The cuticle layer in Asians is thicker with more compact cuticle cells than that in Caucasians. Asian hair generally exhibits the strongest mechanical properties, and its cross-sectional area is determined greatly by genetic variations, particularly from the ectodysplasin A receptor gene.
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.
It's thick.
The reason Asian hair tends to be thicker is that it has around 10 layers of cuticles. Cuticles are the small areas around the inner protein structure of your hair–they are there to protect those proteins.
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 ...
Asian hair, usually smooth and brown to black in color, grows perpendicular to the scalp. It has the fastest growth rate with about 1.4 centimeters per month. Asian hair has a rather round and uniform shape. Nevertheless, the density of Asian hair is the lowest of the 3 ethnic groups.
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. Meanwhile it's almost nonexistent in people of African and European descent. Both age and sex can also affect your hair shaft thickness.
Asian hair is also the straightest hair of any ethnic group. According to HealthGuidance, African American hair texture varies. Some people have thicker, coarser hair whereas others have finer hair. Many have a mixture of fine and coarse hair.
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.
There are plenty of blue-eyed Asians. This probably happens when the traditional blue-eyed allele comes into a family from a (possibly very distant) European ancestor. Blue eyes then resurface in a child generations later if they inherit the allele from both parents.
Asian and black skin has thicker and more compact dermis than white skin, with the thickness being proportional to the degree of pigmentation. This likely contributes to the lower incidence of facial rhytides in Asians and blacks.
* East Asian hair has twice the diameter and a much thicker cuticle than Caucasian hair. Most hair types have around five layers of cuticles while East Asian hair has closer to ten.
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.
Thicker strands of hair are more likely to have a defect, making them more prone to breakage, the researchers believe. Lustrous, thick hair may be desirable but it is not necessarily the strongest. Scientists said thin hair tends to be stronger than thicker locks, after looking at the way they break.
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. So, are we only genetically endowed, or do we even do a better job of grooming? S.
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. Let's dive in deeper.
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.
Green Eyes
Green is considered by some to be the actual rarest eye color in the world, though others would say it's been dethroned by red, violet, and grey eyes.
A couple of years ago, scientist determined that BLUE EYES was a MUTATION that occurred around 6,000 years ago and it stems from A BLACK MALE AFRICAN ORIGIN. They report several archeological proofs puts this event around the BLACK SEA AREA.
Blond hair has also developed in other populations, although it is usually not as common, and can be found among natives of the Solomon Islands, Vanuatu and Fiji, among the Berbers of North Africa, and among some Asians.
We most easily memorize whatever we can say or read within that two-second span. And Chinese speakers get that list of numbers — 4, 8, 5, 3, 9, 7, 6 — right almost every time because, unlike English, their language allows them to fit all those seven numbers into two seconds. Chinese number words are remarkably brief.
Asians have thicker skin because we have a thicker dermis due to larger and more numerous collagen-producing cells (known as fibroblasts) in this second layer of our skin. All those extra fibroblasts produce extra collagen which helps to preserve our skin's elasticity.
The Asian Flush is a reaction to alcohol among East Asians. Those who experience the condition get red in the face if they have an alcoholic drink. This is due to a deficiency within an enzyme called ALDH2, which breaks down alcohol in the liver.
The story of human migration and evolution is written in hair DNA. In sub-Saharan Africa, genes favour tight, curly hair. But in east Asia, mutations have led to straighter, thicker hair. In Europe, other mutations brought wavy and straw-coloured hair.
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. The G-allele is the newly derived allele that leads to the thick, straight 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).
