Curly hair is determined by factors you inherit from your biological mother and your biological father. There's no single gene that determines the way that your hair looks. The way your hair looks when you're born is also a clue into the genetic information you'd pass to your own children if you have them.

What race did curly hair originate from?

The Origin of Curls? 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.

Is curly hair from Europe?

People of European descent have 45% straight hair, 40% wavy, and 15% naturally curly hair. Professor Martin and colleague Dr Sarah Medland have previously found there is up to a 90% chance of inheriting the curly hair trait.

Is curly hair 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. But of the more than seven billion people on the planet, only 2 percent can claim to have this one special trait.

How did humans get curly hair?

The trichohyalin gene has long been known to play some role in the development of the hair follicle. Now the researchers at the Queensland Institute of Medical Research (QIMR) have found that it is the main gene responsible for creating curls.

Is curly hair related to ethnicity?

There isn't necessarily one single gene that causes your hair to become curly. Your hair type is the result of how your parent's DNA combines, in addition to your ethnicity. Studies suggest that people with different ancestral histories have different genes that are responsible for their hair type.

What is the rarest curl type?

That is because the straight follicles make it easier for natural oils to travel up and down your strands. Hair type 1A is super-straight. It doesn't even hold a curl! 1A is the rarest hair type.

Does hair come from Mom or Dad?

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.

Is curly hair hereditary?

Since curly hair is a dominant gene, there is a good likelihood that one or two curly-haired parents will produce a curly-haired cutie. But genetics are tricky, and there's a chance that two parents with curls could carry the straight hair recessive gene, and pass that onto their offspring.

What ethnicity has straight hair?

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.

Which race has the thinnest hair?

What does having curly hair mean?

Source) As already mentioned, curly hair is an autosomal dominant trait, which means that one of the parents has straight hair, while the other has curly hair. So you get genes of both types, but the dominant curly hair gene trumps the straight hair gene and expresses itself in the offspring, that is, in yourself.

Which race has the best hair?

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.

Can Japanese have curly hair?

It seems like many people believe that Asian people including Japanese have straight hair only. It's not right – actually some people in Japan (I don't know about other Asians) have wavy/curly hair.

Why do some races have curly hair?

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 Italians have curly hair?

Sarah Medland, approximately 17% of Italians have curly hair. Overall, 45% of European people have straight hair, 40% have wavy, and 15% have curly hair. Therefore, Italians are slightly above the European curly hair average. Italian genes have adapted to both the northern and southern climates of Italy.

Why did curly hair evolve?

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.

Is curly hair stronger than straight hair?

Fibres in the latter group were thicker, stronger and stiffer, with a greater scalp density. This means that curlier hair was found to be thicker, stronger and more resilient under mechanical forces than the near-straight hair.
