Purpose: The purpose of this study is to examine the possibility of natural hair dyeing using anthocyanin pigments from blueberries.
Methods: The hair dyeing and color change of blueberry extracts were measured at the maximum absorption wavelength of anthocyanin by varying dyeing temperature, dyeing time, and pH. Several mordants were used, and the mordanting effects and colorfastness were investigated in accordance with the mordanting method and mordant concentration.
Results: The maximum absorption wavelength of anthocyanin in the blueberry extracts was 520 nm. As the dyeing temperature and dyeing time increased, the dye uptake (K/S) increased and lightness (L* ) decreased; the K/S were in the 21.639?58.968 range. The most effective condition for hair dyeing using anthocyanin pigments was 40°C for 40 min. Anthocyanin pigments are especially sensitive to pH, and K/S decreased with increasing pH. It was found that the redness (a*) increased in acid and the yellowness (b*) increased in alkali. Based on the K/S value only, pre-mordanting was effective for FeSO4, MgSO4, MnSO4, CuSO4, CH3COOH, Co(NO3)2, CaCO3, and Na2CO3, and post-mordanting was effective for AlK(SO4)2. The changes of K/S values at mordant concentrations were 69.665 for 1% FeSO4 and 59.515 for 5% and 15% CuSO4. AlK(SO4)2 and Co(NO3)2 showed high K/S changes of 66.555 and 63.127 at 20%, respectively. The colorfastness to washing was decreased with repeated shampooing. The K/S was in the 46.333?21.098 range, and the K/S difference was 16.911 after washing.
Conclusion: Extracts from blueberries may be useful to be used as a hair dye.
