K18 Molecular Repair Mask – Powerful Treatment for Damaged Hair Professional Strength for Damaged, Stressed Hair

Restore your hair’s strength, elasticity and shine with the K18 Leave-In Molecular Repair Hair Mask – a high-performance, salon-grade treatment designed to reverse damage from bleach, colour, chemical services and heat styling in just 4 minutes. This lightweight, leave-in formula utilises the patented K18PEPTIDE™ to reconnect broken polypeptide chains and disulfide bonds deep within the hair shaft, delivering smoother, stronger, hydrated hair without weighing it down. Suitable for all hair types, it’s the smart solution for colour-treated, heat-exposed or chemically-processed hair in need of true repair.

Hair that feels like new.
This lightweight leave-in mask repairs and fortifies hair while providing moisture to detangle, soften, and smooth—without any heaviness. For optimal results, use every 4-6 washes after a chemical service.

How to Use:

1. Shampoo (skip conditioner) and towel-dry hair until damp.
2. Apply 1 pump of K18 Mask (add more as needed for length and thickness).
3. Work evenly through hair, from ends to roots.
4. Leave on for 4 minutes—no rinsing required.
5. Style as usual.
