H. Harris, publishing in the British Journal of Dermatology in 1947, wrote American Indians have the least body hair, Chinese and black people have little body hair, white people have more body hair than black people and Ainu have the most body hair.
“The ethnicity with the least amount of terminal hair is Asian, whereas people of Hispanic and Middle Eastern descent typically have the most. Other ethnicities fall somewhere in between. So what's normal, hair-wise, for you might not be normal for someone of a different ethnic background.”
What is the reason that some people have a lot of hairs on their body while others don't? Testosterone, plus genetics. Different ethnic groups have little hair such as Asians, others have quite a bit, such as Middle Easterners . Mother and Father and their Parents have much to do with that.
While some regions of the human body are naturally hairless, others become so due to a variety of diseases. According to the American Academy of Dermatology, more than 80 million people in America have androgenetic alopecia, also called male- or female-pattern baldness.
Lower amount of body and facial hair in men can accompany sever disorders such as Klinefelter syndrome, hypogonadotropic hypogonadism and XX male syndrome. Others are Noonan syndrome and sometimes sparse body hair can be seen in men with azoospermia.
The most common problem hair loss points to is one of several different skin conditions, like keratosis pilaris (an inflammatory disease of the hair follicles), eczema or seborrhea (dermatitis that leads to patches of itchy, red skin), psoriasis (a condition where the body's immune system start attacking healthy skin) ...
In rare cases, hair is eventually lost from the entire scalp, called alopecia totalis. There is a progression to complete loss of body hair, a type of the disease called alopecia universalis.
In the “choose the most attractive picture” questions, the photo of a woman without body hair was rated significantly more attractive than the one with body hair, with 95.2% of the participants choosing the hairless women.
Testosterone promotes body hair growth in men. As a result, one common symptom of low testosterone is a loss of body hair. You may notice thinning of your armpit or pubic hair. Many men find the change is most noticeable in their beard because they don't have to shave as often.
“Some genetic changes might be responsible for loss of hair. Others could be collateral damage after hair stops growing.”
* East Asian's have anywhere between 80,000 and 140,000 scalp hairs but, typically, they have fewer hairs per square centimetre than Caucasians. (They also tend to have less body and facial hair.) However, because the individual hair shafts are thicker, it gives the impression of greater hair density.
It is because of a variant in the EDAR gene, that arose in East Asia about 30,000 years ago. 93% of Han Chinese have this gene variant.
Many professional bodybuilders and fitness devotees shave because hair-free skin shows muscle definition better. Even if you're not in the pro circuit, there's no shame in showing off your gains at the gym. After all, you work hard and it shows –– so show what you've earned while hitting those weights.
African hair has the lowest growth rate. Hair growth rate and hair diameter were reported to be associated with cuticle interscale distance.
Genetics (which controls ethnicity) is the number one cause of hair loss. Certain races have higher rates of hair loss compared to others. Caucasians have the highest rates out of all the ethnic groups. On the opposite end of the spectrum, Native American Indians, Inuits, and Chinese have the lowest rates.
Caucasians Lose The Most Hair
In terms of which ethnicity tends to experience the most hair loss, Caucasians are the undisputed leaders.
This change in pitch and vocal quality is called presbyphonia and a lot of it has to do with declining levels of testosterone.
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.
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.
A: One study confirmed that women do find a hairless or nearly-hairless body as more attractive, but considered both hair reduction and retention as socially acceptable. Additionally, they found that men are aware that women prefer hairless men and don't think their bodies are ideal in this respect.
The bacteria on your skin breaks down the sweat, which creates the unpleasant smell. The bottom line is this: shaving armpits and body hair leads to fewer bacteria and less smell.
Out of the 105 women, 78 said they dig it (73%), while 28 (27%) would prefer a hairless man. However, even though the overwhelming majority likes a little hair, moderation was a common theme.
Reasons for hair loss on arms
Similar, to hair loss on the scalp, you can experience hair loss on your arms for a number of different reasons. Skin conditions; skin conditions such as dermatitis, seborrhea, psoriasis, eczema and keratosis pilaris can cause hair loss on both the arm and legs.
Hair loss is common in people living with lupus. The autoimmune disease causes body-wide inflammation that attacks the joints and skin, including the scalp. This can result in hair loss (alopecia ). Lupus-related hair loss can occur slowly, causing hair to become noticeably thinner gradually.
“There is a variety of normal: Some will notice very little body hair that's very light in color or texture, whereas others may have more body hair and it may be darker and coarser.”
