So my hair is currently bleached blonde. For bleached hair it’s pretty healthy and it was done professionally. I want to go dark brown (or even black) for a bit though, but I know that at some point I’d want to go blonde again. How bad is the process from brown to blonde? I would get it done professionally but would it damage my hair / be super hard/bad? Is me going brown or black worth it?
