What is K18 AirWash™ Dry Shampoo Travel Size?

K18 AirWash™ Dry Shampoo Travel Size is a 47ml non-aerosol dry shampoo designed to refresh the hair and scalp between washes. Powered by patented odorBIND™ smart-release biotechnology, the formula eliminates odours, reduces excess oil and keeps working for up to 3 days.

Translucent, porous microbeads absorb excess oil and sweat without leaving behind starchy buildup or a visible white cast. The concentrated formula leaves hair feeling clean and fresh without a gritty or heavy finish.

Who is it best for?

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

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

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

What problem does it solve?

Excess oil, sweat and unwanted odours can build up between washes, leaving hair and the scalp feeling less fresh.

K18 AirWash™ Dry Shampoo combines translucent microbeads with odorBIND™ smart-release biotechnology to target these concerns. The microbeads absorb excess oil and sweat, while odorBIND™ recognises, traps and eliminates odour-causing molecules on contact.

The formula also helps balance scalp sebum and control excess oil production over time. K18 states that the highly concentrated formula continues working for up to 3 days, helping you go longer between washes.

How to use K18 AirWash™ Dry Shampoo

Shake well before use. K18 recommends shaking 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 start with 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 first 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 the hair with an in-shower shampoo.

Millies Expert Advice

Less is more with 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 Travel Size right for me?

Choose this if: you want a 47ml dry shampoo to refresh your hair and scalp between washes, absorb excess oil and sweat, tackle unwanted odours and avoid starchy buildup or visible white cast.

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. K18 describes AirWash™ as a refresher between washes rather than a styling product.
