- Lift roots for big volume. For full body volume and lift, Moroccanoil® Root Boost creates a strong texture at the roots before styling with heat. Infused with antioxidant-rich argan oil, this root lifter adds volume to medium to fine hair for long-lasting texture, body and movement. Our high-performance formula helps control static and provides a natural-looking finish. Shake can well. Spray Moroccanoil® Root Boost generously on towel-dried hair at the roots. Using a round brush, blow-dry in sections, lifting hair away from the scalp. TIP: For enhanced body and movement, use Moroccanoil Volumizing Mousse along with Moroccanoil Root Boost prior to blow-drying and styling.
