Say goodbye to unwanted hair color with COS (Color Out System)—the safest, most effective way to remove artificial colour without compromising hair health. In just 20 minutes, COS works by shrinking dye molecules so they can be easily rinsed from the hair, restoring it to its natural clarity.

Unlike harsh bleach or ammonia-based removers, COS’s gentle formula preserves the hair’s condition, making it perfect for immediate recolouring. No need to worry about hair levels—COS targets all artificial pigments, leaving the hair strong, soft, and ready for its next transformation.

For stubborn tones, pair with Color Shade Lifter (CSL) to lift remaining artificial colour.
