If a hair follicle is thick and round, amino acids called cysteines, have a lower chance of coming together close enough to create tight bonds. This results in hair that's likely to be straight.
Others have curls and straighten them out. But for a few people, their hair actually changes shape and texture on its own — and not just because of the weather. Scientists don't know exactly why this happens, but it probably has to do with a combination of genetics, hormones and body chemistry.
Sometimes curly hair looks limp because the curls weigh down the roots, especially when there is a lot of density. This also tends to happen while the hair is drying on wash days. In other cases, roots lose their volume after sleeping, especially in those who wear a buff or a silk cap to protect their curls overnight.
Straight, sleek hair makes quite a statement, and with a little effort (and a lot of patience!), it's totally doable. Depending upon how tight your curls are, you can go from curly to smooth in no time. Curly hair is naturally dry and prone to damage, so straightening your strands needs to be done very carefully.
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.
When we are stressed we produce the hormone Cortisol. High levels of cortisol can bring about changes in our body. It can shorten the Anagen or growth phase of the hair cycle. When this happens, it causes more hairs than normal to move from the anagen phase to the telogen or shedding phase.
Your Hair Needs Moisture or Protein
Your hair may be in need of a strong dose of moisture or protein. If your hair is not healthy and balanced, the curl pattern will suffer. Moisture and protein are very important for hair health, especially for more fragile curls.
The bad news: Once hair is burned, there is no way to fully repair your curl pattern until new hair grows in to replace it. Unfortunately it takes only one bad burn to fry your hair, but repeated heat exposure has the same effect.
While the versatility is great, the heat can cause you to lose your natural pattern over time. Eventually, you may even realize that your curl pattern is completely damaged or that your hair won't curl at all.
You are turning your curling iron heat up too high
There can be too much of a good thing. When you use an extreme amount of heat (e.g. 400+ degrees) on the hair to curl it, you may actually make the cuticle (the hair's outer layer) slam shut and flatten so much that it refuses to hold a bend.
“As every inch of hair grows, the hair pattern changes.” And since hair grows at a rate of four to six inches per year, that's a ton of change. “Our curls tend to drop or loosen as we get older because of one thing: gravity,” Troisi writes.
Heavy products applied after your cut may be weighing your hair down, causing it to look less curly. Try washing those out and styling as you normally would to see if you gain any curl back. Removing length could also remove ringlets, which leaves your hair with a straighter look.
Short crop length (six inches) at one year. Medium length, hair touches the nape of neck when wet (ten inches) at one and a half years. Shoulder length (twelve inches) at two years. Reaching the middle of your back (sixteen inches) at two and a half years.
Well, hard water can leave curly hair coated in a film of mineral buildup which can weigh curls down, stretch them out and cause them to fall flat. To restore the spring back into your curls you need to remove these minerals and that's where Color Wow's Dream Filter comes in to play.
At times of great hormonal shifts, like puberty, pregnancy and menopause, many strange things can happen to the human body. Skin texture can change, the ability to put on or lose weight might not be the same and, sometimes, hormonal changes can literally curl (or straighten) your hair!
Yes, many people notice a change in their hair's texture as they age. Curly hair can become straighter, while straight hair might develop a wave it never had before.
For example, if you have thick hair, you'll want to use a higher heat setting than someone with thin or fine hair. Adjusting the heat setting to your hair type will ensure that your curls hold!" Speaking of a proper heat setting, Potempa says digital is the way to go.
That's because high-porosity hair has large gaps and holes in the cuticle, making it very easy for the hair to lose moisture; and when moisture evaporates from high-porosity hair, it renders products less effective—which results in loose, frizzy curls.
Curly and wavy hair is completely uninhibited by societal pressure. Your curls will laugh in your face when you try to change them and they will declare themselves a wild force of nature. This is hot! And that is why so many people want to make babies with people with curly 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. This change to your hair can be initiated by many factors such as genetics, lifestyle and stress.
Aim to wash your curly hair anywhere from one to five times per week, recommends Lindsey Little, the owner of Lume Salon in Boston.
