I read other reviews and decided to try it, but not leave it on as long as the directions say to. I put the paste onto my hair, used the "shower cap" - then I shaved my legs. That was it; that was the amount of time I left it on my hair and it worked great. My hair is blonde to begin with and is very sensitive - I did not want it to turn orange like another reviewer. The 10 or so minutes that I left it on for made my hair the nice blonde shade of my youth, as if I'd spent weeks in the summer sun. The directions called for leaving it in for 30 - 45 minutes, I think that is why the other lady's hair turned orange - it works very quick and is strong. As it fades/washes out of my hair, I do plan to buy it again. Also, my hair is shoulder length and the package gave enough for two usages. Hope this helps anyone on the fence.
