The biotech breakthrough in a travel-ready trial size. The K18 Leave-In Molecular Repair Hair Mask (15ml) is the perfect way to experience the revolutionary treatment that reverses hair damage in just 4 minutes. Whether you are looking to trial the technology or need a portable saviour for your holiday, this 15ml tube delivers the same permanent, molecular-level repair as the full-size icon.

Clinically proven to undo damage from bleach, colour, chemical services, and heat, K18 doesn't just mask damage—it reconnects the broken polypeptide chains and disulfide bonds within the hair fibre. The result is hair that is restored to its original strength, softness, and bounce.

Why You’ll Love It:

• The Perfect Trial: Enough product for multiple applications, allowing you to see the transformative results before committing to a larger size.
• Molecular Repair on the Go: A handbag-friendly size that ensures your hair remains resilient and healthy-looking wherever you are.
• 4-Minute Magic: A high-performance, leave-in treatment that works in minutes with no rinsing required.
• Universal Compatibility: Works on all hair types, from fine and virgin to highly processed and curly.
• Permanent Results: Because it mimics the hair's natural structure, the repair is lasting and won't wash away.

The Ingredient Powerhouse:

• K18PEPTIDE™: The patented molecular breakthrough that fits perfectly into broken keratin chains to reconnect them.
• Wheat Protein: Enhances moisture retention and provides a protective layer for a smooth, glossy finish.

Pro-Tip: For your first application, start with a small, coin-sized amount and add more only if needed. Because K18 is highly concentrated, a little goes a long way. Remember: skip the conditioner, apply to towel-dried hair, and wait exactly 4 minutes before styling.
