K18 Leave In Molecular Repair Hair Mask 50ml

K18 Leave In Molecular Repair Hair Mask 50ml is a lightweight leave-in hair treatment designed for hair affected by bleaching, colouring, chemical services, heat styling and regular brushing. Used after shampooing, it helps hair feel softer, look smoother and become easier to manage without adding a separate conditioner or rinse step. The streamlined application makes it particularly useful for colour-treated, dry-looking or fragile-feeling hair that needs consistent care after washing.

Powered by the patented K18Peptide™, the formula is designed to support hair that has been compromised by salon services and frequent styling. Its lightweight texture spreads through towel-dried hair without leaving a heavy or coated finish, helping it suit fine, thick, straight, wavy, curly and coily hair. The mask is also described by the brand as pH balanced between 5.0 and 6.0, colour-safe, vegan and cruelty-free.

Suitable for: All hair types, especially hair affected by bleach, colour, chemical treatments, heated tools or mechanical styling that feels rough, looks dry or has become more difficult to manage.

How to use:
