Our Take
A lightweight rinse-out conditioner formulated without film-forming silicones or waxes — a deliberate choice to avoid the buildup that blocks the K18PEPTIDE™ from working on mask days. The formula contains a biotech-produced polysaccharide and a ceramide blend that form a biomimetic shield against UV rays, environmental pollution, and mechanical styling damage for up to three days. K18PEPTIDE™ replenishes protein lost during washing. Clinically shown: 94% of users agreed their hair did not feel weighed down. Use this on non-mask wash days as your everyday conditioner, or after the mask once the four-minute processing is complete for extra softness and detangling. CGM-approved — no sulphates, silicones, parabens, or drying alcohols.

How to Use
After shampooing, squeeze out excess water. Apply a small amount from mid-lengths to ends — less than you would with a traditional conditioner, as this formula is concentrated. Leave for 1–2 minutes, then rinse. Use on non-mask wash days, or after the K18 mask once the 4-minute processing is complete.
