K18 AirWash is a non-aerosol dry shampoo that features newly patented odorBIND smart-release biotechnology. It clinically eliminates odours, reduces oil, and keeps working for up to 3 days. The dry Shampoo is made with translucent porous microbeads that absorb excess oil without visible starchy buildup or white cast. The patented odorBIND smart-release biotechnology recognizes, traps and eliminates odour-causing sweat and oil molecules, and replaces odors with a subtle fragrance for a clean, fresh feel, for up to 3 days. The microalgae help balance the scalp and control excess oil production over time.
