Recently. dyeing by harmless natural materials has received much attention due to the side-effects occurred from dyeing by synthetic dyes. In this study, we examined the effect of extracts of Pueraria thunbergiana (P. thunbergiana) roots, which are treated as natural products as well as agricultural wastes, on the hair dyeing by measuring dyeing interval, temperature, density changes, mordant and chromatic faction. The hair dyeing by the extracts significantly reduced hair damage and kept cuticle of hair softer than that by synthetic dyes. In addition, since a mordant is one of the necessary additives in dyeing, the role of a mordant was studied and concluded to be a supplementary substance based on the results that the hair dyeing by the extracts of P. thunbergiana roots alone was much darker than the others. Taken together, the data presented in this study suggest that the extracts of P. thunbergiana roots are is less damageable to hair and thus can be more safely applicable to hair dyes than that by synthetic dyes.
