The surface properties and the tactile texture of human hair are important in designing hair-care products. In this study, we evaluated the temporal changes of friction and temperature during the drying process of wet human hair containing water, silicone oil, or oil-in-water (O/W) emulsion. The wet human hair including water or O/W emulsion have a moist feel, which was caused by the temperature reduction of approximately 3-4°C. When human hair is treated with silicone oil, more than 60% of the subjects felt their hair to be slippery and smooth like untreated hair. Treating hair with O/W emulsion after drying made the subject perceive a slippery feeling because the surfactant reduced friction on the hair surface. These results indicated that both friction and thermal properties of the hair surface are important to control the tactile texture of the human hair.

We evaluated the friction properties of five cosmetic sponges on artificial skin using sinusoidal motion-friction evaluation system. No significant difference was observed in the pleasant score of the five sponges when these sponges were rubbed on the skin surface. The sponges were classified into three groups based on their tactile feel. Their characteristic tactile textures were moist-soft-slippery, moist-dry-rough, and moist feels. The slippery feel was found to depend on the thickness of the sponge’s cell wall, its surface tension, and the change in friction coefficient in the dynamic friction process. These findings are useful in the design of cosmetic sponges.
