Baldness is due to the reduction of hair follicles that produce hair is shorter and softer. The end result of this situation is a very small hair follicles, which do not have hair.
The cause of the failure of new hair growth is not fully understood, but it is related to heredity and hormones androgens, primarily dihydrotestosterone from testosterone.

Male pattern baldness begins at the hairline, gradually, the hairline back form letter M.
Hair becomes finer and does not grow along earlier.
The hair on the crown also begins to thin and eventually the top end of the M-shaped hairline met with a thinning crown, forming a horseshoe-like hair loss.

There are two types of drugs used to treat male and female pattern baldness are minoxidil and propesia.

Propesia inhibit the formation of hormones that play a role in the occurrence of baldness. This drug is more effective than minoxidil and no effect on serum testosterone in the body.

Hair transplantation is done by lifting a small collection of hair from areas where hair is still growing and place them in areas experiencing baldness.
This can cause the formation of scar tissue in the donor area with a low risk of infection.
This procedure may be performed repeatedly and is expensive.
