K-18 Airwash Dry Shampoo Is the Closest Thing You’ll Get to Freshly Washed Hair

Shocked and inspired, I immediately emailed K-18 to get my own sample. Surely, it couldn’t be real. A dry shampoo that leaves your hair looking freshly washed with not a hint of white cast? Inconceivable! Sorcery! I had to try it for myself.

A few days later, K-18 sent me their “biggest innovation” to date. According to the brand, AirWash features “smart-release biotechnology” that allegedly eliminates odor-causing molecules and “translucent microbeads” that absorb oil and, according to the brand, leave no starchy buildup or white cast on strands. The formula also includes “biotech-derived mediterranean microalgae” that AirWash says “helps balance the scalp and control excess oil production over time” to promote scalp health and minimize buildup.

AirWash claims its product will also deliver touchable, weightless hair for up to three days. And the cherry on top? It’s earth-friendly and non-aerosol.

As it turns out, the word “innovation” was no exaggeration. After months of using AirWash, I’ll never go back to another product. I’ve never used a dry shampoo that revitalizes my hair and provides the look and feeling of being freshly washed like AirWash does.

If that wasn’t enough, it actually delivers on results for “up to three days.” On day two, my hair still has volume and body and requires no touch ups of product. By day three, my roots start to go a little limp, but overall, my hair looks wearable enough to get me through the day.

The scent is a clean subtle smell that isn’t noticeable. As someone who prefers unscented hair products, it’s the biggest turnoff when dry shampoo reeks of sweet florals—especially since I need to go to town with application. Something I can do with AirWash, because it feels astronomically lighter than the most other cult-favorite dry shampoos.

Before getting started, I give the bottle a good shake to activate the formula. To apply, I lift section by section and spray four to six inches away at the root, then let the product sit for a few seconds before rubbing in with my fingers. Finally, I use a hair brush to distribute evenly and to make sure any excess is absorbed.

Is AirWash 100% weightless? No, but keep in mind that I use a lot. K-18 advises applying sparingly but old habits die hard. With a heavy hand, you can certainly feel a bit of grit and buildup.
