Hi I was wondering if someone would help me, I am training to be a hairdressing I am in my second year at college but not very confident with choosing what to use when it comes to colour , my boyfriends sister in law has recently asked me to colour her hair, she said her usual hairdressing uses a mix of 9/0 and 10/0 but she wants to be lighter , would it be safe to use 10/0 koleston perfect with bleach highlights? And what peroxide should I use? Thanks
