The present invention relates to a process for treating keratin fibres, especially the hair, comprising the following steps: &#x2014;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&#x2014;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.

Hair treatment process using a composition comprising at least one cationic acrylic copolymer

The present invention relates to a process for treating keratin fibres, in particular human keratin fibres such as the hair, comprising: 1) a step of applying to the keratin fibres a composition comprising: a) one or more compounds chosen from urea and/or urea derivatives, b) one or more polyols, c) one or more amino silicones, 2) a step of heat treatment of the keratin fibres, the heat treatment step 2) preferably being after step 1). The present invention also relates to a composition that may be used in the process according to the invention.

Process for treating keratin fibres, comprising the application of a composition comprising urea or a derivative thereof, a polyol and an amino silicone

The present invention relates to a non-dyeing composition comprising: (i) 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, the alkyl radical comprising from 1 to 30 carbon atoms, preferably 1 to 22 carbon atoms, better still 1 to 10 carbon atoms and preferentially 2 to 6 carbon atoms. and (ii) one or more conditioning agents chosen from functionalized silicones, cationic polymers and cationic surfactants, and mixtures thereof.
