Your Most Stylish Year Ever

"Post-summer hair revival should be all about treatments, treatments, treatments," says stylist Kattia Solano, founder of N.Y.C.'s Butterfly Studio. "I recommend buying a great hair mask, like Kerastase Masque Age Recharge. Apply it twice a week if your hair is parched from the summer sun."
