Spectacular, gimme 14 of them right now
This is my third bottle of it. I first tried it to get my hair in better shape before my wedding, but I might just keep buying it, even if it's pricey. My hair is fine and grows really slowly, and never got longer than shoulder length previously due to breakage and having to cut more to even it out, but it's definitely the longest it's ever been without looking scraggly and full of split ends. 10/10, no notes

Very disappointed
As a Sikh woman who doesn’t cut her hair, I was looking for something that would help with split ends and help manage frizziness. This product made my hair incredibly dry and brittle. Would not purchase again.
