A rule of level in lightness combination of oxidation hair color
ABSTRACT
There search which sees examines hair lightness changes of hair coloring one after that in compliance with lightness combination of oxidation hair color. The testing method did, crossroads low lightness(1∼4Level; LL), middle lightness(5∼7Level; ML) and hight lightness(8∼10 Level; HL) combination mixed experimented at ratio of the 3:1, the 2:1, the 1:1, the 1:2 and the 1:3. The result of experiment according to mixture ratio analyzed the ratio price of the 1:1 in standard. Result of analysis, oxidation hair color from “ML+HL” lightness combination standard deviation average difference did not appear almost below 0.5. Standard deviation average difference of above 0.5 appeared from “LL+ML” and “LL+HL” lightness combination. Therefore oxidation hair color of low and hight lightness are combined and the possibility in case the ratio which is mixed is many of affecting high in lightness of the hair is the thing is conclusion. Consequently lightness, combination of oxidation hair color uses combination according to lightness difference where does the possibility of knowing lightness scope will be able to rise with being, combination of oxidation hair color will be able to present the standard which does.
