In this study, the hair damage mitigation effects when applying the Bombyx mori powder, Bombyx mori oil, which are the natural extracts, commercialized argan oil, LPP, and sodium glutamate to the damaged hair in the alkaline dyeing procedure, which is the chemical procedure, were observed and following results were drawn. In the results of observing the cuticle, it was observed that adding the Bombyx mori powder and the Bombyx mori oil, which contain abundant protein, was effective, and the experiment group, which represented the similar brightness to the control group was the group applied with the Bombyx mori oil. In the tensile strength measurement, which the degree of hair damage can be observed, the argan oil, which is the natural vegetable oil, represented the highest tensile strength, and the sodium glutamate, which is the artificial flavor, represented the lowest tensile strength. In the results of observing the amino acid composition change, the adding the Bombyx mori powder and Bombyx mori oil, which contain rich protein, and the sodium glutamate, which is composed of 95% of amino acid, represented the highest amino acid composition value. As a result, the Bombyx mori powder and the Bombyx mori oil, which are the natural extracts, is deemed to be the effective application to be able to reduce the damage not by the pre-treatment nor post-treatment but by adding in the hair colorants in the damaged hair dyeing procedure.
