African American hair is typically coarser and has a thicker texture than Caucasian hair. It also tends to have a higher density, giving it a fuller appearance. In contrast, Caucasian hair is typically finer, straighter, and has a lower density.
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.
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.
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.
Specifically, the average density of afro-textured hair was found to be approximately 190 hairs per square centimeter. This was significantly lower than that of European hair, which, on average, has approximately 227 hairs per square centimeter.
African American hair is typically coarser and has a thicker texture than Caucasian hair. It also tends to have a higher density, giving it a fuller appearance. In contrast, Caucasian hair is typically finer, straighter, and has a lower density.
Compared to silkier hair African-American hair contains more lipids, or fats, but the lipids are less bonded which is why the hair loves oils so much. Along with that, the follicle size is much thicker and it has a flattened elliptical cross section causing it to be curlier than other hair types.
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.
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.
There are two reasons why we believe African hair texture is genetic. Firstly, the texture is universal in Africans, while nearly absent from other ethnic groups. Secondly, it is consistently passed down to the children in each new generation.
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.
Keep in mind - the African American hair growth rate isn't too far off from other types. Over the course of a year, you won't notice too much difference. The reason you may feel that your hair growth is so much slower, though, is because of the tightly coiled style of your natural hair.
Individuals of African ancestry, for example, are more likely to have curly hair due to the oval shape of their hair follicles. Additionally, the Keratin Associated Protein (KAP) cluster genes, responsible for the structure of keratin fibers, have been found to have variations in many African populations.
Sweden. Livings standards, healthy lifestyles, geography, and diet are the primary factors why people in Sweden have the healthiest and beautiful hair.
Still, there are genetically influenced variations in people: Whites tend to be hairier than blacks, and among whites, Mediterranean and Semitic people tend to be hairier than Scandinavians and Anglo-Saxons. The least hairy peoples are Asians and American Indians.
Japan, Korea and the Rest of East Asia
East Asians are furthest from the Mediterranean region and also have the lowest rate of baldness which does not seem to be an accident. Incidentally, their baldness rate can range from 20% to the low 30s, which is still a significant portion of the population.
Hair Growth Rate
African hair has the lowest growth rate. Hair growth rate and hair diameter were reported to be associated with cuticle interscale distance.
Which country has the least bald men? According to the same Quora study, China is the country with the least number of bald men. Other countries like Japan, Thailand, South Korea, Taiwan, and Malaysia also have a lower prevalence of baldness.
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.
The physical activity and competition that go into being a professional athlete require the body to be producing testosterone around the clock. But as much as testosterone can benefit athletes on the field or court, it can hurt their appearance by destroying their hair follicles.
Men inherit the baldness gene from the X chromosome that they get from their mother. Female baldness is genetically inherited from either the mother's or father's side of the family. Baldness may be influenced by a number of other factors as well, including age, health, diet, hormones, seasonal changes and climate.
Native Americans, East Asian, Southeast Asian, Southwest Asian, Middle Eastern, Far East Russian, South Asian and Himalayan black-haired people have thicker hair due to the derived EDAR gene allele that is linked to thicker and potentially straighter hair in some parts of Asia, and shovel-shaped incisors.
According to the survey, the majority of men (42%) found blonde hair to be the most attractive. This was followed by brunette (36%), red (16%), black (5%), and gray (1%).
Long black hair was rated as more attractive than medium-length black hair in the study. While black hair is attractive on a woman, lighter and longer hair makes women look more attractive in some circumstances, research finds.
