K18 Leave-In Repair Hair Mask is a bioactive peptide treatment that works at a molecular level to reverse damage caused by chemical services, thermal styling, and mechanical stress. By reconnecting broken keratin chains, it helps restore strength, elasticity, and resilience from within.

This lightweight leave-in formula provides moisturising benefits that detangle, smooth, and soften the hair without weighing it down — making it suitable for all hair types, including fine or fragile hair. It delivers long-lasting repair that does not wash away with shampoo.

For best results, use during the first 4–6 consecutive washes after a chemical service, then continue every 3–4 washes to maintain hair strength and overall hair health. Refer to the dosage chart for correct application amounts.
