K18 Leave-In Repair Hair Mask 5ml

K18 Leave-In Repair Hair Mask is a powerful 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 strength, elasticity, and resilience from the inside out.

This lightweight leave-in formula delivers moisturising benefits that detangle and smooth the hair without weighing it down, leaving it soft, supple, and manageable. Ideal for all hair types, it provides long-lasting repair that doesn’t wash away.

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