K18 AirWash™ Dry Shampoo 118ml

Refresh oily roots and extend the time between washes with K18 AirWash™ Dry Shampoo 118ml, a high-performance non-aerosol dry shampoo that absorbs excess oil and sweat, eliminates odor and leaves the hair and scalp feeling genuinely fresh — without the chalky white residue or heavy, powdery buildup associated with many traditional dry shampoos.

Instead of relying on starch-heavy powders, AirWash™ uses translucent porous microbeads that act like tiny sponges to absorb excess oil while remaining virtually invisible in the hair. K18's patented odorBIND™ biotechnology recognizes, traps and eliminates odor-causing molecules on contact, helping keep hair fresh for up to 3 days.

The formula also contains biotech-derived Mediterranean microalgae to help balance scalp sebum and control excess oil production over time. The result is hair that looks and feels cleaner, lighter and fresher while retaining natural movement — even after workouts or several days between washes.

What Does K18 AirWash™ Dry Shampoo Do?

AirWash™ is designed to solve three of the biggest problems people experience with traditional dry shampoos:

Oil → Odor → Powdery Buildup

Its translucent microbeads absorb oil and sweat without leaving the typical starch residue behind.

At the same time, odorBIND™ smart-release biotechnology recognizes and captures odor-causing molecules, helping eliminate unwanted smells rather than simply masking them with fragrance.

Finally, Tetraselmis Suecica Extract, a biotech-derived Mediterranean microalgae, helps balance the scalp and control excess oil production over time.

This makes AirWash™ particularly useful for people who want to wash their hair less frequently without sacrificing a genuinely clean look and feel.

What's the Best Dry Shampoo for Oily Hair Without White Residue?

Traditional dry shampoos often rely heavily on powders or starches that absorb oil but can leave hair feeling chalky, stiff, gritty or visibly white, particularly on darker hair.

K18 AirWash™ takes a different approach.

Its translucent porous microbeads absorb excess oil without leaving visible white residue or starchy buildup.

This isn't only brand positioning. In independent 2026 testing, The Independent selected K18 AirWash™ as its best overall dry shampoo, specifically praising its ability to revive oily roots without the stiffness, chalkiness and scalp buildup commonly associated with dry shampoos.

How Can I Keep My Hair Fresh for Longer Without Washing It Every Day?

If your scalp becomes oily quickly, AirWash™ is designed specifically to help extend the time between wet washes.

K18 reports up to 3 days of oil and odor control from its concentrated non-aerosol formula.

Because it tackles both visible oil and odor, it can be especially useful after workouts, during busy weeks, when maintaining a blowout, or whenever you want to postpone your next shampoo without hair looking obviously coated in dry shampoo.

It doesn't replace proper shampooing indefinitely. When buildup eventually develops from styling products, oils or repeated dry-shampoo use, reset the scalp with a proper cleanse.

Does K18 AirWash™ Work on Dark Hair Without Leaving a White Cast?

Yes. This is one of AirWash™'s strongest advantages.

The oil-absorbing microbeads are translucent rather than an opaque white powder, and K18 specifically formulates AirWash™ to absorb oil without leaving a visible white cast.

This makes it suitable across hair colors and textures, including darker hair where conventional dry-shampoo residue can be particularly noticeable.

Wash™ dry shampoo | K18Hair

Shake vigorously for at least 5 seconds before every application.

Section the hair.

Hold the bottle approximately 4–6 inches (10–15 cm) from the scalp. For coily textures, K18 recommends applying closer to approximately 4 inches.

Apply just 1 spray per section.

Massage into the scalp, then brush through or style as usual.

Add more only if necessary — AirWash™ is highly concentrated.

Important Application Tip

Because AirWash™ is non-aerosol, it can initially feel slightly damp.

That's normal.

Allow it to dry down rather than continuing to spray more product. K18 reports that 93% of participants agreed it did not revert their hairstyle.

If the hair feels gritty or powdery, you've probably applied too much. Brush through to redistribute the product or wash with shampoo to reset the hair
