Method for colouring hair comprising pretreating the hair with at least one primer composition before treating the hair with a polymeric hair colouring system.

Method for colouring hair including pretreatment

Method for treating hair comprising the successive application onto hair of polymeric layers which can be removed to a large extent or even totally in an easy manner upon request of the user by using a cationic surfactant.

Hair treatment method and kit thereof

A method for treating hair comprising applying primer(s) and cationic polymer(s) onto a user's hair for improving the styling of the hair in a more manageable and reliable manner and for enhancing the stability of the final style obtained.

Hair styling method and kit thereof

Method for treating hair comprising the application onto hair of polymeric layer(s) which can removed to a large extent or even totally in an easy manner upon request of the user by using oxidizing composition.

Method for treating hair comprising the successive application onto hair of polymeric layers which can be removed to a large extent or even totally in an easy manner upon request of the user by using a composition having a pH of at least 8.5.

The instant disclosure generally relates to a dual component hair coloring composition for coloring mammalian or synthetic keratin fibers, the composition comprising composition A comprising a cationic polymer, pigment microparticles and an aqueous medium, and comprising composition B comprising an anionic polymer, aqueous medium and optional cross linking agent. Optionally or alternatively composition B may contain pigment particles. The cationic and anionic polymers are at least partially soluble in the medium and the pigment microparticles are dispersed therein. The hair coloring composition forms a dual layer coating upon application to keratin fibers such as hair and has a substantially permanent pigment lastingness following development (setting); minimally alters the keratin fibers, upon application; and substantially eliminates development time. Methods of using such compositions are also described herein.

Dual polymer component hair coloring composition

A method for treating hair comprising applying at least one pigment onto hair for providing the basis for colouring hair in a more reproducible and reliable manner independently from a user's initial hair colour.

A process for the production of CS particles () and microcapsules () is described, in which at least one active compound () is adsorbed in porous templates () (A), as a result of which templates () filled with active compounds are present. Subsequently, the templates () are provided (B) with a primer layer () which is intended to facilitate the subsequent construction of the capsule shell (). The capsule shell is formed (C) by applying alternately charged polyelectrolyte layers (). Filled CS particles () are obtained. By subsequent dissolution of the templates () the active compounds () are released (D) from the template into the interior of the microcapsules. The active compounds () remain enclosed there or are slowly released (E) from the capsule.
