Female androgenetic alopecia belongs to the family of scar-less, diffuse, telogenic, hormonally determined alopecias with hereditary disposition. In the androgenetic alopecia, progressive, androgen mediated miniaturization of genetically predestined hair follicles develops. Genetic factors play a role namely in females without the higher serum androgen level. Pathologically high level of serum androgens is usually accompanied with signs of virilization. Hair dropping starts in the fourth decade or earlier. It occurs in the postmenopausal period, after a pregnancy, after the onset or termination of peroral contraception, in women treated by aromatase inhibitors.
