“Britney has wanted a change for about a month, but we waited a while until we decided to go with it,” Brit‘s colorist Brittany Hunter from Mark Slicker Salon tells E!. “We wanted to make sure she was going to be committed to it before we made the change as it can be a difficult process going from light blonde to brunette. We started the process on Thursday and then finished it up on Sunday. We wanted to make sure the color was going to stick and it wasn’t going to fade.”
