Humidity: 90%. Your plan: air dry your hair. The odds of zero frizz? Well—it’s complicated. 

While perfectly sleek strands aren’t really in the cards during peak humidity, that doesn't mean you have to surrender to the uncontrolled poof. Here's how to air dry like you mean it, even when the weather is wreaking havoc on your hair.

what causes frizz when you air dry?

Frizz happens when the outer layer of your hair (the cuticle) lifts up and lets moisture from the air in. Curls + coils are naturally more porous + the more damaged your hair is, the more porous it becomes (this is what makes it more likely to puff, fuzz, or do that half-wavy-half-straight thing no one asked for).

So, the solution isn’t just to seal the hair externally—it’s to strengthen and smooth from the inside out.

how to air dry like a stylist

1. repair before you style

Preventing frizz starts in the shower. If your hair is damaged, it’s more likely to absorb moisture from the air as it dries. That’s where structural repair makes a big difference. Prep hair with detox shampoo, skip conditioner, and apply the molecular repair hair mask to towel-dried hair. 

Let it sit for 4 minutes for the K18PEPTIDE™ to penetrate hair’s innermost layers before applying anything else. This step reverses damage at the molecular level, helping to restore your hair’s internal structure so it dries stronger, smoother, and more resistant to frizz.

2. be gentle when drying

Speaking of towel-drying: Skip the aggressive towel rub. Friction raises the cuticle and causes more frizz, especially when your hair is soaking wet and very vulnerable. Instead, use a microfiber towel or soft cotton T-shirt to gently blot and squeeze out excess water.

3. set your style while it’s wet

How you position your hair while it dries makes all the difference in the final result. Once you've detangled, take a few extra seconds to set your hair in the direction you want it to dry.

For straighter styles, use your fingers to smooth hair into place and tuck behind your ears. For waves and curls, scrunch gently upward to enhance your natural pattern, or twist sections away from your face for more definition. The most important thing to remember about curls and coils is once your hair is set…do. not. touch. it. It’s all too tempting to try to scrunch out your curl cast or play with your curtain bangs before your hair is 99% dry, but you will see a massive difference in your frizz levels when you keep your hands out of your hair until it is fully dry. 

4. consider your environment 

Where you dry matters almost as much as how you dry. Avoid hanging out in super humid rooms like the bathroom right after your shower. The excess moisture in the air will make its way into your hair before it has a chance to set.

If it's a particularly humid day, consider turning on a fan or air conditioner in the room where you're air drying. Moving air helps water evaporate from your hair more evenly, which means less frizz.

5. seal and smooth with oil

The key to a great air dry finish is locking in moisture before the humidity gets to it. Unlike traditional oils that just sit on the surface, K18's weightless molecular repair hair oil actually strengthens and repairs damage while reducing frizz (for a full 24 hours*) at two levels of the hair fiber. To get the strengthening benefits from the K18PEPTIDE™ wait 4 minutes before styling, and enjoy that 104% increase in shine.

aim for ease, not perfection 

Will air drying ever give you that glass-like, just-stepped-out-of-the-salon finish in the middle of summer? No, and aiming for that will only bring you down.

However, air drying is an opportunity to get to know your natural texture and embrace all its quirks (plus, who doesn't love an effortless look in the summertime). With these simple steps, you can level up your air dry without a time-consuming routine. 

In short: the healthier your hair, the more shine and bounce it will have, even when all you have time for is a quick wash + go. 

The secret to a perfect air dry isn't fighting nature and your natural texture—it's giving your hair what it needs to look its best, whatever the forecast.
