This paper conducted a study as to how damaged hair quality was Improved not only by washing effect with a produced shampoo but also by measuring tensile strength, contents of amino acid and absorbance of hair washed with a shampoo produced by amino acid. The result of absorbance analysis indicated that the shampoo improved the level of damages on hair as its measurement value was lower than a plain shampoo. As analysis of amino content, the hair damage was reported to be improved as the content of amino acid on hair painted with the shampoo was a little increased. As the result of tensile strength test, hair damage was reported to be improved as tensile strength was improved when hair was washed with a shampoo. From the results mentioned above, when people’s hair was washed with a shampoo whose main ingredient was amino acid, it’s proved that there was an effect for improving damaged hair caused by dyeing and bleaching operation. As a shampoo made of amino acid could be produced and used for experts in hair shops, its commercialization value was believed to high.
