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.
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.
Human hair comes with all sorts of colors, textures and shapes. Notably, African hair is more coiled and dry; Asian hair 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.
The terms 'European hair' and 'Caucasian hair' are often used interchangeably and are taken to denote 'wavy' to 'straight' hair; 'East Asian' hair is taken to mean 'pin-straight' hair; and 'African' or 'ethnic' hair is taken to signify 'curly' or 'very curly' hair.
Peoples originating from sub-Saharan Africa tend to have very strong curl to their hair. Peoples from Eurasia less so. The important word here is less, in every European population there are people who have naturally curly hair.
Less than 20% of people have naturally curly hair.
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.
Many Asians have naturally straight hair, but there is a significant group of us who do have naturally curly or wavy hair! 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 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.
Lots of traits are statistically rare: Left-handedness (just 10 percent of the population!), curly hair (11 percent!), and blond hair (4 percent!), to name a few. But of the more than seven billion people on the planet, only 2 percent can claim to have this one special trait.
Another common trait of South France people is darker, curlier hair. Again, this is a blend of the cultural influences that have made up France over the years.
One popular myth is that hair loss in men is passed down from the mother's side of the family while hair loss in women is passed down from the father's side; however, the truth is that the genes for hair loss and hair loss itself are actually passed down from both sides of the family.
Follicle Shape- The shape of your hair follicle largely determines your curl. Oval follicle shapes produce curly hair while round follicles produce straight hair.
No, curly hair is found in every European country and very common in Dutch, Irish, English, Welsh, Scottish, etc decent. These people don't have African admixtures. Curly hair is also not based on one specific gene. In Caucasians, it results from a different gene.
That shape depends on the shape of the hair follicle. This tiny structure guides the hair fiber up a sort of tube as it grows. The inside of the tube determines if the hair is curly or straight — ovals produce curly hair and circular tubes yield straight hair.
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.
H. Harris, publishing in the British Journal of Dermatology in 1947, wrote American Indians have the least body hair, Chinese and black people have little body hair, white people have more body hair than black people and Ainu have the most body hair.
Caucasian. Caucasian people have rounder hair follicles, resulting for the most part in straight or wavy hair.
The majority of the Japanese population has naturally straight hair and many who do have some form of curly hair have it chemically straightened in order to fit in. It isn't surprising then that there are very few hair salons that will even attempt to work with curly hair, let alone excel at it.
Yes, East Asians can have naturally curly hair.
Discussing about the texture of Vietnamese hair, the hair texture of Vietnamese hair is very special, it is straight, smooth, soft and silky. Because natural shapes of Vietnamese hair is straight, it is not easily tangling.
The rarest natural hair colour is red, which makes up only one to two percent of the global population. You commonly see these hair colours in western and northern areas of Europe, especially Scotland and Ireland. However, natural redheads may not exist for much longer.
The rarest hair and eye color combination is red hair with blue eyes, occurring in less than 1% of the global population.
