K18 Leave-In Molecular Repair Hair Mask – 50 mL

Give hair stressed by bleaching, coloring, chemical services, or heat styling a simple repair step. K18 Leave-In Molecular Repair Hair Mask is a concentrated treatment powered by K18PEPTIDE™. It is designed to help strengthen damaged hair while improving its softness, smoothness, and bounce.

Unlike a traditional mask that you rinse out, K18 stays in your hair. Apply it after shampooing, wait four minutes, and continue with your usual styling routine. Its lightweight cream formula works across hair types and textures without adding another rinse step.

Benefits
Targets chemical and heat damage: K18PEPTIDE™ is designed to address damage associated with bleach, color, chemical services, and heat styling.
Helps hair feel stronger: The treatment supports hair strength and resilience, especially when hair feels weakened or overprocessed.
Improves softness and smoothness: Helps rough-feeling hair feel softer and more manageable, with a smoother, bouncier appearance.
Fits into a quick routine: The leave-in formula needs four minutes before you comb or style. There is no need to rinse it out.
Suitable for all hair types: Use it on straight, wavy, curly, or coily hair; adjust the number of pumps to your hair’s length and density.
How to use
Shampoo your hair. Do not apply conditioner before the K18 mask. Conditioner can coat the hair and interfere with how the treatment works.
Towel-dry thoroughly. Hair should be clean and damp rather than dripping wet.
Apply 1–3 pumps. Start at the ends and work upward toward the roots. Use the amount that suits your hair’s length and density; more product is not necessarily better.
Wait the full four minutes. Leave the mask in your hair. Do not rinse it out, comb, or add styling products during this time.
Style as usual. After four minutes, comb your hair and add any conditioner, leave-in, or styling products you want.

For progressive results, use the mask for 4–6 consecutive shampoos, particularly after a salon chemical service. After that, use it as needed to maintain your routine.
