My hair is pretty healthy so I haven't really used it to "repair" any damage or anything. Can't speak too much on that, but what I can speak on is how it's the best detangler I've ever used in my life!!! My hair is natural, with a kinky-curly pattern. After shampooing my hair, I put this stuff on and work it through. Almost instantly, my my hair detangles and it's unbelievably easy to comb through. That says a lot because my hair is incredibly thick, and no other mask or conditioner has ever made my hair as easy to deranged as this stuff. If your hair is super thick and/or you haven't deranged it in a while, I recommend this. Extremely pricey for not a lot of product, but it's just that good that I don't care.
