K18 Leave-In Molecular Repair Hair Mask is an intensive leave-in treatment developed for hair that has been damaged by bleach, colour, chemical services and heat.
 
Rather than being used like a traditional rinse-out conditioning mask, K18 is designed to remain in the hair after washing. Its molecular repair technology works within the hair to help address damage while improving strength, softness, elasticity and manageability.
 
The concentrated leave-in formula means only a small amount is required. It's particularly useful for those who bleach, highlight or frequently colour their hair and are looking for a more targeted repair treatment.
 
The 15 mL size is also a great way to introduce K18 into your routine before committing to the larger full-size product.
 
Best for: Bleached, highlighted, coloured, chemically processed or heat-damaged hair.
