Hydrogen peroxide used for hair bleaching and permanent wave as oxidants in cosmetics. So that, in this study, the improvement effect of hair bleaching was investigated by electrolyzed acid and alkalic water treatment under different hydrogen peroxide condition. In thereslut, it was found that in hair treated in 10-minutes bleaching, the hair pre-treated with electrolyzed alkalic water had high brightness,in hair treated in 15-minute bleaching, the brightness of the hair pre/post-treated with electrolyzed water was the highest, and hair treatedin 10-minute decoloring agent after pretreatment with electrolyzed alkalic water had higher brightness than that of hair treated in 15-minute bleaching. The pieces with thick hair and higher tensile strength were the pieces of hair treated with decoloring agent for 10minutes and the ones pre/post-treated with electrolyzed water; it was indicated that the hair which had long reaction time for decoloringagent and the hair pre-treated with electrolyzed alkalic water became thinner, and their tensile strength weakened. As the degree of waters welling and alkali solubility were the lowest in the hair pre/post-treated with electrolyzed water, followed by the hair treated with decoloring agent and the hair treated with electrolyzed alkalic water, it was observed that reaction time for decoloring agent and the treatments with electrolyzed alkalic and acidic water had effect on the damage of hair. The cuticle of the hair pre-treated withelectrolyzed alkalic water was thick, the thickness of cuticles of hair treated with decoloring agent and the one post-treated with electrolyzed acidic water were found to be thin, and the morphological change in the cuticles and their damages were observed to bealmost same. Thus, it was proved that pre/post-treatment of electrolyzed water enhanced the bleaching effect of hydrogen peroxide and minimized damage of hair. |
