Good hair is the thing that we all dream about. Silky smooth, glossy locks that don't tangle or break seems like an unreachable dream. According to some celebs (and a lot of TikTok), a hair mask that actually repairs and smooths hair has *finally* been found.

And, of course. It's the K18 Leave-in Molecular Repair Hair Mask.

If you haven't already heard of the gorg mask, you may have been hiding under a rock but you can breathe now because it's about to change your life. It's as easy as popping on when you get out of the shower, just before you style or blow dry. Yep, no rinsing out at all.

Not to mention all the celebs that have been caught red-handed (or tbh just announced that they love it) throughout the years. The list includes A-listers like Khloe Kardashian, Selena Gomez, and even Rihanna.

According to TikTok, you've got to warm up the product in your hand until it's a thick white paint colour and then massage it through your ends to really get the full benefit of the product. Oh, that's made with K18's peptide-patented ingredients too. Super fancy.

What makes it even better is that a bottle of the stuff is only £25, and it will be sure to last as you only need to use it on hair wash day. If you're not totally sold yet, you can try a 5ml bottle for under a tenner. Barg.

Tried and tested by A-listers Hailey Bieber, Selena Gomez and Khloe Kardashian, the K18 Molecular Repair Hair Mask is one to pick up for smooth locks.


  • Leave-in for ease
  • Quick and instant results
  • K18Peptide patented molecules
  • Full repair of damaged hair


  • May run out quickly if you get the smaller bottle

So, there we have it. It's affordable, easy to use and trusted by the celebs - clearly, the K18 Molecular Repair Hair Mask is exactly what we need to add to our haircare routine.

Check out which of the big celebs love it out there below, including celebs like Selena Gomez, Hailey Bieber and Rihanna.
