There's just something about a trim, chop, or dye job that goes along with a big life transition.Got a new job? Invest in a new boss haircut. Celebrating a major birthday?

OK, maybe you're not a world-renowned recording artist who can relate to that last one, but Demi Lovato is. Amid hints of an upcoming album and rumors of a budding romance with former Bachelorette contestant Mike Johnson, the star is testing out a new hair color.
