What it is
It feels great. And on top of that, it leaves your hair shiny and smooth. The difference is microcurrent. G-ZERO COIL MICROCURRENT ION SHAMPOO BRUSH - Developed based on the "G-ZERO COIL MICROCURRENT PRO," an ion shampoo brush from a salon that provides comfortable scalp care. The silicone body is infused with natural negative ion minerals (tourmaline, ceramic, etc.), and the design takes advantage of the material's properties. It is equipped with the unique "G-ZERO COIL" (8mm x 8 pieces) that generates a weak electric current (microcurrent) and negative ions with a unique winding method. It suppresses static electricity in the hair, making it easier to manage. In addition, the brush structure with microcurrents supports fine lathering. It gently washes away dirt from the scalp and pores while protecting the hair from friction. The silicone material is soft and elastic, and is designed not to damage the scalp or nails. The tip is made longer in anticipation of wear, and after wear it can be used as a massage brush. Recommended for brushing during shampooing and conditioning, it elevates your daily hair care routine. It also makes a perfect gift. Its convenient size makes it easy to carry on trips and business trips. This single product will give you salon-quality results every time you wash your hair.
