Lightly place the brush against your scalp and use moderate pressure. Hold the side opposite the protruding part in your palm and use gentle, short, and inconspicuous movements. When changing the position of the brush, move it slightly away from your scalp. <Caution> *Do not press too hard or move it widely. Also, do not move the brush while it is attached to your scalp. This can damage your scalp and cause hair tangles. ~When using as a shampoo brush~ Lather shampoo well before use. Lightly place the protruding part against your scalp and move the brush in small, gentle movements, following the direction of your hair's growth. <Caution> Do not use when rinsing, as the brush may not glide smoothly and cause hair tangles. Recommended Usage: 1. Move the brush from above your ears along the hairline toward the center of your face in small, short movements. 2. Move it in a zigzag motion from the hairline toward the top of your head, including along your face and nape. 3. Move it in a circular motion along the base of your ears. When using for scalp massage: Lightly apply to the areas of your scalp that are bothering you and move in a rocking motion. When you want to give your scalp a pleasant stimulation: Lightly tap the entire scalp. <Care Instructions> After use, to prevent deformation, deterioration, or mold growth, rinse thoroughly and dry off any cosmetics (shampoo, etc.) that may have been on the product, and store in a clean, well-ventilated area.
