Our hair massager is made of soft silicone. It is softer and has a more suitable weight than the plastic one. Whether your hair is long or short, thick or thin, wet or dry, the Scalp Massager Shampoo Brush always easily goes through your hair and gently massage your scalp. The medium hardness silicone bristle does it all without hurting the scalp, and you won't have to worry about the sensitive scalp. It works great on dogs and cats too! 100%,We have our own factory and we have good confidence in the quality of our products.
