Not for me
I really wanted to like this but I honestly cannot see any difference in my hair,I used it on damp hair,no conditioner,rubbing the product between my hands before-the whole shebbang.Not for me I guess,if anything my hair looks a bit matte and brittle after using and noticed a lot more shedding so I stopped using after the 4th attempt.

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
