K18: Leave-In Molecular Repair Hair Mask

Powerful repair. Regenerated hair. Instant results.

The K18 Leave-In Molecular Repair Hair Mask is a revolutionary treatment that works at a molecular level to repair hair damaged by heat, bleach, chemical services, or everyday styling. Its innovative formula, powered by K18Peptide™, restores strength, elasticity, softness, and bounce to hair from the very first use — without weighing it down.

🌿 Key ingredients and benefits:

• K18Peptide™: a patented biomimetic peptide that rebuilds internal bonds (polypeptides and disulfide bridges), providing deep, lasting repair to the hair fiber.

• Optimized pH (5.0–6.0): helps seal the cuticle and restores the hair's natural resilience .

• Silicone and sulfate-free formula, lightweight and non-greasy, suitable for all hair types, even fine or color-treated.

✨ Key benefits:

• Repairs damaged hair fiber in just 4 minutes.

• Visibly lasting results, even after multiple shampoos.

• Hair is left stronger, softer, and more bouncy, with a silky finish — without any heavy buildup.

• A staple recommended by beauty editors as a science-backed hair essential.

🧴 How to use:

2. Apply 1 to 3 pumps depending on length and thickness, starting at the ends and working up toward the roots.

3. Let sit for 4 minutes without rinsing.

4. Style as usual (add styling products if desired).
