what makes it different

High-performance, future-forward clean.

This non-aerosol dry shampoo with patented odorBIND™ smart-release biotechnology eliminates odors, absorbs oil, and keeps hair feeling fresh for up to 3 days.**
how to use

Non-aerosol format may feel slightly damp on application but won't disturb you style.

1. Shake well for at least 5 seconds before use.

2. Hold bottle 4-6 inches from scalp (closer to 4 inches for coily textures).

3. Section hair and apply 1 spray per section, less is more.

4. Massage in, then brush or style as usual.

5. Replace cap when not in use to protect nozzle.

Tips:

  • If hair feels gritty or powdery, you may have used too much, brush through or reset with an in-shower shampoo.
  • If nozzle clogs, it's likely from air exposure or insufficient shaking. Shake again and try spraying.

Reviews

Bad product and no response from company

"I left a 1 star review below where I was told to email K18 on the email provided. Have literally not had any response. Quick to respond to a bad review and act the customer service part, but won’t actually provide customer service behind the scenes."

— Alex a. (1/5)

Best Dry Shampoo ever used

"I have extremely fine hair which soaks up natural oils and needs to be washed daily. This dry shampoo doesn’t leave a horrible white residue like the others. It dries the oil and thickens my hair beautifully. I was surprised at how good it is and I have tried so many. It feels fantastic. Just have to follow directions and allow to dry before brushing through. It is expensive but you don’t need much snd it lasts."

— N. N. (5/5)

Waste of money

"Cannot believe I dropped $85 on this. I fell into the hype. I cannot even brush my hair once I’ve put this in. It has a huge build up, feels the same yucky residue as any other dry shampoo, and becomes knotted, thick and gross immediately. Doesn’t cover greasy hair any more than your typical supermarket dry shampoo. I’ve even got a demo from hairdressers at hairhouse warehouse. I wish there was a “get your money back” if you don’t like it on this product, but I think they know all too well their product sucks."

Stopped working after 3 uses

"Stopped working after 3 uses. Nothing comes out of the nozzle Have shaken it like the instructions. I used cash and didn’t get a reciept What a waste of $85"

— Sam C. (1/5)

Game changer!

"As someone who uses dry shampoo every day that I don’t wash this has been a game changer. It works and it lasts, you don’t need much and it lasts forever, I’m spending less money using k18 airwash then what I used to spend on regular aerosol dry shampoos"

— Trish (5/5)

Great if used correctly!

"Game changer for me! However be patient. Let the product dry before applying extra sprays or your hair will end up all dry. If you put the right amount of product, the result is great!"

— Diane (5/5)

Not worth the money

"This product is far to expensive. Ridiculously expensive. I am outraged at myself for paying this much money for this product. It is no better than *cheaper (still too expensive for what they are) supermarket brands. Left hair straw like, didn't effectively mask oil and caused breakage. I'm looking into making my own for my own personal use. I will pay for quality and longevity but Im sick of being ripped off by corporations."

— Em (2/5)

Doesn't feel nice

"Does make your hair look very clean and last for days. But does not make it feel nice at all. Very dry like hay. When you run your fingers through your hair, it gets stuck and tangled. When putting your hair up, gets all stiff and not smooth."

— Kaily (3/5)

Not worth the money at all

"Not nice texture and makes the hair incredibly tangled and messy."

— Jessica U. (2/5)

"Its a heavy dry shampoo that also gives texture. Juat aomething i need to get used to. Does make my scalp itchy."

— RL (4/5)
