Hair highlights tips!!!?

rich caramel and honey. I did a DIY kit and did peacan? it looks awesome, but heres a tip: get it done professionally, if not $ then trust someone to do it for you, and understand, i left it in for 15 mins, and i had bright blonde but after toner it resulted in a nice peacany goldeny tone, the box recommended 30-50 min >.> GOOD LUCK>
