In our teens and twenties, most of us gamely embraced new trends, feathering, then bobbing, then shagging our hair—and seesawing from frosty pink lipstick (80s pop) to matte brown lipcolor (90s grunge). It made us feel pretty, current, and allowed us to play around with different personas. But somewhere along the way, many settled into “what works best for us," adopting a haircut we’ve more or less maintained ever since, choosing an everyday, goof-proof lipcolor (pinky nude for me), selecting a grownup signature scent…and letting Millennials have all the fun with hair and makeup. I think this is a mistake.
