• Finasteride (Propecia): This is a prescription drug for men. You take it daily as a pill. Many men taking finasteride experience a slowing of hair loss, and some may show new hair growth. It may take a few months to tell whether it's working for you. You'll need to keep taking it to retain any benefits. Finasteride may not work as well for men over 60.
• Other medications: Other oral options include spironolactone (Carospir, Aldactone) and oral dutasteride (Avodart).
Hair transplant surgery:
In the most common type of permanent hair loss, only the top of the head is affected. Hair transplant, or restoration surgery, can make the most of the hair you have left.
During a hair transplant procedure, a dermatologist or cosmetic surgeon removes hair from a part of the head that has hair and transplants it to a bald spot. Each patch of hair has one to several hairs (micrografts and minigrafts). Sometimes a larger strip of skin containing multiple hair groupings is taken.
Laser therapy:
The Food and Drug Administration has approved a low-level laser device as a treatment for hereditary hair loss in men and women. A few small studies have shown that it improves hair density. More studies are needed to show long-term effects.
