Hirsutism (HUR-soot-iz-um) is a condition in women that results in excessive growth of dark or coarse hair in a male-like pattern — face, chest and back. With hirsutism, extra hair growth often arises from excess male hormones (androgens), primarily testosterone.
It's believed that when our hairs gets longer, our head gets Vitamin D, phosphorus and calcium naturally. They in due course, enter into our body via two of the tubes which're at the brain's top part. This alteration alters our memory more strong and efficient.
The individual occurrence and characteristics of chest hair depend on the genetic disposition, the hormonal status and the age of the person. The genes primarily determine the amount, patterns and thickness of chest hair. Some men are very hairy, while others have no chest hair at all.
Men all have roughly the same amount of testosterone. Certain genes make your hair follicles more or less sensitive to the amount of testosterone in your body. Basically, an enzyme converts testosterone into a substance that shrinks hair follicles.
TO some people, being hairy is unattractive, but it comes with its advantages. According to health experts, hair follicles contain stem cells which help heal our skin from wounds and bruises. Also, these follicles have a network of blood vessels, nerves and fat, speeding up the healing process.
What Percentage Of Guys Have Chest Hair? A study of over 1100 men ages 17 - 71 found that only 6% had no chest hair at all, while 56% displayed a moderate amount of chest hair. 38% of men displayed a light amount of chest hair.

As we age, our prolonged exposure to testosterone starts to play a visible role on other body hair as well. Just like it transforms the vellus hair on a young man's face into a thick beard, it also changes the nearly invisible hair that grows in places like our ears into thicker strands.
Hair growth and size is modulated by hormones, in particular androgens like testosterone, which kick in during puberty. As men generally have higher levels of testosterone than women they tend to have more terminal hair.
Long hair DOES NOT drain any nutrients from the body. This is just another hair myth that has gained unreasonable popularity over the last few centuries.
But long hair requires a lot of time to maintain, which could divert someone’s attention from concentrating on their academic work,†Kiiza explains. He says it is justified to maintain a uniform hairstyle for all students in school to promote common identity and a sense of belonging among students.
The Hairiest Ethnicities: What Ethnicity Has the Most Hair? According to Personal Health via the New York Times, Caucasians are the hairiest ethnic group, with Semitic and Mediterranean people being the hairiest out of all Caucasians.
Hormones can also play a big part in hairiness levels in men. Testosterone is a hormone that is present in both men and women, but it is present in far higher levels in men. In addition, some men have higher testosterone levels than others, so the levels can vary between different men.
But the evolutionary reasons why hairiness varies with ethnicity are unclear. Caucasian people are generally hairier than the Japanese, for example, even though testosterone levels are the same. The difference seems to be in how sensitive the hair follicles are to those testosterone levels.
Still, there are genetically influenced variations in people: Whites tend to be hairier than blacks, and among whites, Mediterranean and Semitic people tend to be hairier than Scandinavians and Anglo-Saxons. The least hairy peoples are Asians and American Indians.
A survey of 117 male members of the high intelligence society Mensa found they were more likely than average to have a hairy chest. The most intelligent also had hair on their backs.
Bald men are no more virile and they don't have higher testosterone levels, though they do tend to have hairier arms, legs and chests. Perhaps most surprisingly, bald men don't actually have any fewer hairs on their heads.
Like so many things, it comes down to a mixture of genetics and hormones. We know that at least some of the genes for hairiness are carried on the X chromosome – and the way these genes are expressed varies between different men and ethnic groups – but hairiness also correlates with high testosterone levels.
Larry Gomez was born with hypertrichosis. With 98% of his body covered in hair, he's known as “Wolf Boy.” “I have to live with this because I have it,” he says. The condition caused him to be bullied as a child. He hopes to use his experience to inspire others.
83% of Men Trim Their Body Hair—Here's What They're Trimming.
While we may have had this much hair in our earlier caveman days, modern humans sprout nowhere near this much body hair and, as such, it is not an effective tool for keeping us warm. Consequently, shaving it all off won't have a noticeable effect on our overall temperature.
Hormones called androgens, which are present in both sexes, stimulate body hair (known as vellus hair) to darken and coarsen. Men have higher levels of androgens than women, so their body hair tends to be more prolific.
Leg hair and arm hair developed to help prevent chafing so we could move around without causing friction.
