Hairs have a number of functions including thermoregulation, collecting sensory information, protection against environmental trauma, social communication and mimicry. The hair is altered and changed such as weakness of tensile strength, alopecia and canities by physical and environmental factors. In this study, the physicochemical properties and morphological change of in altered hairs were investigated in 24 spenders of adulthood and elderly. Thickness, tensile strength, water swelling and alkali solubility, breadth and thickenss of hair cuticle were measured and morphological change of cuticle and cortex were observed. In the result, thickness and tensile strength of hair as aging indicator decreased significantly in elderly men and women in contrast to adulthood (p<0.05), and both parameters were higher in men than in women of adulthood and elderly. Breadth and stepping of cuticle decreased in elderly men and women in contrast to adulthood. But water swelling and alkali solubility as hair damage indicators increased in elderly men but not women. More damaged cuticles and diffuse melanin granules appeared in elderly than in adulthood by SEM and TEM observation. In conclusion, aging induced to change of physicochemical properties and morphology, and decreased hair thickness in elderly men and women may be not decreased thickness of cuticles but loss of cuticle layers.
