LookFantastic has slashed the price of an Olaplex treatment that shoppers say has given them great results. Originally £39, the Olaplex Rich Hydrating Mask is now £31.20 - it drops to £30.42 with the code FLASH22 . You can also get the mask for £31.20 at Beauty Bay, £39 at Sephora, and £39 at Cult Beauty. At LookFantastic, the mask comes in two variants: for rich, medium-thick hair, and for weightless, fine-medium hair.

The mask is designed to nourish hair from root to tip. It's formulated with Behentrimonium Chloride, which helps to hydrate the hair for enhanced manageability, glycerin, which helps hair retain moisture, and Bis-Aminopropyl Diglycol Dimaleate, which helps smooth damaged-looking hair.

Alternatively, you can try the K18 Biomimetic Hairscience Leave-in Molecular Repair Hair Mask, which is £30 at Cult Beauty. The leave-in treatment is designed to help with damage caused by bleach, colour, heat styling, chemicals, and more.

The mask is designed to nourish hair from root to tip. It's formulated with Behentrimonium Chloride, which helps to hydrate the hair for enhanced manageability, glycerin, which helps hair retain moisture, and Bis-Aminopropyl Diglycol Dimaleate, which helps smooth damaged-looking hair.

On the cheaper side, there's the Pantene Pro-V Repair & Protect Keratin Protect Hair Mask for £3 at Boots. It's meant to repair six months of damage in one use.

Back at LookFantastic, the Olaplex mask has 4.7 stars from 437 reviews. One person said: I bought this along with the Olaplex No. 6 leave-in treatment, and these products have completely changed my hair from being dull, damaged and frizzy to really smooth and manageable.

"Highly rate! I never leave reviews but felt I couldn’t not for this one. Will absolutely buy again, however I have only used products together so can’t say if it’s the combo or one of the products separately."

Another wrote: "Good for dry hair - been using every other wash and hair is already feeling much more hydrated and silky. Also smells gorgeous!"

"Really helped my dry hair," a third said. "I’ve tried so many other brands. Amina, k18, oribe. Nothing has hydrated my bleached frizzy hair like this product."

Of course, the mask didn't work for everyone. One disappointed customer wrote: "Not the best, left my hair dry and frizzy. Doesn’t feel too bad to touch but hair looks dull, frizzy and it doesn’t show the amount of effort I put into styling my hair today. Won’t buy again, I have only used it once but probably won’t try it again. In the conditioner graveyard or passed on."

But another happy shopper added: "Works very well to treat my coloured porous hair. My hair was soft and shiny after using."

You can buy the Olaplex Rich Hydrating Mask from LookFantastic, Beauty Bay, Sephora, and Cult Beauty. Get the K18 Biomimetic Hairscience Leave-in Molecular Repair Hair Mask from Cult Beauty and the Pantene Pro-V Repair & Protect Keratin Protect Hair Mask from Boots.
