Less than 20% of people have naturally curly hair.
Hair type 1A is super-straight. It doesn't even hold a curl! 1A is the rarest hair type. It is usually found on people of Asian descent.
Think back to your childhood hair or before you started regular styling routines. Believe it or not, an estimated 65% of women have naturally curly hair. Chances are good that you're one of them!
Over 60% of the world's population has curly hair, yet most research to date has clumped hair into three catchall types - African, Asian, and Caucasian.
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.
1. You'll stand out from the crowd. Less than 20% of people have naturally curly hair.
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.
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.
Type 1A hair is very straight and fine, with no waves or curls whatsoever. This hair type tends to get very oily and requires frequent shampooing. It is the rarest hair type and is common among women of Asian descent.
And while the results did vary, in the end we found that 58% of the fellas agreed that curlier is sexier.
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.
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.
Fragility. Natural curly hair tends to be more fragile than straight hair. Due to the uneven shape of the hair fiber, the hair shaft can have “high spots” where the cuticle is slightly lifted compared to the rest of the hair fiber.
The rarest skin color in the world is believed to be the white from albinism, a genetic mutation that causes a lack of melanin production in the human body. Albinism affects 1 in every 3,000 to 20,000 people. What is this? People with albinism usually have very pale or colorless skin, hair, and eyes.
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. However, natural redheads may not exist for much longer.
Type 1 hair is hair that lies flat, or straight. Straight locks tend to be on the shinier side because the hair's natural oils are able to travel from root to tip. This hair category includes divisions 1A, 1B, and 1C. Type 1A is “stick” straight hair that has no hint of curl or wave.
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.
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.
Caucasian hair is generally straight or wavy and is the thinnest, while its cross-section is relatively elliptic. As for African hair, it is very curly, its thickness is intermediate and the shape of cross-section is highly elliptic.
Thick, curly hair is more prone to breakage and dryness than other hair types. However, with the right routine and hair care products, you can keep your curls healthy and looking good. To care for curly hair, board-certified dermatologists recommend these tips. Only wash your hair when needed.
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.
What is the biggest disadvantage of curly hair? The biggest disadvantage is brushing and detangling curly hair. Dry brushing can cause frizziness while wet hair is at its weakest state. You need to brush curly hair when it's damp that too in a down-to-upward motion.
