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.
The Caucasian ethnicity has the most hair, primarily the Mediterranean and Semitic groups. The Asians and Indians are on the other side of the spectrum, with the least hairs on their heads and bodies, while the remaining ethnicities fall in between.
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.
The body hair of Asians differs from that of other races in a number of ways. Asians have shorter, straighter, thinner, and less body hair than Caucasians and black individuals. Since a case reported by Itin et al. in 1994, research studies of knotted body hair have rarely been reported.
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.
Hirsutism is excess hair growth on the body or face. For women, the hair may grow in areas where men often have a lot of hair, but women often don't. This includes the upper lip, chin, chest, and back. It's caused by an excess of male hormones called androgens.
Familial hirsutism (which means excess hair is inherited) is perfectly normal and is not associated with any underlying medical condition.
Which people have less body hair? Oriental peoples have the least amount of noticeable hair; Southern European and Mediterranean groups, the most. Black people have more hair than Orientals but less than Northern Europeans and Scandinavians.
Relevant paragraph from Wikipedia from the article on body odor below, but the TL;DR is that there's a gene called ABCC11 that is non-functional in 80 to 95 percent of East Asians. That allele determines both apocrine sweat gland size and activity, concentration of protein in apocrine sweat, and, oddly, wet-type vs.
Leg, chest and back hair
A quarter (26%) find men's hairy legs attractive (21% of men and 30% of women said this). Among 16-24-year-old women, 57% – a rate significantly more than any other age/gender group – say hairy legs on women are neither attractive nor unattractive.
What race grows the best beard? People from Mediterranean countries tend to be able to grow thick beards compared to people from other regions. According to a 2016 study , Chinese men generally have less facial hair growth than Caucasian men.
Caucasians Lose The Most Hair
In terms of which ethnicity tends to experience the most hair loss, Caucasians are the undisputed leaders.
this actually goes back 35,000 years ago from a genetic mutation. the EDAR gene which is the gene that is responsible for developing the skin. was actually found to be mutated in Asians. this gene is responsible for making a protein that creates hair.
In general, however, the highest rates of male pattern baldness are found among Caucasian men. The second highest rates belong to Afro-Caribbeans. Native Americans, on the other hand, do not struggle much with male pattern baldness. As mentioned, pattern baldness is genetic, that is, hereditary.
Asian skin has a thicker dermis than white skin, meaning it contains more collagen. Research from 2019 noted that Asian females may not notice wrinkles until they reach their 50s. Loss of connective tissue will not occur at the same speed for all people in these racial groups.
Many Asians have naturally straight hair, but there is a significant group of us who do have naturally curly or wavy hair! However, because it's the norm to see straight and sleek hair, curly haired boys and girls tend to think that their hair is some kind of unruly straight hair that isn't behaving.
As it turns out, a percentage of the population lack the gene that prevents stinky pits. According to researchers from the University of Bristol, that special gene is called ABCC11.
Both of your parents give you two pieces of genetic information, called alleles, that determine what your hair type will be. The two alleles from your biological father combine with two alleles from your biological mother, giving you four in all.
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.
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.
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.
You have a hormone imbalance
This means you can get hair where you don't want it, like your face, belly, thighs, or butt. According to Mount Sinai Medical Center, about half of cases are caused by high levels of male sex hormones or “androgens,” like testosterone.
Many hair follicles stop producing new hairs. Men may start showing signs of baldness by the time they are 30 years old. Many men are nearly bald by age 60.
As a plastic surgeon sees it, there are structural reasons that people age differently. “Asians have a wider bone structure than a typical Caucasian face,” Dobryansky notes. “The soft-tissue loss is seen and felt to a lesser extent because of the wider structure.
The frequencies of the A and G alleles vary markedly across different ethnic groups. The A allele is very common in East Asians, and as expected, most people in this population don't need to use deodorant. And so they don't use it—it's estimated that only 7% of North East Asians regularly use deodorant.
