Shampoo Brush, Pet Brush, Scalp Massage Brush Massages the scalp with 130 protrusions. Excellent foaming. Made of FDA-certified silicone material for semi-permanent use. You can sterilize it with boiling water to eliminate mold and bacteria, so you can always use it cleanly. Furthermore, it has an easy-to-grip shape. It is designed to be tangle-resistant for hair. It also has a shape that is easy for children to hold, so it is a product that we would like children who cannot wash their hair properly to use.
