Analysis of Changes in Hair Color caused by Mixing Hair Dye in Three Primary Colors

Hairstyles can be created by various treatments such as haircut, perm, coloring and bleaching. In particular, hair colors can vary depending on circumstance, place, season, feeling, mood and image. This study targeted to learn how to mix hair dyes to create wanted color with a better understanding of the mixture of hair colors and prove the acquisition of wanted color. For this, the followings were analyzed through a theoretical review: hair coloring, types and characteristics of hair dyes, characteristics of melanin pigments, color charts of ‘W’. In terms of an empirical study, color changes by ratio according to hair dye levels were derived. The acquired hair dyes were applied to white hair and black hair, and a total of 90 different colors were obtained. The test results found the followings: First, ‘45(R)’ and ‘88(B)’ were mixed in a 1:1 ratio, it was unable to create ‘6 (purple)’. When ‘88(B)’ and ‘/3(Y)’ were mixed, the secondary color of ‘/2(green)’ in the color chart wasn’t expressed. In fact, it was close to ‘/11(ash gray)’. When ‘/45(R)’ and ‘/3(Y)’ were blended, the secondary color of ‘/44(orange)’ in the color chart was ‘level 12’. When they were mixed in the ratio of 3 to 1, the color was closest to ‘12/44’. In other words, when hair dyes are mixed, color gets darker when hair dyes with strong color are used than when they are mixed at a certain ratio. In black hair, hair color does not change much by a mixing ratio. In fact, brightness can only be classified based on the existence of redness. It’s hoped that the study results would help hairdressers understand the standards of color changes by the mixture of hair dyes and establish the grounds for consulting hair coloring through the development of a color chart.
