2PCS-K18 Leave-In Molecular Repair Hair Mask 5 oz/150ml
Key item features
- This leave-in mask leverages the patented K18Peptide™, a biotech-engineered compound that mimics the natural keratin structure. In just four minutes, it penetrates to the hair's core—reconnecting broken polypeptide chains and disulfide bonds at the molecular level. This delivers renewed strength, elasticity, smoothness, softness, and bounce that lasts beyond just one wash.
- Designed to reverse the effects of bleach, color treatments, chemical services, and heat damage, this mask provides both immediate and lasting repair. Its effectiveness has been clinically validated, giving stylists and users confidence that even over‑processed, weakened strands can be restored to a healthier state with consistent use
- The creamy texture of the mask allows for effortless, lightweight application on damp hair after shampooing—no rinse required. Within just four minutes, it delivers transformative results, simplifying the salon or at-home routine and saving time without compromising repair performance.
- Because it works at a molecular level—the foundational structure common to all hair—the mask is universally effective, whether hair is straight, curly, coily, fine, or thick. It's also vegan, color-safe, cruelty-free, and formulated with a gentle pH optimized (around 5–6) to promote cuticle resilience and minimize swelling.
- Esteemed as a top-tier leave-in mask by leading beauty publications, Vogue highlights its fast-acting peptide technology and ability to lower pH (keeping cuticles tight and preserving color and moisture) while stylists like Travis Ogletree report visible, manageable improvements in client hair. The light floral scent (jasmine and peony notes) adds a luxurious sensory touch.

About this item
Product details
Professional, at-home hair treatment mask with a patented peptide. K18 Leave-In Molecular Repair Hair Mask 5 oz repairs and restores your keratin levels while strengthening the cuticle of each strand from root to tip for more youthful vibrancy! A cupboard full of products can't give you the results that K18's new leave in treatment does! When it comes to damage control, this is all you need. This easy-to-use formula penetrates deep into your strands for repair on every level. The microscopic level where Keratin meets Keratin is restored by K18Peptide so less breakage occurs. Alongside repairing damaged proteins, there's a conditioning ingredient that strengthens any weakened or brittle areas.

Hair feels amazing and comfortable.
I use it as my every time conditioner because I have very fine, very dry hair. It makes my hair feel thicker and comfortable. What's amazing is it's about 1/20th the cost of Amazon for the very same product in a much smaller size. No more static hair!
