K18 AirWash™ Dry Shampoo is a non-aerosol dry shampoo for use between washes, here in the 47 ml size. It absorbs excess oil without visible residue and goes on dry hair only, section by section. It also comes in 118 ml.

What it does, as the brand describes it

The core is simple: it absorbs excess oil without visible residue. K18 says its odorBIND™ technology eliminates odours and leaves a fresh scent, which the brand says lasts up to three days. The brand also says the formula extends the time between washes up to three days. For the scalp the promise stays modest: a fresh feel on the scalp, as the formula takes up excess oil.

Key ingredients

From the ingredient list, by position

• Alcohol Denat.: entry 2
• Silica: entry 3
• Arginine: entry 5
• Sodium Hyaluronate: entry 7
• Glycerin: entry 8

Water (Aqua) opens the list. Fragrance (Parfum) sits near the end, followed by four named fragrance allergens: Linalool, Hexyl Cinnamal, Limonene and Benzyl Alcohol.

What to expect

The lever is the amount. Work section by section, start low and add only where the hair still needs it. Massage each section in before you brush or style, so the product spreads. On application the spray can feel a little damp; that comes with the non-aerosol format.

Who it is for

• Clients between washes who want to push back the next shampoo.
• Salons selling at the desk: a dry shampoo with a short, clear routine to explain.
• Routines with the K18 Molecular Repair Hair Oil: the brand's FAQ says AirWash™ can be used alone or before the oil.
• Anyone who prefers a non-aerosol format.

Who it is not for

• Wet hair: it is meant for dry hair.
• Anyone who reacts to one of the four fragrance allergens named on the list.

How to use

The published directions, translated from Dutch. The spray distance is left out (…): the brand gives different figures for it.

Method A: the published directions

1. SHAKE WELL. The non-aerosol format can feel slightly damp, but it will not disturb your style.
2. Hold the bottle … from the scalp for an even distribution.
3. Divide the hair into sections and apply only 1 spray per section. Less is more. Add more only if needed.
4. Massage in and brush or style as usual.

If the hair feels powdery, you may have applied too much product. Brush the hair to distribute the product.

Where it fits in the K18 range

The brand's FAQ places it on dry hair, on its own or before the K18 Molecular Repair Hair Oil. For the wash itself the range has the K18 DAMAGE SHIELD pH Protective Shampoo and the K18 Peptide Prep™ Detox Shampoo, each with its own directions. In the K18 styling line it sits next to HeatBounce™ and AstroLift™. Browse the K18 styling category or the full K18 brand page.
