Is the K18 hair treatment right for my hair?
Whether your hair is fine or coarse, if it’s damaged, over-coloured and processed or just outright compromised, this treatment has your name on it. The thing to remember here is that this is a mask you don’t rinse out: if you think that’s likely to be too heavy for your hair, you’ll want to get the smaller size first and try it out.

How should I use the K18 leave in mask?
When it comes to this little miracle worker, you need to throw out your usual ideas about how to use a hair treatment. Here’s the correct order of operations:
First, wash your hair.
Then, towel it dry. You want it to be damp rather than dripping wet.
Now, it’s time to apply your K18 leave in mask. Start with one pump, and work it through your hair from root to tip.
If you have short or fine hair, that will be enough. It may even be too much. But if you have long, thick, very damaged hair, you’ll want another pump or two.
Wait four minutes. Do not rinse.
Now’s the time to apply any other products you usually get involved with. Style your hair however you’d like.

How does the K18 hair treatment work?
It repairs the keratin bonds in your hair. They may have been damaged by colouring, heat, or by physical styling (likely a combo of the three) but regardless, the K18 hair mask will repair those bonds.

K18 is made with a patented peptide which helps to repair the links between keratin cells, and because you don’t rinse it out, that effect continues after you’ve applied. We’re talking real, visible change, friends.

Troya Beauty is one of the only authorised retailers and stockists of the K18 hair treatment.
