The researchers found 68% of white men reported hair loss compared to 64% of South Asian men and 59% of black men. (The relatively small differences are partially explained by the fact the white men in the study were older).
Caucasians Lose The Most Hair
After Caucasians, people of Afro-Caribbean heritage tended to experience the next highest levels of hair loss, with Asian men having the lowest hair loss rates.
Sub-Saharan Africans, East Asians and native Americans have little or no body hair. Sub-Saharan Africans and East Asians are the least hairy people. Northern Europeans, Mediterraneans and middle eastern are the most hairy people.
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.
Asian hair and Caucasian hair handle stress and fatigue well. Asian hair has the highest hardness and elasticity. It is resistant to stretching and can withstand a traction force of 60 to 65 grams.
You're less likely to experience male pattern baldness if you're of Chinese or Japanese descent. Male pattern baldness doesn't typically affect Native American, First Nations and Alaska Native peoples. You're more likely to have male pattern baldness if you have a family history of it.
Asian hair is by far the thickest of all hair types – 80 - 120 µm in diameter. Because of its extra diameter, it is also the strongest, and most resistant to damage.
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.
No matter how thick of a head of hair you were born with, you will gradually lose its thickness as you age. Hair amount is at its peak at age 35, but at age 45, it will wane by 5 percent, and at age 50, 11 percent. The pattern of hair thinning is different for both sexes.
Caucasians have the highest hair density. This can help explain – to some extent – why Caucasians lose more hair as they tend to have thicker hair and, thus, more hair to lose.
The study identified the Czech Republic as having the highest prevalence of baldness, where over 40% of adult males are affected. This is mainly due to genetics, hormonal factors, and lifestyle. Diet can also play a role.
Asian hair demonstrates the highest hardness and elastic modulus, followed by Caucasian and African hairs, respectively.
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.
So, if you have the X-linked baldness gene, you're likely to go bald. If you have one or more of these other baldness genes too, you're even more likely to go bald! This is why if your dad is bald, you may go bald as well. Your dad probably passed some of those non-X-linked baldness genes onto you.
Glazer et al also demonstrated that Asians had the highest sperm concentrations and Blacks the lowest, similar to our data.
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.
Of the practicing regions, Middle Eastern and northern African nations show the greatest frequencies of consanguinity. Among these populations with high levels of inbreeding, researchers have found several disorders prevalent among inbred offspring.
Anthropologist Joseph Deniker said in 1901 that the very hirsute peoples are the Ainus, Uyghurs, Iranians, Australian aborigines (Arnhem Land being less hairy), Toda, Dravidians and Melanesians, while the most glabrous peoples are the Indigenous Americans, San, and East Asians, who include Chinese, Koreans, Mongols, ...
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.
Melanin is what gives your hair (and skin) its natural color. People of African descent, Thai, and Chinese people, go grey more slowly.
Hair Loss in Your 30s and Beyond
By the time you turn 30, you have a 25% chance of displaying some balding. By age 50, 50% of men have at least some noticeable hair loss. By age 60, about two-thirds are either bald or have a balding pattern.
For example, studies suggest that Caucasians, particularly Northern European men, are more likely to experience male pattern baldness as compared to other ethnic backgrounds.
The short answer is that genes inherited from both sides of your family affect your chances of going bald. While we often hear that a man's chance of going bald is inherited from the maternal side, that's only partially true. The estimates vary, but about 60-70% of balding risk can be explained by someone's genetics1.
