BeautyFeatures Style Guide:
- DO use a clarifying shampoo if you’re a heavy product or dry shampoo user to remove buildup and help our peptide penetrate and get where it needs to go.
- DO wait the full 4 minutes before styling or applying other product
- DO use every 4-6 shampoos consecutively to see and feel ongoing results
- DON’T condition your hair before application (trust us, most won’t need it after K18, if you still need, add a leave-in after the 4-minute window is up post-application)
- DON’T overuse, a little goes a long way.
- DON’T rinse out. This is a leave-in, so you know, leave it in!

Makes hair so soft perfect size for trying it out less breakage
-
Reduced breakage
Reduced breakage and I noticed an improvement after 3 uses. I bought the 15ml size bottle to try it out first and a small bit goes a long way. I would recommend for anyone who has damaged hair from colouring.

I can't recommend k18 enough.
I can't recommend k18 enough. This stuff is literally liquid gold!. I'm on my 3rd use so far and there's such a difference in my hair already. Less breakage and super soft. I love it and will definitely repurchase after I've used my 150ml size.

I was unsure about this
I was unsure about this product due to price but this was the perfect size to try it out. Left hair soft and in great condition even after 1 use. Can't wait to see it after the recommended 6 uses.

I have bleach blond hair and K18 is amazing. Really quick and easy to use and really works

A little goes a long way
After hearing great things about this and being recommended by my hairdresser, I decided to buy 2 of the sample sizes before committing to the full size. My hair is dyed blonde with some breakage at the ends so I was hoping this would help. I’ve been using it the last few washed as directed and I’ve seen a slight improvement. My hair definitely looks brighter and smoother. I’m unsure if it’s doing anything for my hair health but it’s still early days. I have shoulder length, fine hair and I got 4 washes out of the sample size for reference
