COMPOSITIONS AND METHODS FOR PROTECTING HAIR FROM CHEMICAL AND THERMAL DAMAGE

摘要

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.
