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 grows the fastest, approximately 1.4 cm per month, Caucasian hair grows 1.2 cm, and African hair grows 0.9 cm due to its spiral structure.
Asian hair has the highest growth rate and is by far the most resilient hair type. African hair generally has a slower growth rate and less tensile strength and breaks more easily than other groups. Caucasian hair is somewhere in between the two.
It was previously thought that Caucasian hair grew faster than Asian hair and that women's grew faster than men's; but newer research shows that the sexes do not differ significantly in speed of hair growth and that the hair of Chinese people grows faster than that of French Caucasians and West and Central Africans.
Yes, Caucasians (Indo-European and Semite populations) are the hairiest ethnic group. The cause is still unknown. It has been posited that the various Caucasian populations originated in Northern regions at the end of the last ice age.
According to anthropologist and professor Ashley Montagu in 1989, many East Asian people and African populations such as the San people are less hairy than Europeans and West Asian peoples. Montagu said that the hairless feature is a neotenous trait.
Asian hair is by far the thickest of all hair types – 80 - 120 µm in diameter. Because of its extra diameter, it is also the strongest, and most resistant to damage.
Of all the hair types, coily hair is seemingly the slowest to grow. That's because it has the densest structure of all and is prone to shrinkage, which can make even the fastest-growing of locks look like they haven't budged.
Debunking Myths About Facial Hair and Ethnicity
🚫 Myth 1: Only certain ethnicities can grow facial hair. ✅ Truth: Beard growth varies among individuals, but all ethnicities have the potential for facial hair.
There is no scientific basis to claim that any particular ethnicity or race has "more dominant" genes than others. Genetic diversity exists within and across all human populations. All humans belong to the same species, Homo sapiens, and share the vast majority of their DNA sequence.
Research into the diversity of hair growth profiles showed that black hair grows slower than other ethnicities. This is partly because black hair is more prone to breakages meaning any growth achieved can, quite literally, be snapped off in an instant!
The Red Yao women are widely known for growing their hair nearly six feet long as a sign of longevity.
Chinese men were less likely than White men to experience balding in any pattern. Black participants also had lower odds for temporal, vertex, and severe balding but to a lesser extent than Chinese men.
Skin barrier function is reportedly stronger in darker skin tones (the stratum corneum is the skin barrier). Asian skin is reported to have similarities with Caucasian skin in terms of water loss and has the weakest barrier function.
Racial differences in hair growth rate appear to be determined by genetic factors, rather than environmental factors, according to a 2016 study published in the European Journal of Dermatology. It should be noted, however, that hair growth does not occur at a steady rate in anyone, regardless of their race.
The average diameter, or thickness, of Asian hair is from 80 to 120 µm, compared to 65 µm in Caucasian hair and 55 µm in Black hair. The average diameter of Hispanic/Latino hair tends to fall between that of Asian and Caucasian. Caucasians have the highest hair density among the ethnicities studied.
Ethnicity - Different ethnic groups can tend to have larger or smaller gaps. For instance, Asian men don't often have very thick facial hair and thus have quite noticeable gaps on their philtrums. Meanwhile, Middle Eastern or Arabic men tend to have very thick facial hair with less of a gap.
Among the various Hispanic nations of the New World, the Mexicans have a particularly large amount of native American blood. The native Americans are descended from Siberian tribal peoples, and like most East Asians, do not grow full beards.
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.
African hair is seen to be much thicker and more dense meaning that the hair follicles are larger. Density represents the amount of hairs that grow from the head, with denser hair resulting from more hairs growing closer together from the scalp. An individual with high-density hair creates a fuller appearance of curls.
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. A type of baldness related to the normal function of the male hormone testosterone is called male-pattern baldness.
Asian hair demonstrates the highest hardness and elastic modulus, followed by Caucasian and African hairs, respectively.
Studies have shown that the morphology of the hair follicle can be influenced by a person's race. Individuals of African ancestry, for example, are more likely to have curly hair due to the oval shape of their hair follicles.
Black hair is the most common in Asia and Africa. Though this characteristic can also be seen throughout Europe as well, it is considerably less common. It can be found in Celtic populations such as in Ireland, Scotland and Wales.
