Our Take

K18's reinvention of dry shampoo, powered by patented ODORBIND™ biotech and biotech-derived Mediterranean microalgae (Tetraselmis Suecica). Unlike conventional aerosol dry shampoos that leave a visible white cast or starchy residue, this liquid formula uses translucent silica microbeads to absorb oil without buildup. Clinically shown to eliminate odour and reduce oil for up to three days after one use. Contains Alcohol Denat. as a carrier (classifying it cgm_modified), though in practice it evaporates on application. Non-aerosol, scalp-friendly, and does not disrupt existing curl styles. Concentrated — start with one spray per section. A worthwhile tool for curlies extending time between wash days.

How to Use

Shake well before use. Hold 15–20 cm from the roots and spray directly onto the scalp and roots. Massage in gently — the formula applies wet but dries clear with no white cast. Start with fewer sprays than you think you need. Use between wash days to absorb oil and eliminate odour for up to 3 days.
