Consumer flat irons can sometimes be equipped with different heat settings that can go up to degrees or more. According to the AAD , exposing the hair to such high temperatures from to degrees for just five minutes can cause harm to your hair.
When a hot flat iron is applied to damp or wet hair, it can cause damage at an even lower temperature. This can also happen when your hair has been bleached, permed or dyed, so just be careful. This allows light to pass through it and gives it an internal glow translucent center , and an external, reflective shine smooth cuticle.
Excessive heat damages both of these layers. But on the flip side, Dr. Krant says that people with thicker, curlier hair are using more heat to achieve their results which increases the risk of damage as well. She adds, "The actual damage that results is the same: dull, brittle hair with no shine, and, at worst, damage to scalp and hair follicles.
Color-treated hair is also less tolerant to excessive hair straightening, and as we age, Dr. Mirmirani adds that our locks' tolerance to heat also decreases "probably because the hair is finer and thinner. While thicker, coarser hair can resist breakage better than fine or damaged hair, according to Cunnane Phillips, this creates a tempting desire to straighten and tame this hair type daily.
It can become quite a vicious cycle. Try to limit the use of straighteners to once or twice a week," she says. Persistent heat and chemical damage to hair and scalp can eventually lead to permanent hair loss. One of the biggest takeaways from Dr. Krant's advice is to never underestimate the damage you do, and to do your best to keep heat-styling devices and chemicals away from the scalp -- even if it might mean having slightly fuzzy roots.
There is also a delayed effect, so it can be months to years after the damage is done that the hair no longer grows well," she says. Trying to heat style hair when it's wet will lead to steam damage, which is like boiling the hair from the outside.
Krant breaks down excessive heat styling in two parts: "First, it literally boils the moisture in the center of the hair shaft, cracking the smooth walls of the medulla and creating bubbles within the shaft that break and disrupt the flow of light imagine a cracked prism preventing a uniform rainbow from being created.
Second, the cuticle, pushed outward irregularly by these bubbles, also cracks and splits, losing its smoothness and becoming rough and more like shingles, which disrupts the reflective sheen. Wet hair is like a loose spring which stretches too easily and then breaks before the coil can snap back, so excessive tension can lead to more split ends and broken strands.
Vibrating flat irons use a combination of heat and vibration to glide smoothly over the section of the hair. Tiny vibrations reduce pulling and snagging, allowing for easier release of hair.
This makes the heat straightening process faster and reduces the possibility of heat damage or breakage. This type of flat iron works best on thick, coarse hair.
Steam flat irons release steam from a built-in water tank to moisten the hair during straightening, so they are less likely to burn your hair than regular straighteners.
Use your flat iron moderately and adjust the heat level according to your hair texture and condition. Fine hair requires lower temperature settings than thick or coarse hair. Color-treated and chemically processed hair is more prone to heat damage than healthy hair. Thicker hair can handle temperatures ranging from to degrees.
For curly hair, it is advisable to stay below degrees Fahrenheit. To minimize heat damage, always use a heat-protectant before straightening your hair. These products fortify the hair with moisture and form a protective layer to defend hair against heat damage. Select a product formulated with natural and organic ingredients, as it will stay in your hair.
A heat protector should be applied to clean, damp hair in order to be absorbed into the hair shaft. Using these eight techniques will allow you to straighten your hair without destroying it.
Starting the process in the shower will allow your hair to take to straightening easier. This means less time that your hair needs to be under the heat , according to professional hair-care brand Schwarzkopf. This allows you to have better access to each section of your hair, preventing you from having to go over the same pieces again and again.
Instead of reaching behind the top layer of your hair, clip it up to allow for easy reach to your bottom layer. This causes a bubbling and buckling of the cuticle that appear as tiny hair blisters under magnification. Just spray on or rub in a little right before you straighten your hair to maximize its effects.
