Silicon bags are inserted beneath an area of hairy scalp and gradually inflated with saline water over a six-week period. This causes the hair-bearing skin to stretch, thus increasing the amount of hair-bearing scalp. After removing the bags, expanded hair bearing skin is lifted and moved to an adjacent bald area where a similar sized patch of scalp has been excised. Finasteride (Propecia). This prescription medication to treat male-pattern baldness is taken daily in pill form. Many people taking finasteride experience a slowing of hair loss, and some may show some new hair growth. Positive results may take several months. Finasteride works by inhibiting the conversion of testosterone into dihydrotestosterone (DHT), a hormone that shrinks hair follicles and is an important factor in male hair loss. Rare side effects of finasteride include diminished sex drive and sexual function. As with minoxidil, the benefits of finasteride stop if you stop using it. In the hands of well-trained and experienced physicians, and using newer techniques with smaller grafts, the hair grows in the proper direction with a feathered hairline, and a highly aesthetic result. Hair transplantation can be done both on patients with advanced baldness and earlier thinning. Newer treatments for men like Propecia or for both men and women, like Rogaine should be considered as well especially in patients with earlier thinning as these medications often slow significantly the progression of hair loss. In general, hair transplantation is not considered for patients younger than their mid 20s because of difficulty in predicting ultimate extent of hair loss.
