Abstract

Various studies have been conducted on the development of products which can minimize the damage of hair permanent and this study experimented improvement effect of natural material bentonite on damaged hair. To test wave-forming power, damaged hairs were divided into group DT and group DC and group DT used thioglycolate while group DC used cysteine in the ratio of 8:2, 6:4, 5:5, 2:8. To measure tensile strength and form, healthy hair used thioglycolate as group VC and VE, and damaged hair used cysteine as group DCand DE. As the result of the test, wave-forming power was the biggest in 8:2 ratio and tensile strength of experimental group increased minimum 8% to maximum 19% with low flaking phenomenon on cuticle of the experimental group, showing that it can improve damaged hair of the customers with permanent wave in the long term. To prevent precipitation of bentonite, frequent shaking is required and winding treatment must be done quickly. If these problems are improved in the development of the products, they can be more generalized for the customers who are worried about chemical treatment due to their damaged hair.
