Okay I really need help, I'm just now starting out to do hair [went to school, got licence etc] well I have a client soon with 100% grey hair but she colors it herself let's say a level 7.. and now wants to add highlights throughout. well that was the middle of January and she is coming ln a few days.. what I would like to know is, will the bleach lift her hair evenly since it being a 7 is so light? I use blondor bleach btw.. Idk, I'm just really nervous. I don't want to mess up you know? Or do I need to strip the hair? I don't want to go through that long process if I don't have to.. and I know everyone's hair is different but just from experience has anyone dealt with this before??
