USE OF THE COMBINATION OF AMINO ACIDS HAVING AN ALIPHATIC SIDE CHAIN AND HAVING A BASIC SIDE CHAIN IN TOPICAL HAIR TREATMENT

摘要

The use in a topical hair treatment composition, such as a shampoo or conditioner, of a combination of (i) an amino acid having an aliphatic side chain; and (ii) an amino acid having a basic side chain for the repair and/or prevention of split ends in hair. Isoleucine is the most preferred amino acid (i) for the use according to the invention. Lysine is the most preferred amino acid (ii) for the use according to the invention. The combination of amino acids (i) and (ii) has a beneficial synergistic interaction with respect to the repair and/or prevention of split ends in hair, which significantly exceeds the efficacy of either class of amino acid when used in isolation at the same levels or even at higher levels.
