Amazing stuff!!

5 stars out of a maximum of 5

Absolutely love this! I have very fine, thin hair with heat and bleach damage and this stuff appears to be working miracles! Make sure to use it as directed though - don't condition your hair in the shower before hand, and use just a very small amount (it really does go a lot further than you think!) I also make sure i only run my hands through the lengths with it so as not to make my roots oily. Leaves my hair much shinier, smoother and somehow it also seems to have much more bounce/body! Very happy (apart from the price!)

The best hair mask

5 stars out of a maximum of 5

This has saved my hair, effects can take a little while to show but last longer than other similar masks.

Worth it if your hair is dyed

5 stars out of a maximum of 5

I have hair down to lower back which I stupidly got balayage in, blonde, for the first time ever about 2 years ago. Ever since then didn’t matter how much I trimmed, what masks I used on my hair. Nothing stopped the split ends and dryness. My hair turned into the most unmanageable hair ever.  Then I saw this on a hairdressing video and thought I’d give it a shot. I’ve used it for past.. 6-8 weeks I’d say. Completely changed my hair. It’s back how it used to be. No split ends, I can brush it without it being super tangly. Honestly completely a game changer.  It says to use it 4-6 washes then every so often but I use it after every wash. It’s just amazing.  Bottle looks really small but I use maybe a pump and a half. Like I say my hair is lower back length and very straight and not super thick but about medium thickness. So don’t have to use much. Will 100% repurchase

You can follow with conditioner!!

This is an excellent, innovative bond repair treatment. Given time it will transform chemically damaged hair! The instructions say to just leave the product in after waiting several minutes, but the brand has made clear many times now that it’s fine to rinse and condition afterwards - so don’t forget!

It really works!

5 stars out of a maximum of 5

I was sceptical, the price is so high for so small hair product, but it actually works!  You don’t need to use a lot of product, definitely start with one pump and add when needed - I didn’t trust the label at first but it’s true! I have armpit length hair and I use 2-3 pumps no more.  Hair felt nicer, softer and have more shine to them immediately.

So far so good

4 stars out of a maximum of 5

Used once to twice a week and so far so good. Nothing drastic to report but hair does feel slightly smoother.
