Restore your hair's youth and strength in just 4 minutes with the K18 Leave-In Molecular Repair Hair Mask. This breakthrough clinical treatment reverses damage from bleach, color, chemical services, and heat by using the patented K18Peptide™ to reconnect broken keratin chains at the molecular level.
Unlike traditional conditioners that only coat the surface, K18 works from the inside out to deliver permanent repair that won't wash away. Simply apply to damp hair after shampooing, wait 4 minutes, and style—no rinsing required.
Perfect for all hair types—straight, curly, coily, and everything in between—this lightweight mask restores strength, softness, smoothness, and bounce. The 0.5 oz travel-friendly size is ideal for testing results or maintaining your hair health on the go.
Vegan, color-safe, and cruelty-free with a pH balance of 5.0–6.0 to seal in the peptide and close the cuticle.
