fading after dyeing and excellent colorability. The semi-permanent hair dye composition includes a pigment penetration agent, a cationic surfactant, and a non-ionic surfactant as well as a basic pigment.

The subject of the present disclosure is a method for dyeing keratinous material, in particular human hair. The method includes applying an agent (a) to the keratinous material. The agent (a) includes one or more organic silicon compound selected from the group of silanes having one, two or three silicon atoms, (a2) a first colorant compound including one or more lenticular substrate platelet-based pigment, and (a3) a second coloring compound. The method further includes applying an agent (b) to the keratinous material. The agent (b) includes at least one sealing reagent. Also disclosed are multi-component packaging unit (kit-of-parts) for dyeing keratinous material.
