Male pattern baldness can begin in men as young as 25yrs. This is characterised by hair thinning from the sides of the forehead (receding hairline). The Norwood-Hamilton scale of male pattern baldness
 Receding hairline is usually followed by an additional bald patch on the top of the head (vertex). Most pattern baldness is genetic; there is some research that both parents contribute to their son’s likelihood of hair loss. We know that the trigger for hair loss is a powerful hormone, DHT. The mechanism by which DHT causes hair loss in males is not fully understood but it is thought that DHT causes miniaturization of the hair follicle; the hair shaft width is progressively decreased until the scalp hair resembles fragile ‘downy’ hair or becomes non-existent. The psychological effect on individuals vary widely, some men find it difficult to accept their new body image and others prefer to completely shave their head, and wear their new look as a fashion statement.

Approximately 25% of men begin balding by the age of 30 and 65% by the age of 60. |
