Before: Liz Carroll, 32  

Liz, a Ph.D. student in psychology, says her hair is just too much of a good thing: “It’s really thick, and so it takes half an hour to blow-dry or else it looks like a triangle—poufy at the bottom and flat on top.” Besides wanting her hair to be less time-consuming, Liz hopes for a style upgrade, too: “I’m going to be starting my career [as a therapist], so I want a professional look that’s also warm and friendly and appropriate for my job.”
