K18 AirWash Non-Aerosol Dry Shampoo Spray - 4 fl oz, Oil & Odor Eliminating, No White Cast

K18 AirWash is a non-aerosol dry shampoo that absorbs oil and sweat, eliminates odors with patented odorBIND™ technology, and refreshes hair and scalp for up to three days without leaving a white cast.

This lightweight formula was created to refresh hair between washes while staying gentle on color and texture. Instead of propellant, the non-aerosol spray delivers translucent microbeads that soak up excess oil and a biotech-derived Mediterranean microalgae ingredient that helps balance scalp sebum over time. The scent profile is intentionally subtle so your style isn't overpowered, and the concentrated formula means you can use less and reapply less often.

How does K18 AirWash remove odors without heavy fragrance?

AirWash uses odorBIND™ smart-release biotechnology to trap and neutralize odor-causing molecules rather than merely masking them with perfume. Because it targets the particles responsible for smell, the product leaves hair smelling neutral or subtly fresh without a heavy fragrance buildup.

• Patented odorBIND™ binds odor molecules for longer-lasting freshness.
• Biotechnology releases active ingredients gradually to sustain effect.
• Minimal fragrance to avoid competing scents with styling products.

Will K18 AirWash leave a white cast or residue on colored hair?

No—this dry shampoo features translucent microbeads designed to absorb oils and sweat without visible powdery residue. It’s formulated for all hair types and shades, so you can refresh roots and extend styles without worrying about starchy buildup or color dulling.

• Translucent microbeads absorb oil without visible powder.
• Non-starchy finish preserves color vibrancy and shine.
• Suitable for fine, thick, curly, straight, and chemically treated hair.

How should I apply this dry shampoo for best results?

Shake the bottle at least five seconds before use, section your hair, and spray one pump per section from 4–6 inches away. Massage the product into the scalp to distribute the microbeads, then brush or style as usual; the formula may feel slightly damp initially but dries without disturbing the hairstyle.

• Shake thoroughly to restore nozzle airflow and even distribution.
• Spray 4–6 inches from scalp, one pump per section, then massage in.
• Brush or finger-style; reapply sparingly because of concentrated formula.

Can this product help control oil production over time?

The shampoo contains a Mediterranean microalgae-derived ingredient that helps balance scalp sebum, supporting reduced excess oil with repeated use. While immediate oil absorption refreshes hair, the biotech ingredient is aimed at helping manage oil levels over time when used as part of a routine.

• Microalgae helps regulate sebum and supports scalp balance.
• Combines instant oil absorption with longer-term scalp support.
• Designed for routine use without harsh detergents or buildup.

Who is this for: K18 AirWash is for anyone who wants a clean-looking, fresher scalp and hair between washes—especially people with busy schedules, color-treated hair, or those who prefer low-fragrance styling products. It’s a good option for all hair types and textures when you need quick oil control, discreet odor removal, and a lightweight finish without aerosol propellant.
