Hair loss causes. Common causes for hair loss

There are many causes of baldness, including serious illness, reaction to certain medication and stress, but by far the most common is Male Pattern Baldness (MPB) or Andogenic Alopecia. MPB is caused by a combination of two factors: a familial predisposition and Dihydrotestosterone (DHT).

DHT is a byproduct of testosterone, and is consequently present in every male. Scientists have shown that DHT shrinks hair follicles, and that if DHT is suppressed, the follicles will continue to thrive.

In 1949 a landmark study was performed that explained the causes of MPB. A grouping of castrated convicts, males who were thus not producing testosterone, were divided into two groups. The first group were those who had a category history of MPB, and the s group were those with no family history of balding. Both groups were injected with testosterone; the radical with a family history of MPB began losing their hair within weeks, while the radical with no family history lost no hair, but did get to get a mature hairline. When the injections were stopped, the progression of thinning stopped.

Looking past the inhumane and surprising extremes of this experiment, it was observed that MPB was an inherited trait that is triggered with the front of testosterone. Since that experiment, we have learned that it is not testosterone but the testosterone byproduct DHT that causes hair loss.

Hair follicles that are medium to DHT must be open to the hormone for a protracted flow of sentence for the affected follicle to discharge the miniaturization process. Today, with proper intervention, this procedure can be slowed or even stopped if caught early enough.

What MPB sufferers inherit are hair follicles from their mothers or fathers with a genetic predisposition to DHT. Hair follicles sensitive to DHT begin to miniaturize, shortening the lifespan of each hair follicle affected. Eventually, these follicles stop producing cosmetically acceptable hair.

MPB is characterized by a receding hairline and cutting in the temple, crown or vertex area. These areas are the most medium to DHT. For some men, DHT even thins the fuzz on the support of the head, although this region is commonly spared, leaving a permanent donor area that can be exploited for modern hair transplants.

There are yet many factors about the heritage of baldness that we don`t understand. I often see a male with a warm family history of MPB that says he has an elder brother with little or no balding. As well, some young adult males bald rapidly up until the age of 35, whereupon the balding pattern stops. In contrast, males can also have small or no thinning up until their early 40s, and so lose all or most of their hair in the following 20 years, balding almost entirely by age 60. Unfortunately, we cannot call the precise course each individual`s balding will take when he is in the early balding stages. But broadly speaking, the sooner you start losing hair, the more hair you are leaving to lose.
