Androgeneic alopecia is essentially the male equivalent of Polycystic Ovary Syndrome (PCOS). It is a common disorder found among women and caused by hormonal disorder. There is a genetic and biochemical relation between Premature Balding and PCOS.

The symptoms of PCO
Women suffering from PCOS show the following symptoms -
  • Hirsutism or excess body hair growth
  • Balding
Hormones responsible for PCOS
DHT and testosterone are responsible for PCOS. DHT is responsible for stimulating growth of body hair follicles and also causes scalp hair loss.

Testosterone induces body hair growth, but it is not true with scalp hair. Too much sensitivity of hair follicles to tesosterone results in balding.

Genetic relationship between premature balding and PCOS
Studies show that there is a genetic predisposition to premature balding in men who are siblings of PCOS-affected women. The occurance of PCOS in families is long established.

A separate hormone profile study provided substantial evidence that the hormonal pattern of men with premature balding resembles in some respects the hormonal pattern of PCOS affected women.

Excess androgen level among women
In women having excess androgen levels, the very fine body hairs will turn into coarse, dark hairs on the abdomen. The latter will grow on the navel and also on the face. And those women having predispositon to baldness will also grow the same.

Extremely high testosterone levels will cause baldng, even without the presence of any genetic predisposition.
