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.
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.
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.
Any of the 12 hair types listed below are not limited to any particular race or ethnicity and can be found in any individual. While it may be rare to see a white person with coily or kinky type 4 curls, it is certainly not impossible.
While the degree of curliness among Europeans and Asians is generally lower than that in Africans, some Europeans and Asians have kinky or very curly hair. From genotyping results, European hair shape varies mostly between wavy (46.6%) and straight (40.7%), with some curly hair (12.7%) (n = 2138) [10].
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.
It is known that 45% of European people have straight hair, 40% have wavy hair and 15% have curly hair.

What Is Kinky Hair? Kinky hair is really another word to describe curly hair. It's usually connected to the most textured pattern. Kinky, although somewhat subjective to individual interpretation, is most often associated with curl patterns in the 4A to 4C range.
Coily hair, commonly referred to as Afro-textured or kinky hair, Type 4 is naturally very dehydrated and spongy in texture. It can be soft and fine or thick and wiry. Strands from very tight, small curls of zig-zags right from the scalp and are prone to major shrinkage.
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.
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.
A: About 70 percent of Hispanics have curly or wavy hair.
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.
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.
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.
While most Eastern Europeans have straight hair, curly hair is common in the western Mediterranean shorelands of Europe, according to Carleton. According to The Head of the QIMR Genetic Epidemiology Laboratory, Professor Nick Martin, and Dr. Sarah Medland, approximately 17% of Italians have curly 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).
Follicles that are more oval in shape cause curlier hair to grow. Very tightly coiled hair is due to the nearly flat, ribbon-like structure of their follicles. This hair texture is very common in people of African ancestry. Not only is African hair often coiled, it also has a unique texture.
The gene for curly hair in Caucasians
It has been long established that curly hair is a dominant trait in Caucasians and straight hair is recessive.
Genotyping results show that 94.9% of Black people have curly hair. Additionally, 12.7% of Europeans and 12% of Asian people have curls. Biracial hair is a complicated term, and it does not refer specifically to one hair type or shape.
With Caucasians, research shows that “45 percent of European people have straight hair, 40 per cent have wavy hair and 15 per cent have curly hair.” Curly hair is not exclusive to one race and it does not mean you have to be mixed raced to have curly hair. It's actually not rare for Caucasians to have curly hair.
Sarah Medland, approximately 17% of Italians have curly hair. Overall, 45% of European people have straight hair, 40% have wavy, and 15% have curly hair. Therefore, Italians are slightly above the European curly hair average. Italian genes have adapted to both the northern and southern climates of Italy.
It is a dominant genetic trait, and it is found in people of all backgrounds and ethnicities. Black hair contains a large amount of eumelanin pigmentation, a type of melanin. This hair type contains a much more dense quantity of eumelanin in comparison to other hair colors, such as brown, blonde and red.
