Worth the Investment
This has made such a difference to my hair. It feels stronger, looks shinier, and is much less prone to breakage after styling. I love that it's a leave-in treatment and doesn't add any heaviness. It's definitely become a staple in my haircare routine.

Bottle only lasts a few uses
I do love this and see a difference when I use it but I got through this soooo quickly I was shcoked. It says use 3 pumps but I have a lot of long, fine hair and I needed about 6 pumps to feel like it made a difference. Very disappointing it is so expensive for such little product
