The invention relates to a process for treating keratin fibres, in particular human keratin fibres such as the hair, comprising the application to the keratin fibres of a cosmetic composition comprising a pyridinedicarboxylic acid compound. The process makes it possible to obtain good cosmetic properties in terms of manageability of the hair and sheen, with a long-lasting effect.

Process for treating keratin fibres with a pyridinedicarboxylic acid compound

The invention relates to i) a process for treating keratin fibres, in particular human keratin fibres such as the hair, employing a) at least one oxidized polysaccharide, in particular oxidized inulin, and b) at least one (poly)saccharide with amine group(s); ii) a composition comprising the ingredients a) and b); iii) the use of a) and b) to treat keratin fibres, in particular human keratin fibres such as the hair, and iv) a multi-compartment kit or device comprising a) and b). The invention makes it possible to obtain good hair-conditioning cosmetic properties, with a long-lasting effect.

Process for protecting and repairing keratin fibres, based on oxidized polysaccharide and on (poly)saccharide with amine group

The invention relates to a process for treating keratin fibres, in particular human keratin fibres such as the hair, comprising: (i) a step of applying an oxidized polysaccharide, (ii) a step of heating to a temperature of at least 100&#xb0; C., (iii) a step of applying a pyridinedicarboxylic acid compound. The process makes it possible to obtain good hair-conditioning cosmetic properties, with a long-lasting effect. The invention also relates to a cosmetic composition and a kit used for performing the treatment process.

Process for treating keratin fibres with a polysaccharide and a pyridinedi-carboxylic acid compound

The invention relates to a process for treating keratin fibres, in particular human keratin fibres such as the hair, comprising: &#x2022;(i) a step of applying an oxidized polysaccharide, &#x2022;(ii) a step of heating to a temperature of at least 100&#xb0; C., &#x2022;(iii) a step of applying a compound (I) &#x2022;R&#x2014;CHOH&#x2014;CH(NH&#x2014;COY)(CHOH) (I). The invention also relates to a cosmetic composition comprising an oxidized polysaccharide and a compound (I) for which Y&#x2550;H and to kits. The process makes it possible to obtain good hair-conditioning cosmetic properties, with a long-lasting effect.

Process for treating keratin fibres with an oxidised polysaccharide and a sphingosine compound

The present invention relates to a cosmetic treatment process for keratin fibers which have not been artificially colored, in particular human keratin fibers such as the hair, which consists in using one or more anionic oxidized polysaccharides and in raising the temperature of the keratin fibers.

Process for protecting and repairing keratin fibres using anionic oxidized polysaccharides

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&#x2014;C(O)OAin which R denotes a C-Calkyl group, and Adenotes 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.
