THE LOOK Straight diagonally-parted bob

HOW-TO “Ask your hairstylist for a wedgy bob full of texture,” says stylist Jerome Lordet of N.Y.C.’s Pierre Michel salon. Get this sleek style by running a flat iron through one-inch sections of hair and finishing with smoothing serum on the ends to keep them smooth.

INSIDER TRICK The front pieces should be chin-length and the back should have layers cut into it. “You get the wedge by layering the hair from shorter to longer at the nape of the neck,” says Lordet.
