Osaji Cool Shampoo Ryo
A silicone-free shampoo that addresses the summer scalp environment, supporting a healthy scalp while washing away the heat. Formulated with cleansing agents that provide a refreshing feel while remaining gentle and low-irritant, it comfortably cleanses the scalp even during the season of increased sweat and sebum. Infused with adsorptive hyaluronic acid and betaine, it leaves a hydrated finish within its crisp, clean usability. Cooling ingredients such as camphor, menthol, and peppermint leaf oil deliver a lingering, refreshing chill.
