This mask has been developed in collaboration with Chris Appleton, stylist to the stars (including Kim Kardashian). And it was a real hit with our testers. Chris knows what he’s doing when it comes to styling hair, and restoring life to damaged ends. All those hair colour changes for Kim and her sisters aren’t going to repair themselves, after all.

Color Wow, already famed for its smoothing spray and frizz-softening formulations, developed this mask to add silky shine to straight hair, while defining and softening a head of curls. But did it deliver?

It made lengths easier to comb through and was simple to use, with much of the feedback focused on how “super shiny and silky” it left strands.

Our panel found this great value mask intensely hydrating. Not only did it quench thirsty strands, but it also left most testers with healthier-looking hair and beautifully shiny tresses.

It didn't do much in the way of minimising breakage or dandruff or boosting colour vibrancy, but for its affordable price and heavenly smell, it’s a total bargain buy.

Aside from booking in for a trim, there's not usually much you can do to banish split ends. But this mask managed to do the impossible, with most noticing fewer split ends after the trial period. Formulated with renewable and sustainably sourced ingredients, the mask left all our testers with smoother, more hydrated strands. It calmed frizz, too.

Some did describe the packaging as "basic", but it’s a small compromise when you consider it’s made from 100% clean energy, with zero environmental impact.

Originally designed to revive Audrey Hepburn’s iconic locks after long days of filming, this cult classic has become a staple for celebs, including A-listers like Kate Winslet and Cate Blanchett. Apply to ends as a pre-shampoo treatment for a minimum of three minutes (for a deeper condition, leave on for 20) and prepare to be amazed.

Our testers appreciated that it didn’t leave their hair feeling greasy or heavy, instead making tresses softer after just one use. One tester even found their natural curls appeared bouncier and more defined. Our panel did prefer the pump dispenser over the tub, however (less mess).

Score: 81/100

This vegan formula is designed to leave fine hair looking plumped and glossy after styling, and all for a bargain price. Did it really work? The answer is... yes.

One tester described the smell as “delicious” and it left our panel with intensely hydrated strands. It delivered on smoothness too, with most agreeing it left them with a silky finish.

Although some would have preferred a squeezable container and it didn’t boost colour for many, it's excellent value for money given how much you get in the tub.

Almost all our testers were impressed with how well it revitalised damaged tresses, with one noting its “plumping” effect. It’s not cheap – at £28 for 100ml, it’s one of the pricier masks on our list – and one tester did note that they needed to use a lot to cover their hair.
