Leave-in hair mask

K18 Leave-In Molecular Repair Hair Mask is more than just a treatment—it’s a breakthrough in hair repair science. This leave-in mask works on a molecular level to reverse damage caused by bleach, color, chemical services, and heat styling. Powered by the patented K18PEPTIDE, it doesn’t simply condition or coat the hair - it travels deep into the inner cortex to reconnect broken keratin chains and restore hair's original structure. The result? Visibly healthier, stronger, smoother hair in just four minutes. No rinsing required, and no need to pile on layers of product.

 

Why this mask?

• Here’s what makes it stand out: it’s the only product that both reconnects polypeptide chains and repairs disulfide bonds, giving hair a more complete kind of recovery.
• The formula is clinically proven to renew strength and elasticity across all hair types and textures.
• Plus, the results don’t wash away. With continued use, hair continues to improve, feeling soft, resilient, and salon-fresh even after multiple washes.
• It’s lightweight, non-greasy, and doesn’t leave any buildup behind, making it ideal even for fine or oily-prone strands.
• The real win? It simplifies routines - no rinse, no downtime, no masking damage with heavy conditioners.

 

How to use?

• To use, start by shampooing as usual but skip the conditioner.
• Towel-dry hair thoroughly, then apply 1-3 pumps of the K18 mask, depending on hair length and thickness.
• Work the product evenly from mid-lengths to ends, adding more if needed.
• Now, here’s the key part: wait four full minutes before adding any other products or styling. This is the activation phase where the peptide works its magic.
• After four minutes, style as usual.
• For best results, use for the first 4-6 consecutive washes after a chemical service, then switch to maintenance mode as needed.
• Simple, powerful, and science-backed, this is hair repair that actually lives up to the hype.
