Using an Airstyler During and After a Keratin Treatment: Is It Safe?

Last updated: August 10, 2026 · 6 min read

Yes, you can use an airstyler after a keratin treatment, just not right away. For the first 48 to 72 hours, leave your hair alone: don't wash it, tie it up, or style it, so the keratin has a chance to properly bond. After that, you can go back to your normal styling routine, ideally on a low to medium heat setting, since too much heat dries out your hair and works against the treatment's effect.

Below you'll find how to get through the first few days without ruining your result, and which temperature feels best for your hair afterward.

Can you style your hair right after a keratin treatment?

No. For the first 48 to 72 hours after the treatment, your hair should hang as straight down as possible and stay dry. Don't wash it, and don't put it in a ponytail, headband, or clip, or tuck it behind your ears either: any kink or bend can set into your hair while the keratin is still bonding.

That means it's best to leave your airstyler or hairdryer alone during those first few days. Once that period is over and you wash your hair for the first time, you can go back to your normal styling routine.

What's the best temperature to style at after a keratin treatment?

A low to medium temperature is usually the best choice after a keratin treatment. Too much heat dries out your hair, makes it more brittle, and strips away the shine, exactly the effects the treatment was supposed to counter.

The Airstyler Pro Ceramiq has three settings: 35°C, 70°C, and 110°C. After a keratin treatment, 35°C or 70°C is generally enough for everyday styling, especially combined with a heat protectant. Save the highest setting for when your hair really needs it, rather than using it as your default.

Why does your stylist use such high heat during the treatment itself?

During the keratin treatment itself, your stylist often uses a flat iron at around 200 to 230°C. That heat is needed to let the keratin formula properly penetrate the hair shaft and seal the hair cuticle, which creates the smoothing effect. Each section of hair is passed over with the flat iron multiple times in the process.

That's a one-time, controlled process done by a professional, not something you replicate at home every day. For maintenance afterward, the opposite applies: use as little heat as possible to make the result last as long as possible.

Can you use an airstyler instead of a flat iron after a keratin treatment?

Yes, that can be a nice change. An airstyler like the Airstyler Pro Ceramiq dries and shapes your hair with warm air using a ceramic-coated barrel, instead of clamping your hair directly between two hot plates the way a flat iron does.

For hair that's just had a keratin treatment, that can feel more comfortable: you can style on a low setting and don't need to keep going over the same section with a hot plate. That doesn't replace your heat protectant though, which is still needed no matter which styling tool you use.
