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.
So where do curls, kinks, and waves come from then? Most evolutionary theorists agree that human ancestry can be traced back to Sub-Saharan Africa about 500,000 years ago, but it also appears in other hot, sunny places.
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).
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.
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, 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.
Caucasian hair can be smooth, wavy or curly.
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.
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.
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.
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.
There are plenty of blue-eyed Asians. This probably happens when the traditional blue-eyed allele comes into a family from a (possibly very distant) European ancestor. Blue eyes then resurface in a child generations later if they inherit the allele from both parents.
While some Japanese do have naturally curly hair, looking different is hard. Japanese straight perms were invented for the domestic market where schools often impose strict rules on students' personal appearances, after all.
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.
Yes, only 11% of the population have curly hair.
There are two reasons why we believe African hair texture is genetic. Firstly, the texture is universal in Africans, while nearly absent from other ethnic groups. Secondly, it is consistently passed down to the children in each new generation.
So where do curls, kinks, and waves come from then? Most evolutionary theorists agree that human ancestry can be traced back to Sub-Saharan Africa about 500,000 years ago, but it also appears in other hot, sunny places.
Evolutionary trait
It is known that 45% of European people have straight hair, 40% have wavy hair and 15% have curly hair.
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.
In fact, more people prefer curly hair to straight hair. Though beauty is seen differently by everyone, one thing is for sure; curly hair is getting a lot of love lately. In fact, in a survey conducted by StyleCaster, a surprising 58% of guys thought curly hair was sexier than other hair textures.
African Americans have the lowest hair density, averaging around 130 hairs per square centimeter and about 60,000 hair follicles on an adult scalp.
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. So, are we only genetically endowed, or do we even do a better job of grooming? S.
Racial gaps in life expectancy have long been recognized. The same CDC data show that nationally, Hispanic Americans have the longest life expectancy, followed by white and then Black Americans.
They suggest that either environmental or sexual selective pressure began acting on hair after humans began dispersing out of Africa, helping shape the wide range of human hair types present today. The limited evidence points to temperature as a factor. Curly hair may help keep the head cool in warm climates.
Curly hair is often associated with a fun-loving, warm hearted and outgoing personality. If you have curly hair you are perceived as being courageous, outspoken, and spontaneous. You are probably someone who likes to challenge perceptions and norms.
