For the study that these problems are basic this study mixed the thioglycolic acid and cysteine which are usually used as processing solution along with the appropriate ration to compare and analyze the dynamic property in virgin hair(V-HR), coloring hair(C-HR) and bleaching hair(B-HR) following the wave formation of the hair with the following conclusion. Curl formation of hair all appeared greatly virgin hair, coloring hair, bleaching hair according to increase of content ratio of thioglycolic acid. Bleaching hair has the lease of gloss compared to other waves, and the quality of entire hair is loosened with narrow wave width. However, it has the largest wave formation than virgin hair or coloring hair. The virgin hair which an exposure does not become to a medication regardless of mixing ratio rates of a permanent processing solution curl wave formation dropped than coloring hair, bleaching hair. Therefore, in order to give the wave of healthy hair, it is advantageous to use the thioglycolic acid agent; and in case of the damaged hair, it would be more prudent to use the cysteine agent. In general, it is known that the damage of hair is greater when applying the thioglycolic acid perm than that of applying with the cysteine perm. However, the change rate of dynamic property results tensile strength of hair and the coefficient of expansion a large difference was not after coating with a permanent processing solution at regular mixed ratio on sample ore hair. However, did not operate, and permanent showed with a large difference in comparison with control. Therefore, generate a lot of problems, and a chemical process of a way of permanent surgical operation and virgin hair is thought to healthy hair management. In experiment of this study, the sample hair is limited to one person and the type of perm and the number of application have the limitation in one application; however, it is hoped that, with this study as the foundation, more specialized and expert data would continuously established under the various working conditions. |
