Testosterone inactivates hair follicles on the scalp, while it stimulates hair follicles on the face and elsewhere on the body. These effects are obvious in men: Higher testosterone levels give less hair on the scalp and more on the body. Testosterone has the same effects in women.

Testosterone also makes the skin and scalp more oily and may also trigger acne.

Androgenic Alopecia is extremely common. It is estimated that it affects as many as 50% of men. The prevalence in women is reported to be up to 20% prior to menopause, while it increases to more than 40% after that, and, according to some, it may affect as many as 75% of women older than 65 years.

Androgenic Alopecia causes a progressive thinning or loss of hair, which may develop slowly over years. It generally does not effect children or teens, but may occur any time after the age of 20.

Androgenic Alopecia sufferers often have a family history of hair loss, but also people without a family history can be affected.
