This leave-in mask is designed for people with damaged hair from bleaching, coloring, or heat styling who want to restore strength and softness without weighing their hair down. It uses K18PEPTIDE technology to work at the molecular level on broken keratin chains, delivering immediate smoothness and bounce. The 5ml size makes it easy to try or travel with.

K18PEPTIDE — Proprietary bioactive peptide that mimics the natural keratin structure of hair, penetrating deep into the cortex to reconnect broken polypeptide chains and restore strength, elasticity, and softness from within.

Amodimethicone — A lightweight silicone derivative that provides smoothing and frizz control without weighing hair down, enhancing manageability and shine.

Isopropyl Alcohol — Helps deliver the K18PEPTIDE deeper into the hair shaft by temporarily opening the cuticle layer for maximum ingredient penetration.

Citric Acid — pH adjuster that optimizes formula acidity to minimize cuticle swelling, seal the hair surface after treatment, and improve smoothness and color retention.

The K18 Leave-In Molecular Repair Hair Mask is a clinically proven, science-backed treatment that works at the molecular level to reconnect broken keratin chains inside the hair cortex. Powered by exclusive K18PEPTIDE technology, this weightless leave-in formula delivers immediate and lasting results including softness, smoothness, strength, and bounce after just one use.

Unlike traditional conditioning masks, K18 does not coat the hair surface. Instead, it penetrates deep into the cortex to repair damage caused by bleach, color treatments, chemical services, heat styling, and mechanical manipulation. Its pH-optimized formula minimizes cuticle swelling and supports long-term hair resilience with every application.

Suitable for all hair types and textures, the K18 mask is vegan, cruelty-free, and color-safe making it a universal solution for anyone experiencing dryness, breakage, or chemical stress. Apply after shampooing on damp hair, leave on for 4 minutes, and style as usual without rinsing.
