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.
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.
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.
Yes, East Asians can have naturally 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.
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.
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.
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.
Yes, only 11% of the population have curly hair.
It has been reported that Asian hair is generally straight and is the thickest, while its cross-section is the most round-shaped among these three. Caucasian hair is generally straight or wavy and is the thinnest, while its cross-section is relatively elliptic.
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 .
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.
Japan, as a country, isn't really geared toward those with 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.
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.
In fact, many Korean people have curly or wavy hair textures — but this is often a well-kept secret as most Koreans opt for the widely popular Korean Magic.
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%).
Coily Curls
The last, but most rare type of curl is the coily curl. This curl type is similar to that of an afro and when observed carefully, looks like the angular letter 'Z'.
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.
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.
