7 Best Shampoos And Conditioners Of All Time, Ranked

When testing, we looked at everything from how clean and fresh our hair felt after washing to how quickly it became greasy again, as a shampoo/conditioner combo that only keeps hair feeling fresh for a day isn’t going to cut it. We also considered ingredients, and whether each formula suited different hair and scalp needs. And, of course, fragrance was important too – because when you’re washing your hair, you want it to smell good. Between us, we’ve tested well over 21 formulas, but these are the ones we’ve genuinely found ourselves reaching for time and time again.

Why you can trust me:

While I can’t claim to know everything there is to know about haircare, I’ve been a shopping writer for well over five years, which has given me plenty of time to test, trial and get to grips with hundreds of beauty products – including shampoos and conditioners. As part of my job, I regularly speak to haircare experts and trichologists to get their professional take, and I’m lucky enough to work alongside experienced Glamour beauty editors, too. Over the years, all of that hands-on testing, expert advice and working with people who know their stuff has taught me a lot about what actually makes a product worth recommending.

1. Best Overall: K18 Biomimetic Hariscience Damage Shield Shampoo & Conditioner Bundle

K18 Biomimetic Hairscience Damage Shield Shampoo & Conditioner Bundle

Why it’s worth it: If your hair feels brittle, dry or generally worse for wear from heat styling, colour or everyday product build-up, the K18 Damage Shield Shampoo & Conditioner Bundle is worth having on your radar. The shampoo contains the brand’s proprietary K18 peptide, which supports hair strength and helps reduce protein loss, making it suitable for colour-treated hair, including curls and coils, as well as fine or brittle strands. The conditioner also contains K18 peptide, alongside amaranth protein and hemisqualane, which help support damaged hair, add moisture and reduce frizz, leaving hair feeling softer and smoother. It’s a good option for hair that’s been put through heat, colour or regular styling, but the premium price means it’s definitely more of an investment than your average shampoo and conditioner.
