Our Take
A sulphate-free shampoo built around Forbidden Black Rice Water — a traditional East Asian ingredient used for centuries to strengthen and grow hair. Combined with Biotin, Saw Palmetto, and Ceramide, all delivered via sub-micron technology for deeper penetration than standard formulas. Designed to promote hair growth, prevent hair loss, and fight breakage. Protein-containing — suitable for high-porosity, weak, or breakage-prone hair. Pairs with the Rice Water Conditioner for the full system.
