A shampoo massager is a brush with bristles that can be used for gently massaging the scalp after applying shampoo to soaked hair. Use this brush gently all over the scalp to spread the lather, cleanse the scalp by exfoliating dead skin and product build-up. Massaging scalp using this shampoo massager is a great way to relax scalp muscles. Those who experience stress in their scalp will really experience the difference. It will also stimulate blood circulation and strengthen hair follicles. Cleaning this massage is simple; it can be washed under running water.
