A method for strengthening and repairing keratin fibres including providing a first—and a second crosslinking composition, wherein the first—crosslinking composition comprises an at least bi-functional Brønsted-base and the second—crosslinking composition comprises—an at least bi-functional organic acid, and a cosmetically acceptable carrier; applying the first—as well as the second—crosslinking composition to keratin fibres; and optionally mixing the first—crosslinking composition into a commercially available hair coloring or hair bleaching composition.

The present disclosure relates to hair care compositions such as hair treatment compositions and hair lightening compositions, methods for treating hair (e.g., lightening hair), and to kits comprising the compositions. The components of the hair treatment compositions may be included in hair lightening compositions and used to lighten and/or color hair. The hair treatment compositions typically include: (a) one or more polycarboxylic acids, and/or a salt thereof; (b) one or more amino acids, and/or a salt thereof; and optionally (c) one or more cationic conditioning agents. The hair lightening compositions further include (d) one or more bleaching agents.

The invention relates to a non-therapeutic cosmetic use of fructans of Agave tequilana, containing natural inulins for protecting capillary fibre by improving the hydrophobicity of the capillary fibre. The invention also relates to a non-therapeutic cosmetic method comprising the therapeutic application of fructans of Agave tequilana containing inulins having a degree of polymerisation greater than 10, in order to protect the capillary fibre by improving the hydrophobicity of the capillary fibre, said application being optionally followed by rinsing.

The present disclosure relates to a solid hair cosmetic composition comprising—based on the total weight of the cosmetic composition—0.1 to 40.0% by weight of at least one polysaccharide, at least one polysaccharide being starch from corn, rice, potato or tapioca; modified starch; hydroxypropyl starch phosphate or a dextrin, and optionally: 10.0 to 60.0% by weight of at least one polyhydric alcohol, 0.1 to 15.0% by weight of at least one cationic surfactant, and 0.1 to 15.0% by weight of at least one saturated or unsaturated, branched or unbranched C.sub.8-C.sub.30 alcohol and/or a saturated or unsaturated, branched or unbranched C.sub.8-C.sub.30 carboxylic acid and/or a salt of a saturated or unsaturated, branched or unbranched C.sub.8-C.sub.30 carboxylic acid, as well as production and application methods and uses thereof.
