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.
Curly hair can be found in all parts of the world. 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.
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.
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.
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.
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.
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.
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.
Less than 20% of people have naturally curly hair. The percentage gets even smaller when you consider the scores of guys out there who don't embrace their curls. If you're looking for something to help you stand out—and look dashing while doing it—then it's time to go natural.
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.
Most Egyptian women have naturally curly hair. It's a dominant feature.
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.
Curly hair is dominant, so someone is more likely to have curly or wavy hair if at least one of their parents does. Recent research points to trichohyalin, a protein in hair follicles, as having primary influence over hair curl. However, there are many genes contributing to hair curliness, most of them unknown.
Curly hair is found among many Europeans, North Africans and West Asians, South East Asians and not only among Jews. The gene for curly hair likely originated with early humans or their ancestor Homo erectus in Eurasia.
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.
Yes, East Asians can have naturally curly 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.
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.
And while the results did vary, in the end we found that 58% of the fellas agreed that curlier is sexier.
Even though curly hair is very common, not everyone has a curl pattern. Some people have 1A, or straight hair, meaning their hair doesn't naturally hold a curl.
Evolutionary trait
It is known that 45% of European people have straight hair, 40% have wavy hair and 15% have curly hair. They had previously established the heritability of curly hair, finding there was as much as a 90% chance of it being an inherited trait.
Thick, curly hair is more prone to breakage and dryness than other hair types. However, with the right routine and hair care products, you can keep your curls healthy and looking good. To care for curly hair, board-certified dermatologists recommend these tips. Only wash your hair when needed.
Over 60% of the world's population has curly hair, yet most research to date has clumped hair into three catchall types - African, Asian, and Caucasian.
