K18 Leave-In Molecular Repair Hair Mask 50ml is a treatment that repairs hair damage at a molecular level in just four minutes. This leave-in mask benefits anyone experiencing damage from bleach, colour treatments, chemical services, heat styling, or mechanical stress. Clinical research demonstrates that hair is restored to 91% of its original strength and 94% of its original elasticity when used as directed.

Key Features

• Patented K18PEPTIDE™ Technology: Reconnects broken polypeptide chains in hair's core structure for molecular repair
• Four-Minute Application: Works quickly without rinsing to restore strength, softness, smoothness and bounce
• Vegan Formula: Free from parabens, sulphates and silicones whilst remaining pH-balanced at 5.0-6.0

How often should I use the K18 hair mask?

Use the treatment for 4-6 consecutive washes initially to build up repair, then apply every 3-4 washes as needed to maintain hair strength and health. The K18PEPTIDE™ doesn't wash away with shampoo, ensuring lasting results between applications.

Do I need to rinse out the K18 mask after application?

No, the mask is designed to be left in your hair without rinsing. After applying 1-3 pumps depending on your hair length and density, wait the full four minutes for activation, then style as usual.

Can I use conditioner with the K18 treatment?

You should shampoo your hair but skip conditioner before applying K18, as this allows the peptide to penetrate effectively into your hair strands. If you wish to use a conditioning treatment, you can apply it after the four-minute waiting period.

What types of hair damage does K18 address?

The treatment repairs damage from bleaching, colour services, chemical processing, heat styling tools and mechanical styling. It works by targeting broken polypeptide chains deep within the hair's structure, reducing breakage and split ends whilst improving elasticity.
