Hair type and texture are determined by several factors, including genetics. The African hair is more coiled and drier; Asian hair (Korean, Japanese) 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.
It is associated with the newly emerged alleles in both the TCHH gene and EDAR gene. The distributions of these straight hair related alleles (see figure) support the hypothesis that our human ancestors had curly hair; the straight hair found in East Asians and Caucasians likely developed independently.
People from countries like Japan, China and Korea tend to have mostly straight hair, while Africans have curly hair and Europeans are mostly a mixed bag.
Type 1: Straight Hair
Type 1A hair is very straight and fine, with no hint of wave or curl. As it is so straight and fine, when the natural oils travel to the ends, it tends to cause it to look like oily hair. It is the rarest hair type and is common among women of Asian descent.
Nearly 80% of Asians either have naturally straight hair or have styled it that way or they born with it. Straight hair is what is referred to as “Type 1” hair.
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.
We believe one of the reasons is that super-straight hair — also known as type 1a hair — is so rare. In fact, it's the rarest hair type. Only 2% of the world's population has 1a hair. It's mostly found in people of Asian descent.
And while the results did vary, in the end we found that 58% of the fellas agreed that curlier is sexier.

In fact, many Korean people have curly or wavy hair textures — but this is often a well-kept secret as most Koreans opt for the widely popular Korean Magic Straight Perm as opposed to wearing their natural curls.
Apart from genetic data and phenotypes, the researchers studied the ancestry percentages of the people due to the complex history of miscegenation of the inhabitants of the continent. “Europeans have straight hair due to the mutation of one genetic variation and it is a different one in the case of the Asians.
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 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.
Genetic factors appear to play a major role in determining hair texture—straight, wavy, or curly—and the thickness of individual strands of hair. Studies suggest that different genes influence hair texture and thickness in people of different ethnic backgrounds.
Type 1A hair is very straight and fine, with no waves or curls whatsoever. This hair type tends to get very oily and requires frequent shampooing. It is the rarest hair type and is common among women of Asian descent.

However, because it's the norm to see straight and sleek hair, curly haired boys and girls tend to think that their hair is some kind of unruly straight hair that isn't behaving.
The rarest skin color in the world is believed to be the white from albinism, a genetic mutation that causes a lack of melanin production in the human body.
