Love this!! My hairs always so much softer and less frizzy when I use this! It’s quite expensive tho otherwise I’d give it 5 stars

It really works

5 stars out of a maximum of 5

I did not expect it to work so good. I feel the difference after only 2 washes. I did not think my hair needed this, but I was wrong. My hair feels so nice, I feel how much smoother it feels. Hope it works long-term just as good.

Amazing but expensive

4 stars out of a maximum of 5

Amazing product - expensive but you only need a small amount and really does leave hair conditioned and easy to style. Be careful not to use too much - it's definitely not like putting on conditioner. Early says so not sure what the long term results will be but so far so good. The best product from the range so if you have fine/dry hair and have tried everything give this a go.

Excellent

5 stars out of a maximum of 5

I damaged my hair roots with chemical straightening so have been trying different masks. I received this in the 2023 Sephora calendar and am really taken aback by how effective it is. The application is odd, you don't apply conditioner beforehand (although I did still apply it to the ends as I mostly applied the mask to my roots where the damage was). However it worked a treat, my damaged hair was softer after the first application. Despite the high price, I will probably purchase the 50ml size.
