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.

Compositions and methods for inhibiting and interrupting biofilm formation, and for destabilizing established biofilms are provided, the novel compositions including polymeric resins and monomeric non-polymerizable and polymerizable resins. More particularly, the compositions and methods enable the protection and removal of biofilms from surfaces in the context of medical, consumer, domestic, food service, environmental and industrial applications, where the effects constitute beneficial and desirable biofilm attenuating activity.

A second subject matter is a method for dyeing keratin material, wherein the agent is applied to the keratin material.

A process for decolorizing keratinous material which has been colored by the application of at least one pigment is disclosed. The process comprises applying to a dyed keratin material a decolorizing agent comprising at least one amphoteric and/or zwitterionic surfactant and a pH of from about 1.0 to about 4.3. The process further comprises rinsing the decolorizing agent from the keratin material after a contact time. A method for dyeing and later decolorizing human hair is also disclosed, and comprises applying a colorant to the hair to give a dyed hair, the colorant comprising at least one amino-functionalized silicone polymer and at least one pigment; applying to the dyed hair the decolorizing agent to give a decolorized hair; and rinsing the decolorizing agent from the decolorized hair. A multi-component packaging unit comprising a first container comprising the colorant and a second container comprising the decolorizing agent is also disclosed.
