Love it
After having extensions in and then having some bleach on my already very fine damaged hair. I found this really helps. It’s helps me get the comb through my tangled mess of hair and it feels lovely and soft and smooth afterwards. I have greasy hair and didn’t find this heavy or that it made my hair any greasier. Expensive for the size but if you’re careful with how much you use. It lasts longer than you think it would.

Lifesaver
I bought this after being recommended it by my hairdresser as my hair is quite thick and gets dry at the ends so is more prone to split ends. It's definitely helped reduce the damage, but it definitely takes time to work and isn't immediate. Paired with a good shampoo it's great (don't use conditioner with it or it won't work)

Great taster for the bigger size
Bought this because of the hype. There's actually a fair amount in the small size and has so far lasted me three hair washes. It made my hair softer and could feel the difference in health after my hair had fully dried

Not sure
I think I can live without this mask. I have used 50 ml, it lasted for a long time. But I can't see a great difference. I think the price is too expensive.

This product is fabulous, well worth the price tag. It makes my fine hair feel amazing without weighing it down or making it greasy. Will continue to repurchase.

Long dry curly hair
I have used this twice and the difference in my hair is amazing! So soft and shiny, normally after 2 days I have to refresh my curly hair but I hardly need to do anything after using this. Curls hold way better and feel more moisturised. I have used olaplex in the past but this is miles better!

Amazing
Great smell and is an amazing product, if you have dehydrated skin, I do not think that the product is for you, however, I liked it.
