Title: Does not work well on black hair.
Review: I even left this product in for 35 minutes and it only slightly lightened my dark hair. I was hesitant to use it because of the health hazards and the dryness I felt in the sample lock of hair I dyed; had it not been a gift, I would not have used it (did it for courtesy). The conditioner is wonderful, my hair feels great--but the color doesn't come close to measuring up to the model's hair.
