It works

I've been using this for a few weeks now and I can definitely see the difference in my hair. A bit over priced in my opinion but for anyone desperate to revive their hair its worth a try

Wonderful product!

Superb Product, worked very well on the health of my heavily bleached hair. It’s expensive, but worth it. A game changer!
