Before: Penny Chan, 35

“I’ve had this style for a decade,” confesses Penny, a scientist and mother of two boys, ages 6 and 2. Her styling routine consists of “washing and blow-drying for about two minutes. But it’s straight and has no volume, so it just falls flat.” Most of the time, she ends up tucking her hair behind her ears. She doesn’t have time for a lot of upkeep, but still “I want to look professional and young,” she says. “I just wish someone would tell me what will look good!”
