My hairdresser used this on me when my hair was at its worst, and it became super shiny and looked healthy. Since then, I've used it a couple of times on special occasions and have always been satisfied. I think it works best if I comb or brush my hair with the mask in before rinsing. It's a bit pricey, but it usually lasts for two uses for me even though I have thick and long hair. I gave one as a gift to a friend who has curlier and frizzy hair, and it worked great for her too.
