Keratin—the protein that helps strengthen hair to prevent breakage, warm damage, and frizz—is vitally important for preserving solid and also healthy hair. But keratin straightening, the salon treatments that promise silky-smooth hair, have long come through significant wellness comes to. To obtain the breakdown of every little thing you have to understand around keratin therapies, we spoke with celebrity hairstylist and NatureLab Tokyo brand ambassador Andrew Fitzsimons, Eva NYC hairstylist T. Cooper, and celebrity hairstylist Annagjid "Kee" Taylor.

What Is Keratin?

Keratin is a structural protein discovered in our hair, skin, and nails. It"s additionally generally uncovered in styling products to assist strengthen hair—but the term keratin therapy is actually a misnomer. "Keratin treatments are a semi-permanent hair straightening therapy that smooth and also add shine to frizzy hair," claims Fitzsimons. How the therapies occupational is not via the usage of keratin, though.

To make hair straighter, a solution containing a formaldehyde derivative or (the much safer) glyoxylic acid is functioned with the hair to break the bonds and reseal them in a straighter position. The solution is then blow-dried and also sealed through a flat iron, and also the outcomes deserve to last all over from three to six months.

He says the treatments work well on the majority of hair kinds and recommends it for anyone that wants to cut out blow-drying or straightening their hair on a regular basis, minimize frizz, or boost shine.

How Does a Keratin Treatment Differ for Those With Natural Curls?

Taylor agrees with Fitzsimmons that keratin therapies work-related well on the majority of hair kinds. For curly hair in particular, it will totally smooth frizz and also add even more shine.

The treatment seals in the color, making it last longer and show up brighter.

Is Keratin the Same as a Japanese Treatment or Relaxer?

While comparable to other hair straightening therapies, keratin therapies are still distinctively various. Taylor describes that keratin therapies are a much less harsh choice to various other straightening therapies favor relaxers. "Keratin is great for those who have frizzy hair and also want permanent right and also smooth hair," she claims. "The chemicals with keratin are a tiny less harmful than those discovered through other straightening treatments, favor a relaxing therapy, which is extremely harsh."

"The main difference between a keratin treatment and also a relaxer is just how long they straighten the hair," defines Cooper. "A keratin treatment temporarily loosens your curl pattern, and also fades out over time. Your hair texture will certainly eventually return to its natural state. With a relaxer, that is not the situation at all. Relaxers break dvery own the molecular bonds in hair, and permanently straigh10s it." Since Japanese hair therapies and also standard relaxers permanently break your hair"s bonds using ammonium thioglycolate and sodium hydroxide, they are much even more efficient on coily hair—but additionally even more damaging. The growing-out phase will likewise be even more intense than via a keratin treatments, given that tbelow will certainly be a line of demarkation as soon as your organic texture grows back in.

Why Won"t Some Hairstylists Perform Keratin Treatments?

Part of the worry with keratin treatments revolve approximately among the ingredients found in a lot of standard salon formulas: formaldehyde. The Centers for Disease Control (CDC) specifies it as a colormuch less, strong-smelling gas that is generally offered to make structure materials, household assets choose glue and fiberboard, and provided as a preservative as soon as dissolved in water. In keratin treatments, it"s responsible for locking the hair right into that new straight and smooth place for months. But these treatments don"t actually contain formaldehyde, bereason, well, it"s a well-known carcinogen. What they contain rather is ingredients like methylene glycol, formalin, methanal, and methanediol, that release the carcinogenic compound when blended through water in the time of the therapy. So while the formula can technically be formaldehyde-cost-free, it"s not when combined via water.

This poses potential danger not just to you—but likewise the salon technicians that preform the therapies over and also over aobtain in enclosed spaces. "Some stylists refuse to execute keratin therapies, because tbelow is research that mirrors that ongoing use of formaldehyde overtime deserve to have actually some severe consequences," says Cooper. "The dangers deserve to be as minor as watery eyes and skin irritation, to as severe as cancer and also respiratory condition."

Undoubtedly, the CDC lists widespread side effects to formaldehyde exposure encompass sore throat, nose bleeds, and also scratchy eyes. The UNITED STATE Food and also Drug Administration (FDA) likewise advises about potential wellness dangers for those exposed and also notes that formulas and also commodities that case they"re organic, organic, or formaldehyde-cost-free might not be totally true. The FDA urges world to constantly read the label, ask hair professionals for an ingredient list, and to report any kind of and also all bad reactions.

These so-called keratin treatments have the right to likewise do most harm to your hair over time. Fitzsimons states bereason these therapy require high-warm to lock your hair right into location, he wouldn"t recommfinish it for those through super-fine or damaged hair. If you"re searching for a less-damaging, truly formaldehyde-free therapy, ask your salon if they use a treatment containing glyoxylic acid rather. They don"t straighten hair as dramatically (they"re even more for raising shine and also fighting frizz), but they"re also a lot safer.

How Long Do Keratin Treatments Last?

The cardinal dominance of keratin treatments is to stay ameans from water and ponytails for at leastern 3 days. You do not desire to risk producing a bend in your newly-straightened hair. Fitzsimons says the essential to keeping your therapy for as lengthy as feasible is utilizing a sulfate-cost-free shampoo on the days you wash your hair.

For those through organic curls, Taylor states not to wet your hair for three days. She additionally recommends using sodium chloride-free hair assets and also to wrap your hair in a silk or satin scarf (or pillowcase) to store the moisture locked in your hair as the therapy deserve to cause your hair to dry out faster. She says that therapies can last approximately six months, but does caution that it could influence your curl pattern permanently.
