What race has curly hair? People of African descent typically have curly hair. Curly hair has a defined curl pattern that ranges from loose waves to tight coils. However, people of other races can also have curly hair, depending on their genetic makeup.
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.
Many people of European and Asian descent have curly hair, and curl patterns vary greatly among people of African descent. As the combining of ethnicities becomes more common in an increasingly global world, these historical ways of describing hair may become increasingly less accurate.
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.
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.
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.
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.
Where hair type is concerned, curly is a dominant trait. So if one parent passes on the curly-hair gene and the other a straight-hair gene, it's more likely that their child will have some sort of curl pattern to their hair.
For example, variation in the TCHH gene is often responsible for curly vs straight hair in people with European ancestry, while variation in the EDAR gene is often responsible for straight hair in people with Asian ancestry.
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.
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.
An estimated 65 percent of the U.S. population has curly, coily or wavy hair, with a growing percentage of textured-hair women embracing their natural hair .
Researchers suggest that the evolution of curly hair in early humans was a crucial adaptive trait in equatorial Africa, offering effective protection from the sun's heat and minimizing the need for sweating. This passive cooling mechanism likely allowed for brain growth by conserving water and reducing heat.
While most Eastern Europeans have straight hair, curly hair is common in the western Mediterranean shorelands of Europe, according to Carleton.
It's a mixture of two things – humid or hot weather, and how moisturised your hair is to start with. The main cause of frizz is a lack of moisture in your hair. This causes your hair to seek out and absorb moisture from the air, causing frizz - which also explains why humidity can make frizz even worse.
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.
When we casually observe via our eyes, we may feel that we have inherited most of our hair features from either our mom or dad. However, the reality is that we inherit equal volume of genetic information from both mom and dad.
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.
A general observation across experiments was that straight hair was perceived as younger, healthier, and more attractive than wavy hair and darker shades (medium copper and brown) were perceived more positively than blonde hair.
According to the survey, the majority of men (42%) found blonde hair to be the most attractive. This was followed by brunette (36%), red (16%), black (5%), and gray (1%).
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.
Your hair is naturally voluminous
Curls adds volume to your hair effortlessly, and you never have to worry about it being flat, limp and lifeless like those with straight hair. Even on days when you straighten your curls, there is always going to be that little amount of volume that will make others go green with envy.
The genes that you inherit from both your parents determine how curly your hair appears. Your hair's appearance is determined by many factors. If you have children, the way your hair appears at birth is a clue to what genetic information they will receive. The texture of your hair can change through your lifetime.
