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).
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.
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.
It is known that 45% of European people have straight hair, 40% have wavy hair and 15% have curly hair.
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.
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.
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.
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.
A: About 70 percent of Hispanics have curly or wavy hair.
The same study showed that Asian (East and West) hair shape is also mostly straight (46.7%) or wavy (41.3%), with some curly hair (12%) (n = 92). However, African hair shape is mostly curly (94.9%), with some wavy hair (5.1%) (n = 39).
Hair morphology is one of the more conspicuous features of human variation and is particularly diverse among people of European ancestry, for which around 45% of individuals have straight hair, 40% have wavy hair, and 15% have curly hair.
Yes, only 11% of the population have curly 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.
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.
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.
Do white people with wavy hair have African ancestors? No, curly hair is found in every European country and very common in Dutch, Irish, English, Welsh, Scottish, etc decent.
However, the use of Chino has survived in modern Mexican Spanish via the term pelo chino (Chino hair) when referring to curly hair.
The diameter of Mexican hair is also intermediate between that of Asian and Caucasian hair. In general, Mexican hair most commonly possesses a mild curl – with 73% of subjects possessing hair shape that equates to a Type II ranking.
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.
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.
No, people with no Sub-Saharan African background can have curly hair. Curly hair is found in all background and it alone is not a sign of African ancestry.
Are curly hair people rare? 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.
Hair density.
According to HealthGuidance, Caucasians have the highest hair density, averaging approximately two hundreds strands of hair per square centimeter.
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.
When it comes to the race that tends to lose the most hair, that goes to Caucasians. Additionally, West Asian (specifically Indian) people are likely to experience similar hair loss levels to Caucasians.
