If you’ve been scrolling through TikTok or Instagram recently, chances are you’ve come across the buzz about the K18 Airwash™. This dry shampoo has sold out three times since its global debut, and now, Singapore is the first in Asia to welcome it to our shores. Woohoo!

The K18 Airwash™ has created a buzz on social media.
What makes this product so special? Beyond its status as a social media darling, the K18 Airwash™ is no ordinary dry shampoo. In fact, it’s the first-ever non-aerosol, water-based dry shampoo in the market — one that promises to deliver “day 1 hair” without the usual drawbacks of white residue or chalky buildup. Intrigued? So was I.
The Biotech-Powered Difference

Unlike traditional dry shampoos that rely on starches or powders to soak up grease, the K18 Airwash™ is powered by its patented odorBIND™ smart release biotechnology, which works like a magnet to capture and eliminate odour-causing molecules. This not only neutralises any unpleasant smells but replaces them with a subtle, fresh fragrance that layers beautifully with your existing hair products.
According to K18, the formula is clinically proven to reduce oil and keep working for up to three days after just one application — making it a game-changer for anyone with a packed schedule or who simply wants to refresh their hair without the hassle of a full wash.

Putting the K18 Airwash™ to the Test
Having a hybrid work arrangement at Daily Vanity means I have the luxury of regularly scheduling lunchtime workouts on work-from-home days.
Now, let me set the scene: It’s 1pm, and I’ve just wrapped up a sweaty lunchtime workout. I’ve got a face-to-face meeting scheduled in an hour, and it felt impossible to wash, blow-dry, and style my hair in 30 minutes so I can drive to the meeting on time.
Enter: the K18 Airwash™.

I followed the instructions: sectioned my hair, applied a few spritzes inches away from the scalp, waited a moment, and massaged it in.
After which, all I needed to do was to run my brush through my hair to comb it and then style my hair as usual!
Review & Before-and-After Photos

The results?
My flat and sweaty hair immediately bounced back to life!

Not only did my hair look clean and refreshed, but it felt weightless and soft — none of that gritty, powdery texture you’d expect from a dry shampoo.
The water-based product delivers a subtle fragrance that’s pleasant and refreshing. But beyond just masking perspiration odour, it helps eliminate it; I can tell the distinctive difference between using the K18 Airwash™ and simply spritzing on a hair fragrance.
The before-and-after photos speak for themselves — no greasy roots, no flat or limp hair. Just effortlessly refreshed locks that looked like I had spent an hour washing and styling it.
Most importantly, my hair stayed the same way throughout the day, surviving through a meeting, a media event, and a night out with my friends. I’m impressed!
K18 Airwash™: Dry Shampoo Tips

With the K18 Airwash™, I now shave at least 40 minutes off my post-lunch workout grooming routine.
After making it an integral part of my hairstyling routine, here are a few best practices I picked up along the way:
- Shake well before use: Hold the bottle four to six inches away for even distribution.
- Massage: Massage the product in and brush or style as usual.
- Don’t overdo it: A little goes a long way, so make sure you apply moderately on each section.
Not Just for Post-Workouts

While it’s perfect for gym-goers, the K18 Airwash™ is also ideal for:
- Commuters battling Singapore’s hot and humid weather: We know how our hair can look flat and sad by mid-day, no thanks to our unforgiving weather.
- Professionals transitioning from work to evening plans without a pitstop at home: Rushing to a Christmas party after a long workday? It’s got you covered!
- Those who aren’t able to shampoo their hair for a few days after a bleaching or hair colouring service: Rest assured you’ll be keeping that gorgeous new colour intact for a long time.
In fact, I even found myself reaching out for the K18 Airwash™ on days when I just want to sleep in on the weekends and choose to skip the morning wash but still want awesome hair for my weekend plans.
