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 ...
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.
While Asian hair tends to be more coarse than other types, those of Asian descent can still experience thinning hair. Androgenetic alopecia and female pattern hair loss are common types of hair loss among Asian populations.
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.
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.
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.
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.
This may be related to differences in body composition, which is known to differ between ethnic groups. 62, 105 More specifically, black adults were found to have a relatively higher muscle mass (leading to a lower sarcopenia prevalence) compared to whites and Asians.
In view of the fact that many Japanese bathe and wash their hair daily, it's essential that they take well care of it. Modern-day shampoos mostly have ingredients that strip the hair of its natural oils, for example, sulfates.
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.
Japanese are famous for the beauty of their hair, which typically retains its health and sheen well into old age. They have used seaweed to cleanse, beautify, and nourish hair for a very long time.
* 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.
A survey released by Diamond, a Japanese online media outlet, on Sept. 22 has revealed the countries where male baldness is most common. Of all the Asian countries on the list, Japan came out on top, with an estimated 26.78% of Japanese men bald or balding, at least according to Japan's data.
Research suggests that whereas people in many parts of Europe and America now make do with just a shower nearly 90% of the time, in Japan between 70% and 80% of people still bathe in the traditional way at least several times a week. This rises to 90% or more in families with small children.
Caucasians Lose The Most Hair
In terms of which ethnicity tends to experience the most hair loss, Caucasians are the undisputed leaders.
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.
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.
Follicles that are more oval in shape cause curlier hair to grow. Very tightly coiled hair is due to the nearly flat, ribbon-like structure of their follicles. This hair texture is very common in people of African ancestry. Not only is African hair often coiled, it also has a unique texture.
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).
Africans have the widest and most prominent nose compared to other ethnic groups. Their noses are featured with enlarged nostrils, wide and rounded tips and a lack of protruded nasal bridge. West Africans have the widest noses (widest nostrils), while north Africans tend to have the smallest wide noses.
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.
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.
Curly hair isn't common in Japan like it is in other parts of the world, which is why it can be so difficult to find curly hair care products over here. And, to make things even tougher, the seasons in Japan aren't exactly kind to those of us with curly hair.
