AirWash is a non-aerosol, liquid dry shampoo built around K18's odorBIND™ biotechnology, which is designed to recognize and capture odor-causing sweat and oil molecules rather than simply masking them with fragrance. Translucent, porous microbeads absorb excess oil without the starchy buildup or white cast typical of powder-based dry shampoos.
Biotech-derived Mediterranean microalgae (Tetraselmis Suecica Extract) is included to help balance the scalp and manage excess oil production over time, while Arginine and Sodium Hyaluronate condition the hair and support hydration.
The formula is designed to work on all hair types, with closer application recommended for coily textures.
