Hair Growth Rate Asian hair shows the fastest growth rate in comparison to the other two hair types. African hair has the lowest growth rate.
Asian hair the most dominant hair type in the world out speeds the rest with a growth rate of 1.3cm per month, and despite an estimated 80,000 to 140,000 scalp hairs, it usually has the least density.
A Caucasian person's hair also generally grows at a slightly faster rate than an African-American's hair. With that in mind, the common causes of hair loss are universal among the races, and most available treatments can be beneficial for hair restoration in both Caucasian and African-American patients.
African hair
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. The density of African hair is slightly higher than Asian hair.
Regardless of race, the larger the diameter of the hair fiber, the faster the rate of hair growth. Although there are no differences in the hair-growth cycle among Asian, African, and Caucasian hair subgroups, African hair has been found to grow at a slower rate, likely due to its smaller-diameter fibers.
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.
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.
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.
According to anthropologist and professor Ashley Montagu in 1989, Asian people and black people such as the San people are less hairy than white people. Montagu said that the hairless feature is a neotenous trait.
Human hair comes with all sorts of colors, textures and shapes. Notably, African hair is more coiled and dry; Asian hair is straighter and thicker; and Caucasian hair is somewhere in between with around 45% having straight hair, 40% having wavy hair, and 15% having curly hair.
Caucasian hair grows diagonally at an average of 1.2 centimeters per month.
Less than 20% of people have naturally curly hair.
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.
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.
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.
As it turns out, facial hair is not a functional physical human trait in the way we thought it was for many years. It's an ornamental one. In fact, of all the physical features on the human body—including other kinds of hair—facial hair is the only one that is purely or primarily ornamental.
1. Not a lot of Asian guys have facial hair and/or beards. A fairly obvious statement, but based on the findings of the survey: Only 28% have a mustache, goatee, beard, or some other form of facial hair. Only 8% have a beard.
On the other end of the spectrum are American Indians and Asians, who have the least hair on their bodies out of all ethnicities. All of the other races fall somewhere in between. These claims are echoed by the American Journal of Physical Anthropology.
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.
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.
Black women in particular are prone to a type of hair loss called traction alopecia, which is caused by heat, chemicals and tight styles that pull at the hair root, including some braids, dreadlocks, extensions and weaves.
* 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.
Race also plays a role in how early your hair turns gray. For instance, gray hair tends to occur earlier in Caucasians but later in Asians. African Americans may go gray later, too, with the average gray strand appearing around 43 years old.
It is not always true that Asians have thicker hair. Although it may appear thicker due to its dark hue, it is not necessarily thicker. Asians often have quite fine, thin and dry hair. This occurs when individuals shampoo their hair too frequently or when they do not take appropriate care of the hair itself.
