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.
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.
Caucasian hair usually appears thicker since it is more difficult to see through the scalp than other ethnic hair types. However, Asian hair is the thickest and coarsest hair of any ethnic group.
According to a global study based on 4 characteristics that determine healthy hair – thickness, tensile strength, shine, and smoothness – Indian women have the best hair in the world.
Caucasian hair
It grows obliquely, and grows about 1.2 centimeters per month. Caucasian hair has an oval shape. The density of Caucasian hair is the highest of the three ethnic groups, so it is the most dense.
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.
Rest assured, you're not alone! 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.
(Another fun fact: While men experience their thickest hair in their 20s, many women experience their thickest head of hair in this decade.)
What Ethnic Groups Have the Least Hair Loss? Studies have found that Native Americans have the lowest rates of hair loss from androgenetic alopecia. In fact, it's almost unknown there, though intermarriage with Caucasians could introduce the genetic tendency toward it to a family.
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.
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 the fastest growing hair, at a rate of approximately 1.4 centimeters per month. A strand of Asian hair has a somewhat round, even shape, but also has the lowest density of the three ethnicities.
Asian hair follicles are round, usually very straight, and strong. While not as dense as its counterparts, the hair is less likely to experience hair loss or breakage. Asian hair is also the fastest growing, at over half an inch per month. Caucasian hair can be stick straight, wavy, or curly.
There are scientific differences between hair ethnicities and East Asian hair is stronger, more resilient to damage and less prone to hair loss than other hair types. East Asian hair facts: * East Asian hair has twice the diameter and a much thicker cuticle than Caucasian hair.
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.
The age at which hair begins to turn grey and the increase in grey hair with age appear to be clearly linked to ethnic and geographical origin. At a similar age, subjects of Asian or African descent, who have the darkest hair, have fewer grey hairs than those of Caucasian origin, who have lighter hair tones.
Which country has the most baldness? With almost half (42.79 percent) of men going bald, baldness is most common in the Czech Republic. Just shy of the Czech Republic, Spain stands in second place with 42.6 percent of men going bald.
China is a country where the number of people who go bald is very low. Many of the other countries in this region, such as Taiwan, Hong Kong, Vietnam, Laos, Sri Lanka, South Korea, and Japan, also have very low percentages of male pattern baldness.
Fun fact: We have hair follicles covering just about every inch of our bodies. The only guaranteed hairless spots are the lips, the palms of the hands, and the soles of the feet. Given that ubiquity, it's surprising that we don't have more rogue hairs popping up in inconvenient or embarrassing spots.
Hair will generally be at its best in the early 20s, says Burg, because “hair shafts are thick and cuticles are tight.” Women may see changes if they are stressed, extreme dieting or using contraception.
In your 60s+
Your hair at this age: Sebum (oil) secretion tends to diminish in our 60s and 70s+, and this can make the hair dry and brittle. Our haemoglobin levels also tend to decrease during at this time of life, and this can affect hair health.
Many hair follicles stop producing new hairs. Men may start showing signs of baldness by the time they are 30 years old. Many men are nearly bald by age 60.
There are racial differences, however, in the incidence of male pattern baldness. The highest rates are found among Caucasians, followed by Afro-Caribbeans. Chinese and Japanese men have the lowest rates. For some unknown reason, this form of hair loss is does not occur among Native Americans.
While you may have heard that blonds suffer more hair loss than brunettes, the reality is that your natural hair color doesn't have any effect on your likelihood of experiencing hair loss.
Some people who don't lose their hair have low levels of the enzyme that converts testosterone, and so more recently researchers have been seeking ways of blocking the enzyme in others. A treatment called finasteride works on this principle, but it is expensive and needs to be or hair loss begins again.
