Pros: color shows on dark hair, great price, does not rub on clothing
Cons: little messy when applying

"This product is great on dark hair. My hair was dyed black a few weeks ago and i spray on the color and it shows perfectly! (I bought Rock on Blue)I use it to create streaks in my bangs. I spray it on then hairspray it to last longer then before brushing it i quickly blow dry it. It looks really nice and stays in the hair for about two days if you don't wash it. It just fades. It doesn't rub onto anything and leave marks, either. When spraying it on use a towel to cover your skin since the spray comes out strong and will get on your hands if your holding pieces of your hair. It washes out in a breeze, you don't even need soap."
