A hair strengthening 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 denaturation thermal energy is increased, and there is no damage to hair of the type characteristic of heat and chemical treatments.
L'invention porte sur une composition topique de renforcement capillaire comprenant des matières émettant un rayonnement électromagnétique à des longueurs d'onde affectant des liaisons à structure tertiaire (rupture de pont disulfure) dans les cheveux humains, et provoquant des changements de structure secondaire des protéines de 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 l'énergie thermique de dénaturation des cheveux est augmentée, et qu'il n'y a pas de dommage du type caractéristique des traitements thermiques et chimiques apporté aux cheveux.
