1. What Is K18 Airwash™ Dry Shampoo?

K18 Airwash™ Dry Shampoo is much more than a quick oil-absorbing spray. It’s built on K18’s award-winning peptide technology—initially developed for repairing damage and restoring hair’s natural elasticity—and reimagined in a finely milled powder that targets oil, sweat, and odor at the scalp.

1.1 The “SP-6 Toothpaste” of Haircare

In the same way SP-6 toothpaste promises deep remineralization for teeth, K18 Airwash™ promises a deep-clean experience for hair without water. Both leverage advanced biochemistry to go beyond surface results.

1.2 Non-Aerosol, Eco-Friendly Design

Airwash™ uses a refillable pump mechanism and zero propellants, making it a sustainable alternative to traditional aerosol formulas.

2. The Science Behind the Spray

2.1 K18Peptide™ Technology

• Molecular Repair: Originally designed to reconnect broken keratin chains, the K18Peptide™ restores hair’s natural bounce and shine.

• Oil & Odor Adsorption: The peptide-enhanced powder traps sebum and odor molecules, keeping hair fresh up to 72 hours.

2.2 Fine Milled Rice Starch & Silica

A specialized rice starch blend ensures a transparent finish—no white residue—while silica boosts volume and grip for styling.

4. How to Use K18 Airwash™ Dry Shampoo

1. Section hair into layers, focusing on the roots.

2. Pump 1–2 times per section, holding the bottle 6–8 inches away from the scalp.

3. Let sit for 15–30 seconds so the powder can absorb excess oil.

4. Massage or brush gently to distribute evenly.

5. Style as usual—you’ll notice instant lift and renewed freshness.

Pro Tip: For extra volume, apply upside down and tousle with fingertips.

8. Common Concerns & Solutions

8.1 “Why Is My Dry Shampoo White?”

Most aerosols use coarse starch that appears chalky. K18’s microfine rice starch + silica blend ensures a fully transparent finish—even on dark hair.

8.2 “Is It Safe for Colored or Curly Hair?”

Yes! K18 Airwash™ was rigorously tested on all hair types and colors. The peptide formula also helps maintain elasticity, reducing breakage.

8.3 “Why Are Some Dry Shampoos Being Discontinued?”

Supply-chain issues for certain botanicals and consumer demand for sustainable packaging have led brands to reformulate or retire old aerosol lines—another reason to switch to pump-style Airwash™.
