K18 Leave-In Molecular Hair Mask – 15ml

The K18 Leave-In Molecular Hair Mask (15ml) is a breakthrough, science-backed treatment designed to restore hair health from the inside out. Powered by the patented K18Peptide™ technology, it works at the molecular level to reconnect broken keratin chains deep within the hair cortex — reversing years of damage caused by bleach, color, chemical services, and heat styling in as little as 4 minutes.

Unlike traditional masks that coat the surface, K18 penetrates into the cortex for true repair, not just the appearance of it. No rinsing required. Simply apply to clean, damp hair and style as usual.

What Makes It Different

The K18Peptide™ is a bioidentical peptide that mimics the natural polypeptide chains found in hair. This allows it to actively reverse structural damage rather than temporarily masking it, delivering measurable, cumulative results with every application.

Key Results

Up to 91% improvement in hair elasticity. Visibly stronger, softer, and smoother hair. Restores bounce and reduces breakage for all hair types including color-treated, bleached, and chemically processed hair.

How to Use

After shampooing and conditioning, squeeze out excess water. Apply a small amount to clean, damp hair from roots to ends. Do not rinse. Style as desired. Use once per week or as needed based on damage level.

Suitable For

All hair types. Especially effective for bleached, color-treated, heat-damaged, chemically processed, or over-styled hair.
