This study attempted to investigate the improvement and hair protection effects of damaged hair by applying wild peach leaf extract-added treatments P0 (no addition), P5 (5%) and P10 (10%) during Pigmentation Techniqu hair dyeing, and to verify its applicability as a natural material. To this end, tensile strength of hair, hair cross-section observation using SEM, hair thickness (interruption), hair epidermis thickness using FE-SEM, and hair gloss were measured. As a result of the experiment, it was confirmed that the higher the concentration of wild peach leaf extract, the higher the tensile strength, hair cross-section, hair thickness, hair gloss, and hair improvement and hair protection effects (P0 > P5 > P10). Therefore, it is judged that it is highly likely to be used as a material for nature-friendly hair cosmetics. It is hoped that the development and research of hair cosmetics using various natural extracts will be carried out in the future.
