Review title is Stayed in blonde hair WAY longer than instructions indicated. [SEP] Did this in my older daughter's hair in a peekaboo style. Used bleach to lighten her dark hair first. Turned out great. Put a couple little streaks in her little sister's blonde hair too... My dark haired girl has no pink left (Sept to Dec) but my blonde girl still has obvious streaks. The color was fun, and not too hard to apply -- took about 90 minutes including bleach time on dark hair. Wish it would wash out of my preschooler's hair!
