Curly hair is considered a “
Can you activate the curly hair gene? People who have a curly-haired parent assume that they can activate this gene. If by puberty your hair doesn't turn curly then you can't activate a curly hair gene.
When you wake up in the morning (after sleeping on your fancy silk pillowcase), your curls might look a little flat. To perk them back up, spray your hair with water, leave-in conditioner, or a spray gel to add more moisture. Work it through your hair section by section to revive the shape of the curls.
Genes control curly hair
So far, the main driver to have been identified is a gene that produces a protein called trichohyalin (TCHH), which strengthens the growing hair.
"Brushing your hair in the shower and not touching it once you add products will help to keep the curl pattern intact," Sturdivant-Drew adds, and that using a silk pillowcase or hair scarf at night can help retain shine.
The key is not to fight your natural curls or waves. This hair type needs plenty of moisture and hydration, as well as heat protection, curl-enhancing products and a gentle approach to drying and combing. If you have naturally straight hair, fear not – you can still get curls!
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.
Your hair may become curly with age if you inherited both straight and curly hair genes from your parents. Some of these genes can be inactive at birth but then become turned on by hormones, aging, or other factors including medication, nutrition, stress, illness, or pollution.
And while the results did vary, in the end we found that 58% of the fellas agreed that curlier is sexier.
It could be that neither of your parents have curly hair, but an ancestor did. Then the curly hair gene could have been passed down through generations and your parents are carrier of that gene, which manifested its trait in you!
So, while curly-haired parents tend to have curly-haired kids, there's no guarantee it will happen. Because many different genes are involved, even a curly-haired parent can have—and pass along—straight-hair gene variations.
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.
It's very normal to have a mix of curl patterns on the same head of hair. It starts with your genetics. You see, the gene for curly hair is not completely dominant. It can remain dormant until activated and then it changes the shape of the hair follicle which changes the hair that grows from it.
Hormonal changes like pregnancy, puberty or menopause can cause your curl pattern to change drastically. The shape of your hair follicles defines your curl pattern and texture, so when your body goes through a major hormonal overhaul, it can also change the shape of your follicles, thus changing your curl pattern.
But this isn't the case because blonde hair is the 2nd rarest natural hair color. Only 3% of the total global population is blonde.
Caucasian hair is generally straight or wavy and is the thinnest, while its cross-section is relatively elliptic.
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.
Brushing curly hair too often is a bad idea. In order to maintain the integrity of your curls, try to keep contact between your brush and curls to a minimum if possible. A good recommendation is to brush hair with the same frequency with which you wash your strands, but what works best can vary based on hair type.
Sea salt spray can create beachy waves on straight or fine hair. It can enhance waves and curls in naturally wavy or curly hair. Sea salt spray adds texture to all hair types.
The people of South Europe and North Africa have more curly and wavy hair than North Europe. Scotland and Ireland are a notable exception.
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.
