Abstract: The present invention relates to a process for treating keratin fibres, comprising the application to the fibres i) of at least one nucleophilic alkoxysilane polymer, in particular at least one aminoalkoxysilane polymer, and ii) at least one aliphatic-chain activated (thio)ester. The invention also relates to a cosmetic composition comprising ingredients i) and ii) and to a kit comprising ingredients i) and ii) for performing such a process. The process gives the treated damaged fibre a long-lasting hydrophobic surface state, the hydrophobicity effect being persistent after one or more shampoo washes, while at the same time affording a good cosmetic feel.

Abstract: The invention relates to a cosmetic process for treating keratin fibers, comprising a step of applying, to the keratin fibers, a first cosmetic composition comprising an amino polymer comprising a primary amine group, followed by a step of applying a second cosmetic composition comprising an activated ester of formula R—C(O)OA1 in which R denotes a C5-C21 alkyl group, and A1 denotes a particular reactive group and in particular a succinimide group. The invention also relates to a kit comprising a first cosmetic composition comprising said amino polymer and a second cosmetic composition comprising said activated ester, the first and second compositions each been packaged in a separate packaging assembly. The process gives the treated damaged fiber a long-lasting hydrophobic surface state, the hydrophobicity effect being persistent after one or more shampoo washes, while at the same time affording a good cosmetic feel.
