| Abstract |
|
In this study, methylene blue (MB) staining method to determine the state of hair damage was established. For this purpose, the characteristics of absorption or desorption of MB by bleached hair was studied and hair damage index(HDI), an index indicating the degree of hair damage was proposed. According to the experimental results, HDI values were found to be increased as the bleaching time or numbers were proportionally increased and this was confirmed again by determining the tensile strength(TS) of damaged hairs or by observing them with scanning electron microscope. HDI and TS was inversely proportional with repeating numbers of hair bleaching and the correlation coefficient of them was found to be 0.9078. When the hair was purposely damaged with various hair styling methods, the HDI was increased in the order of volume magic straight perm, bleaching and dying, and heat perm. From these results, the MB method may be employed as a useful method to determine the degree of hair damage. |
