A keratin treatment can eliminate your frizz, reduce your time spent blow-drying, and make your hair look like it stepped right off a Hollywood celebrity and onto your scalp. But getting a keratin hair treatment isn’t as simple as popping into the salon and popping back out. There’s a lot to consider beforehand. Read along as we answer everything you need to know about the popular salon service.
As explained in our what is keratin guide, a keratin treatment is a hair-smoothing treatment performed in salon or at home. We’re going to focus on the more complicated salon treatment in this guide.
The goal of a professional keratin treatment is to smooth hair and eliminate frizz. It does this by using a combination of chemicals and heat to break the hair’s bonds and lock strands in a straighter position—without completely straightening hair.
The entire process lasts 90 minutes or longer, depending on how long your hair is.
Typically, keratin treatment results last around 2– 3 months. But they can last up to five months depending on the type of keratin product used and aftercare.
Not completely. According to numerous stylists, the treatment relaxes curls slightly but doesn't completely get rid of them. If your hair is wavy or frizzy, the treatment will likely get closer to straightening it, but if you have bountiful curls, your curls will simply soften. If you have tight coils, you’ll experience more elongated coils.
According to many stylists who specialize in keratin hair smoothing, you should be able to curl your hair after the treatment with a round brush and blow-dryer. The treatments shouldn't reduce your overall hair volume, and your hair should remain malleable to your styling touch.

A keratin treatment may contain keratin, but keratin isn’t what actually smooths hair. That’s because keratin is really just a marketing buzzword used to refer to a variety of professional smoothing treatments.
Chemicals like formaldehyde and the formaldehyde-alternative glyoxylic acid are what smooth hair. Formaldehyde offers more dramatic results, but is a suspected carcinogen.
According to the Environmental Working Group, some formulas claim to be formaldehyde-free, but actually contain methylene glycol, a solution of formaldehyde and water that release formaldehyde (a gas) when heated. That’s why some salons will give clients and stylists a mask to wear during the keratin treatment.
It’s possible to get a smoothing treatment that is formaldehyde-free and uses glyoxylic acid instead. Look for Goldwell Kerasilk, Trissola Solo, Cezanne Perfect Finish, and Supersilk Smoothing System.
