Apply your favorite PHILIP B. shampoo, scalp scrub or oil onto the convex tips of the Scalp Massager. Gently press the tips to your scalp and massage in small circular motions using medium pressure. Avoid large circular motions to prevent tangling. Repeat all over the scalp for as long as you’d like. Rinse the massager in cool water and let dry after each use. Can be used on wet or dry hair, with or without product.
