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.

Love
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.

Worked very well
An excellent addition to routine for damaged hair. A little goes a long way and you do not use every wash.

The only hair product you need
Transforms your hair! I could throw away all my other hair care products and only use this. Great to use when I’m in a hurry too as it saves waiting 10 minutes using a hair mask in the shower.
