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.
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.
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. But of the more than seven billion people on the planet, only 2 percent can claim to have this one special trait.
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. If you're looking for something to help you stand out—and look dashing while doing it—then it's time to go natural.
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.
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.
And while the results did vary, in the end we found that 58% of the fellas agreed that curlier is sexier. Here's what they had to say: Bobby, 21: For me, Lea Michele does look good with both straight and curly hair but something about her in this curly picture makes her seem more welcoming. It's not just the smile.
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.
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.
Whether it is straight, curly, or wavy, your hair is unique to you. But what biology is at play? Curvy or straight hair follicles set the look of each hair throughout your life.
Naturally curly hair is an almost uniquely human trait. Now we might know why. Katie has a PhD in maths, specializing in the intersection of dynamical systems and number theory. Humans are a bit weird, all things considered.
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.
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.
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.
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.
Most women think brunette hair is the sexiest, as 25% of those polled favoured this option. Womens' second preference is blonde, which was voted as the sexiest hair colour by 19.6% of women. Again, red took third spot, accounting for 11.8% of womens' votes.
Women with curly, textured hair tend to look younger than straight-haired counterparts as they age. Because of the natural volume that comes with having curly hair, thinning is less noticeable. Consider your frizz and volume to be a blessing in disguise! Are you looking for a new young, fresh look for fall?
On average, hair grows half an inch per month, or about six inches per year - but with curls, it can feel like a much slower process. "Curly hair grows at the same rate as straight hair," says Dr. Michelle Henry, board certified dermatologist and Clinical Instructor of Dermatology at Weill Cornell Medical College.
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.
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.
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.
