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. All hair pieces were faded after 30-times shampoo, especially oxidizing colorant treated hair piece was the strongest. Not only thickness and cuticle thickness of hair shafts in henna treated hair shafts and 3 kinds of black rice treated hair shafts before and after 30-times shampoo were thicker, but also tensile strength was stronger compare to oxidizing colorant treated hair shafts. Damage of cuticles showed heavier in oxidizing colorant treated hair shaft than that of henna and 3 kinds of black rice extracts.
