The African hair is generally curly or frizzy, and grows almost parallel to the scalp. 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.
In general, frizzy hair is caused by a lack of moisture. To combat frizz, it's important to use styling and treatment methods that are friendly to curly hair. Read on to learn to decrease frizz while also accentuating your natural curls.
Type 2C hair waves start from the scalp and are thicker than other Type 2 subcategories. This coarse hair type is the most prone to frizz and forms an “S” shape when dry.
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.
Afro-textured hair, or kinky hair, is a human hair texture originating from sub-Saharan Africa. Each strand of this hair type grows in a tiny, angle-like helix shape. The overall effect is such that, contrasted with straight, wavy, or curly hair, afro-textured hair appears denser.
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.
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.
Because hair can be grouped into three different racial groups it can be used to identify if it came from someone of European, Asian, or African ancestry. As such, hair can be used to exclude people of certain racial group as suspects or as having been at a crime scene.
Hair Curvature
In contrast to African hair that is more flattened and often has twists and turns, Asian hair tends to be round in shape, straight, and more cylindrical. The low values of average curvature in Asian hair suggest a relatively straight hair.
While no two heads of hair are the same, there are three main classifications of hair type based on race Asian hair, Afro hair and Caucasian hair (which can also be referred to as European hair).
Genetics
The genetic makeup of your hair can cause frizzy hair. Curly hair and wavy hair tend to get a lot more frizzier when compared to straight hair. Your hair type is determined by the shape of your hair follicle. If you have a rounded follicle, your hair grows straight.
Frizz occurs on afro hair and curly hair more than any other types. Afro hair produces plenty of protective oils called sebum, but the oil struggles to spread evenly along the hair fibre due to the curly nature of afro hair.
Hair type 1A is super-straight. It doesn't even hold a curl! 1A is the rarest hair type. It is usually found on people of Asian descent.
The story of human migration and evolution is written in hair DNA. In sub-Saharan Africa, genes favour tight, curly hair. But in east Asia, mutations have led to straighter, thicker hair. In Europe, other mutations brought wavy and straw-coloured hair.
Even for healthy hair, high humidity environments can lead to frizz when your hair absorbs excess moisture where an anti-frizz moisture hair barrier spray can help. Over-styling damaging the hair cuticle and causing frizz. Heat damage and styling is another common culprit of frizzy hair.
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).
Caucasian hair can be smooth, wavy or curly. Its colorimetry can vary from blond to dark brown. 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.
The cuticle is the outer layer that protects the individual hair. The many layers on an Asian hair are also more dense and wider and thicker than on Caucasian hair. That gives the hair an illusion of being really shiny and silky.
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.
Not only is African hair often coiled, it also has a unique texture. So why is this? African hair produces plenty of protective oils, called sebum, which keeps our hair healthy. In fact, African hair actually produces more oils than Caucasian and Asian hair.
Both of your parents give you two pieces of genetic information, called alleles, that determine what your hair type will be. The two alleles from your biological father combine with two alleles from your biological mother, giving you four in all.
Different Curl Patterns
The presence of an amino acid called cysteine also contributes to coil and curl of your hair. Afro textured hair types typically have a high concentration of cysteine which form strong bonds with each other, creating tension which causes hair to bend and curl.
Caucasians Lose The Most Hair
In terms of which ethnicity tends to experience the most hair loss, Caucasians are the undisputed leaders.
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.
Ethnicity
People from Mediterranean countries tend to be able to grow thick beards compared to people from other regions. According to a 2016 study , Chinese men generally have less facial hair growth than Caucasian men.
