Hair dye composition

Abstract

Abstract PURPOSE:To minimize reduction of touch of hairs due to hair-dyeing treatment and keep especially stiffness and nerve by blending a hydrolyzed protein and amino acid derivatives with an acidic hair dye. CONSTITUTION:This hair-dye composition is composed of an acidic hair dye ready to use, a hydrolyzed protein and an amino acid or its derivative and can be used in the form of one pack type hair dye. As the hydrolyzed protein, one or more kinds of substances selected from a hydrolyzed keratin protein, a hydrolyzed collagen protein, a hydrolyzed silk protein and a hydrolyzed elastin protein are preferably used. A hydrolyzed keratin protein is especially preferably used. In addition, as the amino acid or the amino acid derivative, glycine, alanine, valine, leucin, serine, threonine, phenylalanine, tyrosine, aspartic acid, asparagine, cysteine, histidine, arginine, glutamic acid, pyrrolinecarboxylic acid or their salt is preferably used.
