Male pattern baldness is the most common type of hair loss in men.
The cause for hair loss in men vary. In most cases, the reason is genetics. In others, there may be an underlying cause, an external factor, medications, and severe emotional incidents but the majority of male hair loss cases are hereditary. Despite the research, there are still many mysteries about the causes of hair loss in men.
In male pattern baldness, the hairline recedes and the crown thins.
The hair follicles in individuals with Androgenic alopecia or male pattern baldness are genetically sensitive to Dihydrotestosterone. The thinning crowns and receding hairlines are often due to Dihydrotestosterone.
What is Dihydrotestosterone?
Dihydrotestosterone is an androgen hormone; it is a derivative of testosterone. It plays a huge role in male pattern baldness, and is also vital to the male genitalia (genitals).
It has no role in female development, and has different roles such as giving the male characteristics – biological characteristics such as the male voice, and hair on the chests.
Testosterone turns into Dihydrotestosterone with the help of the enzymes. Dihydrotestosterone or DHT causes the hair follicles to shrink. Because the hair follicles in the hairline and crown areas are more sensitive to DHT, they fall out after a while.
DHT is thought to play a role in the enlargement of the prostate and prostate cancer too.
While still in the womb, DHT has a role in the development of the male genitalia. Even though there is more DHT in the prostate than the scalp, the reason why the levels of DHT change in the scalp, and lead to male pattern baldness holds a mystery. Research on the matter is going on.
