Our Smart Scalp Massager features 4 synchronized grasping arms and 88 massage nodes that simulate gentle hand kneading, promoting blood circulation and rejuvenating every hair follicle. Say goodbye to dull, lifeless hair and hello to a healthier scalp. With 3 adjustable speeds, our massager offers a range of options to suit your needs. Use the slow speed for daily maintenance, the medium speed to relieve fatigue, and the fast speed for a soothing and calming effect. It's like having your own personal masseuse at the touch of a button. With IPX-7 waterproof rating, the electric head massager can be used for deep scalp massage and facial cleansing even while taking a shower. The soft, detachable silicone heads prevent hair from being pulled or tangled and do not hurt your skin or cause skin allergy.
