Caucasians have the highest hair density among the ethnicities studied. Black people have the lowest. Asian people have hair density that falls somewhere in between.
Hair density.
According to HealthGuidance, Caucasians have the highest hair density, averaging approximately two hundreds strands of hair per square centimeter.
A gene variation of EDAR that arose about 30,000 years ago seems to give some people thicker strands of hair. More than 90% of Han Chinese, 70% of Japanese and Thai people, and 60% to 90% of Native Americans carry the “thick hair" version of the gene.
Most people of East Asian descent have thick, straight hair. This corresponds with a SNP (rs3827760) in the EDAR gene which is involved in hair follicle development. The ancestral allele of this SNP is the A-allele.
Geneticists at the University of Tokyo and several other institutions in Japan, Thailand, and Indonesia have now used the HapMap to explore why Japanese and Chinese people have thick hair: The cross-sectional area of East Asian hair fibers averages about 30% larger than that of Africans and 50% larger than that of ...
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 2005 study in the journal International Journal of Dermatology also found a difference among races in the rate of hair growth. For example, Asian hair grows the fastest, while African hair grows the slowest.
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.
Hair Curvature
In contrast to African hair that is more flattened and often has twists and turns, Asian hair tends to be round in shape, straight, and more cylindrical. The low values of average curvature in Asian hair suggest a relatively straight hair.
The African hair is generally curly or frizzy, and grows almost parallel to the scalp. It has the slowest growth rate of 0.9 centimeters per month due to its spiral structure which causes it to twist on itself as it grows. African hair has a flattened shape.
Type 1B hair is thicker – it is still very straight, but has medium texture so it has more volume. Hair that is type 1C is very thick and coarse, but still straight and shiny so it can be hard to make curls last. Type 2 hair is naturally wavy, with more curl than some types of hair but less than others.
Japan, Spain and Sweden are widely known for having people with healthy hair, but there are also other countries like India, France and Russia that are also known for helping people keep their hair natural and not messing with any artificial coloring.
The thickest strand of human hair is 772 micrometres (0.03 inches) and was plucked from the beard of Muhammad Umair Khan (Pakistan), in Lahore, Punjab, Pakistan, as verified on 3 March 2021. The hair was discovered on Muhammad's chin as part of his beard.
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.
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.
While the numbers are different according to different surveys, it appears that either Greece, Macedonia, or the Czech Republic has the highest rate of baldness in the world. These nations each have over 40% of men with acute hair loss.
Hair type 1A is super-straight. It doesn't even hold a curl! 1A is the rarest hair type. It is usually found on people of Asian descent.
Caucasian, Asian and Indian hair samples were put to the test for the World's Best Hair study. Their results put an end to any splitting of hairs over the issue: in terms of health, the Indian hair is the best, topping other ethnic groups on all four counts.
Because hair can be grouped into three different racial groups it can be used to identify if it came from someone of European, Asian, or African ancestry. As such, hair can be used to exclude people of certain racial group as suspects or as having been at a crime scene.
While type 4 hair is most commonly seen in Black individuals, this curl pattern is not limited to one race. People of any race or ethnicity, including Caucasians, can have type 4 hair, although it's not common.
Caucasians have the fullest hair among the three ethnic groups. Also, Caucasians lead with the highest density of facial hair among the three ethnicities. The men from these regions grow thicker beards, followed by blacks.
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.
Curly hair is not certain to a race or ethnicity, it appears all over the world in many forms. White, brown, black and everything inbetween! There is also a scale on which curly hair is classified (2a-4c).
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.
Ethnicity
Your race can have an effect on your facial hair growth. 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.
