THE LOOK Retro curled bob HOW-TO Harry Josh, of L.A.’s Serge Normant at John Frieda Salon says to apply volumizing mousse to freshly washed damp hair. Then blow-dry using a round brush; when done, roll sections of hair in Velcro rollers and let set while you do makeup. Take them out and lightly brush the hair; finish with a quick touch of Frizz-Ease Thermal Serum on the ends. INSIDER TRICK “To get this cut, ask your stylist for a one-length bob cut right below the chin,” says Josh. BUY ONLINE NOW John Frieda Frizz-Ease Thermal Serum, $9; folica.com.
