Abstract

Human hair is a kind of fibrous keratin which has much cystine residues like wool fiber. It protects human head from the dangerous shock and is an organ to relase heavy metal in human body. Recently, in many dyeing field there is a trend to utilize the natural dyes. Safflower is a reddish natural mordant dye. When the safflower is applied in human hair dyeing, it is expected that dyeing rate will be slow and wash fastnss will be poor on account of large molecular weight relative to oxidative dyes. In this work, we investigate the effects of benzyl alcohol in hair dyeing with natural dye saffolwer. Dyeability of hair increased significantly by adding benzyl alcohol in safflower dyeing. Neverthless the hair was slightly damaged during dyeing, the dyed hair showed a good wash fastness.
