Amazing product! Transformed my hair

5 stars out of a maximum of 5

Honestly didn’t think this product would be so worth the hype but it really is. I had a lot of breakage on my hair due to stress, diet changes, etc as well as constant heat and I used this product once and it really helped! I’ve finished my first bottle and definitely going to repurchase!

Worth the hype

5 stars out of a maximum of 5

The best hair product on the market. Sad it’s gone up so much in price but it’s still worth it to me. Has helped my hair grow so much as it’s not as prone to breakage

Holy Grail!!

I spent a lot of time researching this purely because it’s so expensive and decided to try the smaller size and I’m so happy with the results. It’s made me coarse thick hair soft and frizz free. I’ll definitely be buying the bigger one next

I love this mask! So easy to use and saw such an improvement in hair condition since using it! Just be sure when you use that you rub in between your hands until it goes like a white cast!

Felt this really worked

5 stars out of a maximum of 5

Had the smallest size to try and felt it made such a difference to my hair. Less frizz, more shine and ends visibly better after 2 or 3 applications. Only need to use the smallest amount so although it’s pricey I will be repurchasing.

Lush!

I wish I didn't like this because it's very expensive! It's worth it though for the shiny, silky hair without having to condition in the shower!

Was recommended by my hairdresser. It's really improving the condition of my hair, along with the shampoo.

Wow!

This is a miracle product. I decided to buy this based on reviews and I wasn’t disappointed. It leaves my hair super silky, straight and glossy without a hint of frizz in sight. I’m excited to continue using this and seeing more positive results over time.
