The Study on the Chromaticity Change of Acid Coating Hair-dyeing Products by Shampoo Treatment

  In this paper, to investigate chromaticity change of acid-coloring hair dye by shampoo number of times, we measured chromaticity change on the domestic brand company"s products(Amos, Shinsung, Sarangsae). In the case of red color, SR co. was shown both lightness index(L*) and chromaticity index(a* and b*) big change while A co. and SS co. were very stable. In the case of yellow color, while lightness index(L*) and red-chromaticity index(a*) were seldom shown big difference, yellow-chromaticity index(b*) was shown big change. In the case of blue color, while SS co. and SR co. were very stable, a lightness index(L*) and yellow-chromaticity index(b*) of A co. altered greatly. In the effect for color space by products, A co."s chromaticity change was not big, and SS co"s a little change, SR co."s in red color and yellow color big change. Through the study of chromaticity change of acid-coloring hair dyeing product by shampoo number of times, could grasp tendency of chromaticity change by products and colors for domestic brand"s products.
