The present invention relates to a process for treating keratin fibres, especially the hair, comprising the following steps: —application to the keratin fibres of a composition comprising one or more cationic acrylic copolymers comprising at least the units obtained from the following monomers: a) monomer derived from acrylic or methacrylic esters or amides and comprising at least one cationic group, and b) alkyl acrylate or methacrylate monomer, and—application of heat to the keratin fibres using a heating tool, the application of heat possibly taking place before, during or after the application of the composition, preferably during or after.

Removable hair coloring compositions are described herein that include: at least one hair color composition or compound; and at least one sealing component or compound, wherein at least one of the at least one hair color composition or compound, or the at least one sealing component or compound can be physically dissolved, physically removed, or a combination thereof when mixed with at least one natural oil. In some embodiments, removable hair coloring compositions further include at least one preparation stage component or compound.

It is an object of the present disclosure to provide an agent for coloring keratinous material, in particular human hair, comprising (a1) at least one amino-functionalized silicone polymer, and (a2) at least pigment,
the weight ratio of all the pigments (a2) contained in the composition to all the amino-functionalized silicone polymers (a1) contained in the composition, i.e., the weight ratio (a2)/(a1), being not more than 0.95.

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

A method to produce an effective cool tone with blonde hair color, while performing the hair dyeing process. To that end, the desired blonde hair color may be achieved by incorporating pigmented capsules and/or any pigmentation agent into the hair bleach mixture and/or the hair peroxide mixture. The pigmentation agent provides a cool tone effect while simultaneously removing unwanted yellow and orange undertones from hair during the hair bleaching process. Accordingly, the method includes producing pigmented hair bleach mixture and pigmented hair peroxide mixtures for performing the hair lightening process. However, it is important to note the scope of the method includes incorporation of pigmented capsules and/or any pigmentation agent into any and all related hair dyeing or hair coloring and hair care products to achieve toning of hair.

A multi-chrome cosmetic hair composition is disclosed. The composition includes a base formula suitable for hair and an interference pigment providing a colored background exhibiting interference colors that are observable at different angles of observation. The formula is sufficient to enable a homogenous suspension of the interference pigment. The formula includes a propellant, denatured alcohol, neutralized octylacrylamide/acrylates/butylaminoethyl methacrylate copolymer 4, a neutralizing agent sufficient to neutralize the octylacrylamide/acrylates/butylaminoethyl methacrylate copolymer 4 to a range of 80% to 100%, and a plasticizer. The interference pigment includes an opaque-type interference pigment consisting of particles ranging from 5 microns to 60 microns in size to fill in gaps on hair shaft surfaces and create a smooth, chrome-like effect on the hair. The interference pigment includes an inorganic layer that specularly reflects incident light and semi-transparent inorganic layers that refract the reflected light such that the interference colors are observable.

The subject of the present invention is an aerosol device comprising a composition for dyeing keratin fibers, comprising at least one copolymer resulting from the polymerization of at least one crotonic acid monomer or crotonic acid derivative and of at least one vinyl ester monomer, at least one fatty amine and at least one pigment. The invention also relates to a dyeing process wherein said composition is applied to keratin fibers, the operation optionally being followed by drying.

The present invention relates to an aqueous composition comprising at least one dispersion of polymer particles in a non-aqueous medium, at least one cationic polymer and at least one anionic polymer.
