What it is
Approaching dirt with the power of electrons: The unique "Ion Wash Technology"* reacts to water and light, generating negative electrons that target dirt stuck in pores. *Patented technology combining TiO2 and solar cells applied to hair brushes. Scrape out dirt with two types of pins: The uniquely arranged two types of pins gently stimulate the scalp, helping to create a refreshing feeling. Revisiting frizzy hair from the roots, this gentle scalp care product does not damage hair.
Ingredients
How to use
Wet your hair thoroughly, lather the shampoo in your palms, and then gently comb your hair with a brush, massaging your scalp. At the end of the wash, comb your hair from the roots to the ends to make it easier to rinse off the foam.

Will I pay customs or import fees?
US orders: No. As of July 1, 2026, all US orders ship DDP (duties delivered prepaid), meaning we prepay all import duties on our end. Nothing is due at your door.

We're working on rolling out prepaid duties for more countries soon.
