K18’s dry shampoo completely transformed my haircare routine – I’ve found a dupe that’s £42 cheaper

I’VE tried so many dry shampoos over the years, so it takes a LOT for me to call one a game-changer. K18’s Airwash dry shampoo genuinely blew me away when I tried it for the first time, but with a steep £48 price tag, I can’t justify repurchasing a new one every few months. I found a dupe that’s just as good as the expensive version Got2b Get Fresh Dry Shampoo, £5.75 I used to love an aerosol dry shampoo, but using one across several days resulted in product build-up and hair that still feels greasy.

Got2B Get Fresh dry shampoo: Quickfire Q&A How much is it? Got2B’s Get Fresh dry shampoo costs £5.75 at Boots, while K18’s version is £48. Who’s it best for? K18 AirWash fans looking to save money, beauty fans in need of fresh hair for longer, dry shampoo lovers that find aerosols irritate their scalp. What we loved: Gives hair a fresh feeling for days, feels lightweight, affordable price, doesn’t leave marks on clothes. What we didn’t love: It’s marginally less powerful than K18’s dry shampoo. Got2B’s Get Fresh Dry Shampoo has (almost) all of the strengths of the high-end version, but for just £6. It’s practically weightless in the hair, it doesn’t leave the white cast (common with aerosols), and it smells lovely. K18’s dry shampoo is a game-changer – but I couldn’t justify the price K18 Biomimetic Hairscience Airwash Dry Shampoo, £48 Most importantly though, it completely revives my hair for days after it’s been washed. Most read in Shopping I try to keep my hair washes to twice a week, which can sometimes feel like a struggle. Liquid dry shampoo has completely transformed my routine, as the mist feels like it’s actually lifting away oil and odour, rather than just masking it. It still adds some slight texture (which is good for extra volume), but it does make my hair feel dry when used for consecutive days. This is to be expected though, as dry shampoo isn’t there to replace hair washing, but to extend the period between washes. While K18’s version is slightly more powerful than Got2b’s, the fact I can spray it generously without feeling like I’m wasting an expensive product makes up for it. The affordable version has the same benefits but with an affordable price tag Got2b Get Fresh Dry Shampoo, £5.75 The expensive version is also slightly smaller at 118ml, while Got2b has a generous 150ml. K18 sometimes leaves white dots on clothing (which are easy enough to remove), while the Got2b dupe can be spritzed freely without repercussions. If I’m in severe need of hair revival, I’ll sometimes follow up with an aerosol for an extra touch of volume (read my roundup of the best dry shampoos for my favourites). Dry shampoo will never replace hair washing, but Got2b’s Get Fresh has done an incredible job at extending my washes.

The Verdict K18’s Airwash Dry Shampoo is up there with my favourite products of 2026, but Got2b’s dupe is the one I’ll be repurchasing. It has all the same strengths (refreshing the hair, removing odour, a lightweight consistency), but without the hefty price tag. Liquid dry shampoos are far more effective at keeping hair fresh for longer, and both options have meant I can go longer without washing my hair.
