Reverse hair damage with the K18 Leave-in Molecular Repair Hair Mask, a leave-in treatment mask designed to restore the hair in just four minutes.

Bleach, colour treatment, chemical services and heat can all wreak havoc on the hair. Powered by the K18PEPTIDE™, this haircare treatment can help repair the damage. Giving both immediate and lasting results, it helps restore strength, smoothness, softness and bounce.

Working at the innermost layer of the hair, this vegan-friendly mask can even get to work on extreme damage. Boosting core strength and elasticity, it helps reduce split ends, breakage and colour fade. With lightweight moisturising benefits, it will not weigh down the strands as it helps prevent tangling for hair that looks and feels renewed.

Key Benefits

  • Counters damage from chemicals, bleach, colour and heat
  • No need to rinse
  • Reduces split ends, breakage and colour fade
  • Adds softness and bounce to the hair
  • Boosts strength and elasticity
  • Helps prevent tangles

A gamechanger

As someone that hates pre shampoo treatments because of the faff of having to wet my hair first, this has been revolutionary for me. I’ll never be without it! Cut my shower time in half whilst giving me the best results I’ve had from a product. Would recommend to anyone and have gifted it to countless people

Great

I received the smaller size as a free gift with k18 oil and I loved it so purchases the bigger size bottle. It’s made such a difference to my hair it feels so soft and much more manageable. My hair feels much stronger after using for a few months.This is definitely something I will continue to use in my hair care routine.

amazing for hair

I originally tried the smaller size from a previous advent calendar, then repurchased in the medium size as I didn't want to invest until I knew I really liked it. It is expensive but I do believe it does live up to its claims It feels slightly unusual to shampoo and not follow with conditioner but if anything my hair feels better. i look forward to trying more from the K18 range, I would highly recommend. I’ve also gotten my hairdresser to switch to K18
