Androgenic alopecia is the single most common form of hair loss. 50% of men over age 50 are affected by androgenic alopecia. 50% of women over age 65 begin developing androgenic alopecia. The enzyme 5-alpha reductase converts free testosterone into DHT, which then miniaturises genetically susceptible hair follicles until they cease producing visible hair. In androgenic alopecia, follicular units progressively atrophy — the number of hairs per unit decreases and individual hairs become finer before scalp becomes visible.
