iv bought a similar product in green last year and thought it was really fun. I used it for halloween. so when i seen this blue colored hair wax i jumped on it. Well my teen son was home bored when it arrived so he wanted to try it. He has darker brown hair so i thought this be a good test too. He loved it and surprised how well it showed up. we dampened his hair which is perm treated. tussled it round in hair and let air dried. It did tranfer color while wet but the color was good and I know we could have done some fun styles with it too. It washed out without a problem
