Best for: All hair types, textures and styles that need a fresh, clean feel between washes, particularly when excess oil, sweat or odour is a concern.

What is K18 AirWash™ Dry Shampoo?

K18 AirWash™ Dry Shampoo is a non-aerosol dry shampoo designed to refresh the hair and scalp between washes. Powered by patented odorBIND™ smart-release biotechnology, it clinically eliminates odours, reduces oil and keeps working for up to 3 days.

Unlike traditional powdery dry shampoos, AirWash™ uses translucent, porous microbeads to absorb excess oil and sweat without leaving starchy buildup or a visible white cast. The lightweight formula leaves hair feeling clean and fresh without a gritty or heavy finish.

Who is it best for?

K18 AirWash™ Dry Shampoo may suit you if your hair:

• becomes oily between washes
• needs refreshing without an in-shower shampoo
• needs excess sweat and oil absorbed
• develops unwanted odours between washes
• is prone to visible residue or white cast from traditional dry shampoos
• needs a clean feel without heavy or gritty buildup

K18 states that AirWash™ can be used across all hair types, textures and styles, including protective styles and extensions.

What problem does it solve?

Between washes, excess oil, sweat and odour can leave the hair and scalp feeling less fresh.

K18 AirWash™ Dry Shampoo tackles these concerns by combining translucent microbeads that absorb excess oil and sweat with odorBIND™ biotechnology that recognises, traps and eliminates odour-causing molecules on contact.

The formula also helps balance scalp sebum and minimise excess buildup, while leaving hair looking and feeling clean. K18 states that its highly concentrated, non-aerosol formula can continue working for up to 3 days, helping you go longer between washes.

How to use K18 AirWash™ Dry Shampoo

Shake the bottle for at least 5 seconds before spraying.

Hold the bottle 4–6 inches away from the scalp for even distribution on most hair types, moving closer to 4 inches for coily textures. Section the hair and apply just 1 spray per section.

Less is more, so add additional product only as needed. Massage into the hair, then brush or style as usual.

The non-aerosol formula may feel slightly damp when applied but is designed not to disturb your style.

If your hair feels gritty or powdery, you may have applied too much. Brush through the hair to distribute the product or reset your hair with an in-shower shampoo.

Millies Expert Advice

Less is more when applying K18 AirWash™ Dry Shampoo. Shake the bottle thoroughly, section your hair and start with just one spray per section rather than applying a large amount at once. Massage the product in before brushing or styling as usual, adding more only where needed.

Is K18 AirWash™ Dry Shampoo right for me?

Choose this if: you want to refresh your hair and scalp between washes, absorb excess oil and sweat, tackle unwanted odours and avoid the starchy buildup or visible white cast associated with some dry shampoos.

Consider another product if: you're looking for an in-shower shampoo rather than a between-wash refresher, or your main requirement is a styling product rather than a dry shampoo. K18 specifically describes AirWash™ as a refresher between washes rather than a styling product.
