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.
Curly hair is most common amongst people with African, Mediterranean and Native American ancestry. There's a specific gene that helps shape the hair shaft and determine hair texture, and it's called trichohyalin.
Curly hair , is somewhat common among people of Arab and Southern European descenants. Coily hair is common among people of African descents. Wavy hair are more noticeable among people of Asian or more northern European descents.
Studies have shown that the morphology of the hair follicle can be influenced by a person's race. Individuals of African ancestry, for example, are more likely to have curly hair due to the oval shape of their hair follicles.
Are There Germans With Curly Hair? A small percentage of Germans have curly hair. This is due to a combination of genetic and environmental factors.
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.
Type 1A: The rarest hair type, this one is very straight and fine with a “wispy” appearance. It's very difficult to get it to hold a curl. Type 1B: Though still straight, this type has a medium (rather than fine) texture and a little more volume.
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.
Asian hair is the thickest, with a larger diameter of about 70 µm. Caucasian hair has an average diameter of 65 µm, and African hair is the finest, with a diameter of 55 µm. The cross-section of Asian hair is the most round and uniform, Caucasian hair has an elliptical shape, and African hair has a flattened shape.
Slavic hair is the hair of European descent. Because of their nutrient-rich diet, Slavic hair is the silkiest, thinnest and finest on the market. The colours it generally comes in are light blonde to medium brown.
While the name suggests a connection to Irish heritage, and it is indeed commonly seen in those of Irish descent, it's important to note that anyone can have this curl pattern. The main characteristic is the noticeable difference in texture between the top layer and the underneath layers of hair.
Why you have curly hair, and are probably reading about it here with us at NaturAll Club, is because of the DNA different areas across the world favor. In Africa, the people's genes tend to be curly or tight. Asia has mutations that give straight hair, while Europe has mutations that favor wavy or straight hair types.
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.
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. You celebrate your uniqueness and value your roots.
Kinky hair, is a human hair texture prevalent in the indigenous populations of many regions with hot climates, mainly Sub-Saharan Africa, Melanesia and Australia.
Curly hair is found across all ethnicities, though its prevalence and type can vary. It is common among people of African descent, who often have tightly coiled hair. Wavy and curly hair types are also prevalent in Middle Eastern, European, South Asian, and Latin American populations due to diverse genetic backgrounds.
The curls stop the natural flow of oil down to the tips of the strand, preventing your hair from getting the adequate lubrication it needs for protection. The moisture barrier breaks and is unable to retain any moisture, which causes your hair to turn frizzy.
“We suspect that the structure of human curls allows for a lot of air pockets between hair strands. In other words, you can have a lot of depth (from the scalp to the top of the hair) without having a lot of density, which would keep heat in as well as keep heat out,” says Dr Tina Lasisi, PhD, coauthor of the study.
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.
The rarest eye colors are red and violet, which are primarily found in individuals with albinism. Excluding those affected by albinism, green and gray eyes are considered the most uncommon.
Now you know what is the most common hair colour in the world, but what about the rarest? The rarest natural hair colour is red, which makes up only one to two percent of the global population. You commonly see these hair colours in western and northern areas of Europe, especially Scotland and Ireland.
Individuals with curly hair embrace the carpe diem ethos: seize the day and savour life to the fullest. Consequently, your personality exudes passion, dynamism, insight, warmth, and a bubbly disposition. These traits contribute to your ability to meet deadlines.
Hair genetics can come from either parent, and multiple genes can determine hair traits, such as color, texture, and growth. Genes can also affect hair loss. Although it can run in families, this is not always the case.
Curly-haired people need to sweat less to release heat and cool off, helping them retain water in hot temperatures. This might be why curls are way more common among people that live in notoriously hot countries such as Africa, the Middle East, South America, parts of South-East Asia and Mediterranean countries.
