THE SORPTION OF AMINO ACIDS FROM SHAMPOOS ON TO HAIR 277 The difference between the two groups of sub-tresses is significant at a level of just above 1 per cent. CONCLUSIONS These results show that amino acids, and presumably peptides, can be deposited on hair from a shampoo solution. The same shampoo solution will also remove some of the previously deposited amino acid from the hair. The amount remaining on the hair after shampooing will thus depend on the amount present on the hair initially and the concentration of the amino acid in the shampoo. It is reasonable to presume that similar results would be obtained in the case of the keratinous epidermis and that some amino acids would be left on the scalp after washing the hair with a shampoo containing amino acids, though this has not been attempted experimentally for obvious reasons.
