How you really are more manly being bald?

Bruce Willis, Andre Agassi and Michael Jordan; are the three strong and masculine men, admired by many women. But they have something else in common: they are bald. It is often said that the bald are manlier. The popular theory is that they have higher levels of the hormone testosterone, which makes them more masculine and increases sexual power, but also makes your hair fall are more than the average member of their gender. The truth, however, is a bit more complex.

It's true that hair loss is dependent on testosterone. In 1960 a Yale University doctor named James B. Hamilton studied 21 boys who had been castrated. At that time, it was a practice that was applied at times when children were diagnosed with mental or behavioral problems.

 

Hamilton were followed, some of them up to 18 years, and found no signs that were developing male pattern baldness as they got older.

 

On the other hand, men of the same age who were still intact, and therefore producing testosterone, and had tickets.

 

Related but not responsible

 

Hamilton was not the first to discover the link between testosterone and baldness, both Hippocrates and Aristotle had observed the same centuries earlier.

 

The finding of Hamilton seemed to indicate that high levels of testosterone can result in baldness, but the fact is that the level is irrelevant, as long as there some amount of hormone present.

 

Castrated, with almost no testosterone, may retain their hair, but men with low testosterone levels can lose.

 

That is because it is the amount of the hormone circulating in the blood stream which dictates baldness: is genetics.

It is thought that multiple genes are involved, with the result that the hair follicles become particularly sensitive to tiny amounts of testosterone.

 

Has not yet fully understand the process, but involves an enzyme that converts testosterone to dihydrotestosterone, a substance called, which causes hair follicles shrink some people, possibly by interrupting the supply of blood and nutrients.

 

As the follicle shrinks, the growth cycle is shortened and the new hairs are becoming thinner and thinner until only hair on the scalp.

 

Eventually, the follicle becomes inactive and no longer produced hair.

 

Bald men are genetically inclined to be more sensitive to dihydrotestosterone.

 

A chin follicle does not affect any hormones, so the beard is still growing.

 

Hope

 

Some who do not lose their hair have low levels of the enzyme that changes testosterone so recently been looking for ways to block that enzyme in others.

 

A treatment called Finasteride works on the basis of this principle, but it is expensive and requires continuous or hair turns to fall.

 

Meanwhile, scientists are still trying to understand the mechanism that causes the hair to stop growing.

In 2012, a team of researchers examined sections scalp with and without hair and found that there were stem cells in the follicles still present in both areas, but in the bald part were not progressing to the next stage, which is normally calls develop in progenitor cells.

 

The study gives hope that can one day grow hair on bald parts of the head, if scientists find ways to block whatever it is preventing the growth or spreading. And at this time there are researchers investigating specific proteins that could provide such a trigger.

 

Baldness seems involved in myths that many other conditions, possibly because it seem so random distribution we seek explanations.

 

If you have lost your hair, sorry but you cannot be manlier. But you can blame your parents. They passed the genes, after all.
