The purpose of this study is to examine the possibility of betacyanin pigments of beet, 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, betacyanin concentration was analyzed by measuring absorbency from betacyanin 540 nm of beet. Unmordanted hair dyeing was increased in dye intake(K/S) with increased dyeing time(20min∼60min) and hair color was changed from red to purple. Increased dyeing hours were associated with decreased lightness(L*) and yellowness(b*). Increased dyeing hours were associated with increased dye intake(K/S) and redness(a*). It suggested that changes in lightness and a* were one of determinants of dyeing hair color.
