The hair loss of male pattern baldness is permanent. No treatment is required if the person is comfortable with the appearance.
There are two drugs approved by the United States Food and Drug Administration (FDA) to treat male-pattern baldness: minoxidil and finasteride (Propecia).
Minoxidil is used topically on the scalp. It may help hair to grow in 20 to 25% of the population, and in the majority it may slow the loss of hair. Treatment is expensive, however, costing about $600 per year for the recommended twice-daily use. The higher concentration minoxidil works better. Hair loss recurs when its use is discontinued.
Finasteride is the only oral medication that is approved by FDA for male pattern baldness. It inhibits the production of the hormone that contributes to male pattern baldness. About 50% of men who take this drug have increased hair growth in one year. In general, it is more effective than minoxidil. It has no major effect on testosterone level in the body. About 2 percent of the men who take this drug experience sexual dysfunction.
Hair transplants consist of removal of tiny plugs of hair from areas where the hair is continuing to grow and placing them in areas that are balding. This can cause minor scarring in the donor areas and carries a modest risk for skin infection. The procedure usually requires multiple transplantation sessions and may be expensive. Results, however, are often excellent and permanent.
Suturing of hair pieces to the scalp is not recommended as it can result in scars, infections, and abscess of the scalp. The use of hair implants made of artificial fibers was banned by the FDA because of the high rate of infection.
Hair weaving, hairpieces, or change of hairstyle may disguise the hair loss. This is usually the least expensive and safest treatment for male pattern baldness.
