Jessica AlbaTHE LOOK Long sleek layers HOW-TO "To get this kind of movement, you want your stylist to cut long layers that start just below the chin," says stylist Michael St. Germain. You want to ask for concave layers, which are more smooth than choppy layers. To style, add an anti-frizz product to your hair as well as something to add body, like thickening spray. Blow-dry straight and finish with a one-inch flat iron (St. Germain recommends the Chi). INSIDER TRICK If you have thick, coarse hair, finish with smoothing serum.
