Seven hair pieces were divided for normal, bleaching and treatment with oxidizing colorant, henna and 3 kinds of blackrice. Hair pieces and shafts of all pieces were measured color value, thickness and tensile strength and observed change of hair cuticles` structure before and after 30-times shampoo. As the result, the color revealed rose in oxidizing colorant treated hair piece, matt khaki in henna treated hair piece, red-violet in balck rice ethanol extract treated hair, bright red-violet in balck rice ethanol extract and acid treated hair, ash brown in black rice ethanol extract and alkali treated hair.
