Hormonal status in postmenopausal androgenetic alopecia.

Androgenetic alopecia or pattern hair loss is thought to be caused by increased androgen action on hair follicles with menopause. Testosterone, estradiol and sex hormone binding globulin (SHBG) serum levels were determined in ten postmenopausal women with pattern hair loss and in ten sex and age matched healthy controls. No statistically significant differences were found in the hormone levels between the patients and the controls. These findings suggest that a genetically determined functional alteration of androgen receptors and/or a metabolic disturbance may exist in the hair follicle keratinocytes in pattern hair loss.
