Scalp Brush Kenzan — Hard

Kenzan is a reusable scalp brush with a butterfly outline and projecting rounded points. This black version is labelled Hard; Soft, Medium and Barikata are separate options. It can be used while shampooing or as a dry massage tool. The official instructions begin with wetting and lathering the hair, then moving the brush vertically around the ears and neckline. Its appeal is mechanical and tactile: a small object that changes how the hand moves, without an electronic component or a cosmetic formula.
