The purpose of this study is to examine the possibility of anthocyanin pigments of Mulberry, which is natural hair dye and free from skin irritation and environmental pollution, as hair dye to make up for the limitations of natural hair dye such as simple color and unscientific process of hair dyeing. In order to achieve this purpose, anthocyanin concentration was analyzed by measuring absorbency from anthocyanin 520 nm of Mulberry. Using FeSO4, KAl(SO4)2, CuSO4 and H3COOH that are mordants, mordanting effects were measured, compared, and analyzed for hair dyeing to suggest standardized conditions to make various colors. 1000㎖ extracted mulberry juice was dipped in 9000㎖ ethanol, 950㎖ distilled water and 50 ㎖ HCl) and left for 24 hours at room temperature to extract pigments. The extracted solution was used to measure the absorbance within 400～700nm spectrum range. As a result, the maximum absorption wavelength was found at 520nm. To implement diverse colors in hair dyeing, FeSO4, KAl(SO4)2, CuSO4 and CH3COOH were used as mordants. FeSO4 showed mordant effects with the a* value minutely progressing to -(green) and the K/S increasing. Similarly, CuSO4 showed green dyeing effects with much color difference and the a* value substantially progressing to -(green). When using the undiluted mulberry juice directly applicable to beauty treatment, compared with the extracted anthocyanins, the a* value was lower but the K/S was found very high, indicating reddish hair dyeing effects.
