Male pattern hair loss is a common condition in which men experience thinning of the hair on the scalp. These changes typically begin gradually in men in their 20's.
Doctors believe male pattern hair loss is due to heredity and is dependent on hormonal effects.
Doctors studied over 1800 men aged 18 to 41 with mild to moderate amounts of ongoing hair loss. Although results will vary, generally you will not be able to grow back all of the hair you have lost. Male pattern hair loss occurs gradually over time. On average, healthy hair grows only about half an inch each month. Therefore, it will take time to see any improvement.
