I stopped buying it for sometime- WOW

5 stars out of a maximum of 5

But WOW - my hair loves it. Stronger, softer, smoother and bouncier hair in 4 minutes.

Expensive but worthy

5 stars out of a maximum of 5

I like this treatment, you only need a tiny amount to make such a big difference to your hair. Only 2 washes in so yet to see the full effects. Very expensive for the size though.

Hair is definitely better

5 stars out of a maximum of 5

Hair got visibly better, it feels softer and looks shinier. I’ve been using it every other day for 2 weeks now and it definitely does something, is it worth the money? Not sure, but it does work.

Feels like it makes a real difference

4 stars out of a maximum of 5

Feel like this is haircare that actually does something. I definitely find my hair (coarse extremely damaged naturally wavy) easier to brush through and feels less damaged after using. Price is a lot but if its proven to work I think better to invest in than expensive products that may not work.

This is amazing for keeping ends soft and strong. Also seems to have reduced frizz all over

Used and reommended by my hairdresser!

5 stars out of a maximum of 5

I have balayage every 12 weeks and my hairdresser uses this product in salon as part of the process! Of course I had to purchase this for that reason as recommended by my hairdresser to maintain my hair out of salon also! 5*

Love it

5 stars out of a maximum of 5

Oddly I cannot stop using it. So I guess it does help my hair, pricey but definitely worth it!
