A hair shaping topical composition comprising materials that emit electromagnetic radiation at wavelengths that affect tertiary structure (breaking of disulfide) bonds in human hair, and that bring about changes in secondary structure of hair proteins. The intensity of the radiation is controlled and sufficient to cause or facilitate altering of protein structure. The invention includes methods of using such topical compositions. Testing indicates that the hair reshaping is permanent and there is no damage to hair of the type characteristic of chemical treatments.
L'invention porte sur une composition topique de mise en forme des cheveux, comprenant des matières émettant un rayonnement électromagnétique à des longueurs d'onde affectuant les liaisons de structure tertiaire (rupture de pont disulfure) dans les cheveux humains, et provoquant des modifications de structure secondaire des protéines des cheveux. L'intensité du rayonnement est commandée et suffisante pour provoquer ou faciliter l'altération d'une structure protéique. L'invention comprend des procédés d'utilisation de telles compositions topiques. Un test indique que la remise en forme de cheveux est permanente et qu'il n'y a aucun dommage caractéristique des traitements chimiques apporté aux cheveux.
