Sleep-In Rollers Backcombing Brush - another tool to aid big hair.
Determine what part of your hair needs volume and grasp a small section of hair in your hand. Hold the hair straight upward and pull it tightly enough so that none of the strands can escape.
Pull the lock of hair you are holding forward toward your face, at an approximate 45-degree angle. Place your brush about halfway between your hair's roots and your hand, and apply firm brush strokes downward toward the scalp.
Repeat this motion until there is a cushion of hair at the base of the hair section. Use your hairspray to help hold the back combing.
