○ Enjoy a head spa experience anytime at home Aiming to replicate the techniques of an esthetician, we developed the "twist kneading" movement that continuously pinches and lifts the scalp. With the three-dimensional electric rolling, which is particular about the inclination angle and rotation direction of the rollers, we aim to pinch and lift the hard-to-move scalp, awakening the beauty of the hair, skin, and expression from the scalp. ○ Professional techniques with Quattro 3D rollers Aiming to replicate the movements of the professional technique "thumb rotation kneading method," we developed our unique Quattro 3D rollers. The "15-degree inclination that enables three-dimensional 3D movement" and "reverse rotation at the top and bottom, with the bottom two rotating counterclockwise and the top two rotating clockwise" realize twist kneading that continuously pinches and flows in four places. ○ Waterproof structure that can be used in the bath* We adopted a round handle that fits perfectly in the palm of your hand and is easy to hold and move. Also, it has a waterproof structure* that can be used in the bathroom, so you can use it in the bathtub or while shampooing. ○ Two brushes and two modes It comes with two brushes: a kneading brush specialized for pinching and lifting the scalp, and a cleansing brush that pinches and lifts while cleaning. In addition, it is equipped with two modes: a HIGH mode for powerful stimulation and a LOW mode for a comfortable stimulation. *Body: Compliant with JIS waterproof protection grade IPX7 The body is waterproof, so there is no problem even if it gets wet.
