“The ethnicity with the least amount of
H. Harris, publishing in the British Journal of Dermatology in 1947, wrote Native Americans have the least body hair, Han Chinese people and black people have little body hair, white people have more body hair than black people and Ainu have the most body hair.
Asian hair grows the fastest, approximately 1.4 cm per month, Caucasian hair grows 1.2 cm, and African hair grows 0.9 cm due to its spiral structure.
People in the Mediterranean and Middle East often have more body hair due to genetic factors and evolutionary adaptations. Over time, their ancestors developed these traits, which may have helped with protection against the sun and regulating body temperature.
Hormonal Changes: An increase in androgens (male hormones) can lead to more body hair. This can happen due to conditions like polycystic ovary syndrome (PCOS), adrenal gland disorders, or hormonal imbalances. Genetics: Some individuals naturally have more body hair due to genetic factors.
Hirsutism is excess hair growth on the body or face. It's caused by excess hormones called androgens. For women, the hair may grow in places where men often have a lot of hair but women often don't.
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.
Asian hair
Because of its extra diameter, it is also the strongest, and most resistant to damage.
Results Total hair density (number of follicles per 4-mm punch biopsy specimen) and total number of terminal follicles and terminal anagen hairs were significantly lower in African Americans (P<. 001) than in whites and in a previously reported, predominantly white, population.
The hirsutism score was the highest in the Asian population (mean = 9.1, P = . 002) and Hispanic or Latino population (mean = 7.8, P = . 02), followed by others (mean = 7.4, P = . 04) and the Black or African American population (mean = 7.1, P = .
Chinese men were less likely than White men to experience balding in any pattern. Black participants also had lower odds for temporal, vertex, and severe balding but to a lesser extent than Chinese men.
Skin barrier function is reportedly stronger in darker skin tones (the stratum corneum is the skin barrier). Asian skin is reported to have similarities with Caucasian skin in terms of water loss and has the weakest barrier function.
It has been reported that Asian hair is generally straight and is the thickest, while its cross-section is the most round-shaped among these three. Caucasian hair is generally straight or wavy and is the thinnest, while its cross-section is relatively elliptic.
Total and free testosterone concentrations were lower in non-Hispanic blacks than in non-Hispanic whites; Mexican-Americans had the highest concentrations (total testosterone versus non-Hispanic white P=0.077).
This extraordinary young man is Lalit Patidar. The 18-year-old from India has the hairiest face on a person (male), with 201.72 hairs per square centimetre.
Based on these findings, we hypothesize that the thickened cuticle layer in pubic hair may have evolved as a defence mechanism against chemical damage from urine, urea and ammonia. Keywords: FT-IR imaging; cortex; curly hair; cuticle; hair; pubic hair; scalp hair; urine effects.
Black hair follicles have an elliptical shape that grow in a spiral and results in the slowest growth rate, at only about a third of an inch per month. It is also more fragile and prone to breakage. Asian hair follicles are round, usually very straight, and strong.
While our sample size for males was less than ideal, our results revealed no evidence for a relationship between hair testosterone concentrations, 2D:4D ratios and risk taking.
There is no specific ethnicity that can't grow facial hair, but East Asian individuals, such as Japanese and Chinese, tend to have less facial hair and slower growth rates compared to other ethnicities.
The average diameter, or thickness, of Asian hair is from 80 to 120 µm, compared to 65 µm in Caucasian hair and 55 µm in Black hair. The average diameter of Hispanic/Latino hair tends to fall between that of Asian and Caucasian. Caucasians have the highest hair density among the ethnicities studied.
There is no scientific basis to claim that any particular ethnicity or race has "more dominant" genes than others. Genetic diversity exists within and across all human populations. All humans belong to the same species, Homo sapiens, and share the vast majority of their DNA sequence.
“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.”
For example, dark body hair and facial hair is common in women from many areas of the world including the Mediterranean, Middle East and the Indian subcontinent. Familial hirsutism (which means excess hair is inherited) is perfectly normal and is not associated with any underlying medical condition.
Ethnicity - Different ethnic groups can tend to have larger or smaller gaps. For instance, Asian men don't often have very thick facial hair and thus have quite noticeable gaps on their philtrums. Meanwhile, Middle Eastern or Arabic men tend to have very thick facial hair with less of a gap.
The main purpose of body hair is to help regulate our temperature in addition to keeping dirt out of our body (in areas such as our eyes and nostrils).
