title: Scanning electron microscopy of hair. Observations on surface morphology with respect to site, sex and age in man.
abstract: The cuticular scale pattern of adult human terminal hair sampled from  10 different body sites was examined by scanning electron microscopy and showed: (1) differences according to site, the size of the cuticular scales being significantly greater in scalp hair than in hair taken from the nine other sites; (2) differences according to sex, the size of cuticular scales of facial, axillary and abdominal hairs being significantly larger in females; and (3) differences according to age, the size of cuticular scales from scalp hairs being significantly smaller in older than younger people.
