description The present invention provides a protein-silane and/or protein-siloxane copolymer obtainable by reacting a protein and a silane compound, the relative amounts of the protein and the silane compound being such that in the range of from 0.1 to 0.4 silane molecule is present for each reactive amino group of the protein. The copolymer is suitable for use in hair treatment compositions and is useful in reducing damage to hair caused by flexure and/or abrasion thereof. La présente invention concerne un copolymère de protéine et de silane et/ou un copolymère de protéine et de siloxane qui peut être obtenu par réaction d'une protéine et d'un composé de silane, les doses relatives de protéine et de composé de silane étant telles que de l'ordre de 0,1 à 0,4 molécule de silane est présente dans chaque groupement amine réactif de la protéine. Le copolymère est approprié pour être utilisé dans des compositions de traitement capillaire et permet de réduire les agressions subies par les cheveux provoquées par flexion et/ou par abrasion.
