From genotyping results, European hair shape varies mostly between wavy (46.6%) and straight (40.7%), with some curly hair (12.7%) (n = 2138) [10].
While most Eastern Europeans have straight hair, curly hair is common in the western Mediterranean shorelands of Europe, according to Carleton. According to The Head of the QIMR Genetic Epidemiology Laboratory, Professor Nick Martin, and Dr. Sarah Medland, approximately 17% of Italians have curly hair.
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.
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).
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.
The people of South Europe and North Africa have more curly and wavy hair than North Europe. Scotland and Ireland are a notable exception.
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.
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.
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.
It's a mutation in the gene that causes curly hair. I am 100% Scottish and I have very curly hair. My sister has even rarer pin straight hair. Roughly 45% of Europeans have curly hair gene even if they don't present curly hair.
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.
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.
This means two things: 1) if a person carries one allele for curly hair and another for straight hair, this person will have curly hair; 2) curly hair is a simple trait and is most likely determined by one single gene.
“Europeans have straight hair due to the mutation of one genetic variation and it is a different one in the case of the Asians. When they reached America, they hybridized with the native people and the result is like shuffling a deck.
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.
European hair has a fine denier and has natural light brown and blonde shades, meaning less processing. Not recommended for coarse hair textures, but can be used by hair types other than Caucasian. European hair is naturally silky and shiny and considered to be the highest quality of hair extensions you can buy.
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.
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.
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.
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 is considered a “dominant” gene trait. Straight hair is considered “recessive.” To put that in simple terms, that means that if one parent gives you a curly-haired gene and the other parent gives you a straight-haired gene, you'll be born with curly hair.
Type 4C. 4C is the kinkiest, coiliest hair type there is. Sometimes the zigzag curl pattern is so dense and fine that it may be hard to see individual strands without stretching each strand out. However, 4C hair is also super versatile and can be worn in so many different natural hairstyles.
