毛发和皮肤的摩擦和磨损特性的表征对于开发更好的洗发水和护发素产品以及推进生物和化妆品科学至关重要。迄今为止，关于毛发和皮肤的摩擦学表征的文献很少。在这项研究中，摩擦实验进行了一系列的负载，速度和皮肤面积，以研究它们对皮肤-头发接触的影响。此外，进行摩擦和磨损实验以模拟标称条件下的皮肤-毛发和毛发-毛发接触。研究了温度和湿度对毛发与皮肤摩擦力的影响。使用平对平摩擦计在往复运动下对高加索人、亚洲人和非洲人的毛发（原始的、化学机械损伤的和调理剂处理的）相对于聚氨酯膜（合成皮肤）和相对于毛发进行测量。用原子力显微镜和光学显微镜观察毛发和皮肤的形态。测量每个种族和头发类型的平均摩擦系数值，并进行了讨论。还讨论了摩擦力与头发的方向性关系。(c)2005 Elsevier B.

Characterization of friction and wear properties of hair and skin is essential to develop better shampoo and conditioner products and advance biological and cosmetic science. Literature on the tribological characterization of hair and skin is scarce to date. In this study, friction experiments were performed at a range of loads, speeds, and skin area in order to study their effect on skin-hair contact. In addition, friction and wear experiments were performed to simulate skin-hair and hair-hair contacts at nominal conditions. Environmental dependence of hair friction is of importance and the effects of temperature and humidity on the friction of hair against skin were studied. Measurements were made using a flat-on-flat tribometer under reciprocating motion on Caucasian, Asian, and African hair (virgin, chemo-mechanically damaged, and conditioner treated) against polyurethane film (synthetic skin) and against hair. The morphology of hair and skin were measured by atomic force microscopy (AFM) and optical microscopy. Average coefficient of friction values were measured for each ethnicity and hair type, and are discussed. The directionality dependence of friction with respect to hair is also discussed.
