My hair is half partial highlights and the bottom half is a dark brown. This new lady, I noticed, used the blue bleach for my Medium brown hair and now my roots are BLEACHED BLONDE while the rest of my hair is a nice Golden blonde.

I plan on going back so she can fix it but I'd like to hear some ideas on how it can be fixed [if even].

I can't get lo-lights because I purposely have the top half with ALOT of blonde highlights so it can contrast with the dark brown underneath.
