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

This lightweight, leave-in formula moisturises and detangles while keeping the hair smooth, soft, and manageable — all without weighing it down. The results are long-lasting and do not wash away, making it ideal for maintaining healthier, stronger hair over time.

For optimal repair, use during the first 4–6 consecutive washes following a chemical or colour service, then continue using every 3–4 washes to maintain hair strength. Refer to the dosage chart for exact usage amounts.
