K18 Biomimetic Hairscience Leave-In Molecular Repair Hair Mask (5ml) is a leave-in molecular repair hair mask which reverses damage caused by colour and bleach, chemical processing, heat, and mechanical styling. Formulated using bio-active peptide, this treatment increases overall strength and improves elasticity in all hair types, resulting in reduced breakage, split ends, and colour fade.

The mask has a lightweight, moisturising effect which detangles and keeps the hair smooth and soft without weighing it down. For best results, use for the first 4-6 consecutive washes following a service, and then every 3-4 washes as needed to maintain hair strength. Cruelty-free & vegan-friendly.

Directions of use:

• Shampoo hair but DO NOT condition on the day of using K18.
• Towel dry thoroughly.
• Begin with 1 pump of K18 Repair Mask and add more as needed depending on the length, thickness, and condition of the hair.
• Work evenly into the hair, one pump at a time, from ends to roots.
• Leave for 4 minutes to activate.
• Do NOT rinse out.
• Style as usual.
