"The Airwash Dry Shampoo. [...] I use one, two, three, four sprays and then use my hair dryer. So, I actually use this on wash day. And this is third day hair. This stuff works. It is the best dry shampoo I've ever tried. [...] Considering how fast I go through these versus this, the K18 is so worth it."

"This Airwash Dry Shampoo is a liquid dry shampoo and I doubted this so intensely. I don't know how they made a liquid dry shampoo that works as well as something like Living Proof without the white cast. I'll have to update on how long it lasts, since that's my biggest concern and why I tend to buy the powder dry shampoos, but I am wowed."

"Sometimes if I'm in a pinch, I will blow dry it to make it dry quicker. Other times I'll spray it before I hop into the shower for a body rinse and then by the time I'm out it's kind of set. But it really really works. It makes you feel like you just washed your hair, but also gives you a nice texture and grip and volume. It feels clean. [...] It's expensive, which is dumb, but it's really good. I've been very impressed by it."

"I'm not a big dry shampoo person, but I really like this one, and my wife likes this one, and all the women in my life are obsessed with this dry shampoo. The feedback on this has been so positive that they've convinced me that this is the best dry shampoo on the market. Currently 48 dollars."

"You just do like one little spritz into each section of your hair, wait like 30 seconds, massage it in, it's pretty magical. If I had to rate this on a scale of 1 to 10, I would give it like a 9.5, which is very generous for me because I'm really picky about things. But the only thing I dock points for is that when you spray it, it can leave a little bit of white residue, so if you're wearing dark clothing or you have dark countertops, you will see a little bit of that fallout."

"The K18 dry shampoo, I thought it was all hype. This is fantastic. I've been reaching for it more. I will basically just dry shampoo everything. You don't need a lot of this. Spritz, spritz, spritz. I will rub it through my hair. Basically get my hair looking clean and not oily. And then I will take a heated round brush and just brush out my front pieces."

"What I love about this so much is it's not aerosol. It's a little mister. [...] It's probably the best dry shampoo that I've ever used if I had to pick one. It's literally just like a little mist. If you're not careful and you don't mix it up well enough, sometimes you can get little white spots on your forehead. But [...] you basically just mist it and leave it for like a minute or something and then you can just brush it through. It just makes your hair look so clean."

"For me, I find that to be the worst because it literally looks like I have dandruff on my scalp, which is sometimes the reason why I don't enjoy using dry shampoo on my scalp. [...] No matter how much I shake up aerosol dry shampoos, that first spray always comes out with just a bit of white particles and flakes. But this one doesn't do that, and I'm obsessed with it."

"I was sent a K18 dry shampoo [...] and it actually worked really well for styling purposes. It's almost like a texturizer and for imparting a bit of lift at the roots. [...] It was not something that caked up on my hair at all. But my goodness is that product ever hard to spray. The nozzle is really hard to work."

What the evidence says.

Independent of what the gurus think, this is what the published research supports about the main active ingredients here.

Alpha hydroxy acids

Alpha hydroxy acids loosen the bonds holding dead cells at the surface. The evidence supports smoother texture and more even tone over time, and they can leave skin more sensitive to sun.

Humectants and emollients

Ingredients like these draw water into the surface layers and slow how fast it leaves. The evidence is for comfort, softness and hydration rather than for changing the structure of the skin.

Peptides

Peptides are short protein fragments meant to signal repair. The evidence for them is thinner than for retinoids or vitamin C, and it varies a lot by the specific peptide, so the category is more promising than proven.
