This stuff really turns your hair bright pink, and even though its kind of splotchy, it looks great. You must spray this stuff in a well ventilated area. It doesn't say to do that on the bottle, so the first time I used it, I sprayed it on my hair inside my house and ended up coughing pink goo. It was scary! Use this stuff outside.
