Jessica Chastain channeled old Hollywood glam with her Veronica Lake inspired waves. "Sexy Hair was excited Chastain’s stylist, Michele Talon, prepped her hair with Big Sexy Hair Volumizing Dry Shampoo to create a clean palette," says Sexy Hair stylist Marc Mapile. Here, Mapile offers us his suggestions on how to re-create Chastain's sexy look:

TRY IT:

STEP 1: Create a deep side part.

STEP 2: Set hair away from roots, to get minimal lift with plenty of curls on the midshaft through the ends, using 3/4 to 1-inch hot rollers using Healthy Sexy Soy Touchable. Allow to cool.

STEP 3: Comb out the set using a Mason Pearson brush and mold into place using Big Sexy Hair Spray and Play.

STEP 4: Finish with Straight Sexy Hair Smooth and Seal for frizz free shine.
