다국어 초록 (Multilingual Abstract)

The purpose of this study is to present a treatment method that is more effective and reduce hair damage, by measuring a scale state, physical damage, and color changes in hair given simultaneously operating the perm and the decoloration. A sample, which was utilized in this study, was used 200 strands by 10㎝ each as the hair, which hadn`t been performed the beauty treatment by chemicals for more than 1 year, targeting 5 healthy women in their 20s. After setting to 25±1℃ in temperature and to 50±10% in humidity, the scale was observed with×1000 magnifications by using Scanning Electron Microscope(Hitachi S-2500). Thickness measurement was used Nikon, MM-60/L3T. The load measurement was used Instron, 4482-standard. Color-tone level measurement was used Color Techno System, JP/JX-777. And then, the values in brightness, color, and chroma were analyzed by measuring Lab value, Yxy value, and CMYK value within the visual field of illuminant C 2°. The statistical processing was calculated average and standard deviation in the measurement value by using SPSS 12.0 statistical program. And, t-test and ANOVA were carried out. The following are the results on a change in hair in the de-coloring treatment after perm and in the perm treatment after decoloration. As a result of observing scale, the hair with the de-coloring treatment after perm was small in damage in light of being less broken in the scale form and less even in dissolution, compared to the hair with the perm treatment after decoloration. In the physical damage, the hair with the de-coloring treatment after perm was indicated to be a little better in maintaining intensity. In the stylistic level in wave, the significant difference was not indicated between the two treatment sequences. As a result of examining Lab value and Yxy value that show the color in hair, all showed significant difference. The hair with the de-coloring treatment after perm was indicated to be wholly high in Lab value, Yxy value, and CNYK value. And, in brightness, color, and chroma, it could be seen to be decolored into the brighter and clearer color. Accordingly, given the de-coloring and perm treatment at the same time, a case of being addressed the perm treatment before decoloration was less in hair damage and was excellent in an effect of decoloration.
