To use as a shampoo, apply evenly on wet scalp and hair, gently lather with fingertips without over-massaging, and rinse thoroughly. To use as a mask, apply to scalp and hair, leave on for 3-5 minutes, and rinse thoroughly. This product is dermatologically approved and provides a unique experience with its highly concentrated actives and addictive fragrance.
