I wanted the stylist to color all off my hair blonde but he only gave me highlights and I am really unhappy with it. Is there a way for me to go back and him to color the brown hair, that was my original hair color, with the blonde? Or will it mess up the already dyed blonde? Please help

He didn't hear you say, "all of my hair." Go back and tell him that he misheard you. Tell him that the highlights are OK, but you wanted blonde hair. Ask him to fix it.
