Causes
Male pattern baldness is related to hormones called androgens, specifically an androgen called dihydrotestosterone (DHT). It attaches to receptor cells on the scalp and hair follicles, interrupting and interacting with the normal mechanics involved with continual, healthy hair growth. Men whom display male pattern baldness typically have lower levels testosterone, but a proportionately higher level of DHT in their body. Other factors such as lifestyle factors and terminal illness may cause hair loss as well.
Symptoms
The most notable symptom of the onset of male pattern baldness is hair loss along the hairline that gradually recedes into an “M” shape. The hair at the crown begins to thin, eventually meeting the receding hairline and creating a horseshoe pattern of hair around the sides of the head. Male pattern baldness is typically diagnosed by the appearance of this pattern. Other diseases such as alopecia areata or folliculitis may cause dissimilar balding patterns and should not be diagnosed as male pattern baldness.
Treatment
Medicinal treatments for male pattern baldness include Propecia and Rogaine. Both are more successful at slowing hair loss than exhibiting new hair growth. Needless to say, unlike hair transplantation as offered by companies like Bosley, no medicinal treatment is a permanent solution for male pattern baldness. Of the two, Propecia is most successful with male pattern baldness as it inhibits the growth of DHT androgens. Take a look at the Propecia and Rogaine sections on BattleAgainstBald.com to learn more about how the treatments work and their effectiveness.
Hair transplantation is very effective at treating male pattern baldness. Since hair follicles from the side and back of the head are resistant to the DHT androgens, hair simply must be transplanted from healthy parts of the scalp to the affected areas. The surgery has become increasingly popular in the last few years. Since 2004, there has been a 34% increase in hair transplant procedures, according to a survey conducted by the International Society of Hair Restoration Surgery (ISHRS). The increase is a result of an increase in effectiveness of the procedure and the natural results it yields. In 2006, 87% of hair restoration surgeries were for patients with pattern baldness.
Bosley Medical has performed nearly 200,000 of such procedures, making it one of the most reputable resources for victims of male pattern baldness to seek treatment. More information about Bosley Medical or hair restoration procedures is available at BattleAgainstBald.com, a blog that is sponsored by Bosley and documents the progress of two Bosley hair transplant patients, Seth and Torrance. It speaks to those who are struggling with any kind of hair loss and would like to learn more about hair restoration.
