K18 Leave-In Molecular Repair Hair Mask — Limited-Edition Future Society Scent, 1.7 fl oz, Peptide Repair in 4 Minutes

K18 x Future Society Leave-In Molecular Repair Hair Mask is a biotech peptide treatment that helps reverse chemical, thermal, and mechanical hair damage in four minutes and leaves strands smoother and more resilient.

This limited-edition collaboration blends K18's patented peptide technology with a bespoke fragrance inspired by extinct flower DNA developed by Future Society, creating a sensory-forward leave-in mask. The lightweight, concentrated cream targets hair at the molecular core rather than only treating the surface cuticle, making it effective across textures—from straight to coily—while adding detangling and softening benefits.

How does the K18 peptide actually repair broken hair structure?

The patented K18PEPTIDE is designed to mimic and reconnect the polypeptide chains and disulfide bonds inside keratin, helping restore elasticity and tensile strength lost from bleaching, coloring, and heat styling. It works within the cortex, so results differ from surface conditioners that only coat the hair.

• Peptide formulation engineered to integrate with keratin bonds
• Targets internal damage rather than solely the cuticle
• Visible improvement in elasticity and manageability after a few uses
• Non-rinsing leave-in cream for ongoing protection and resilience

How do I use this leave-in mask for best results?

Apply K18 x Future Society on clean, towel-dried hair—skip conditioner after shampoo. Distribute 1–3 pumps depending on length and thickness, leave on for four minutes, do not rinse, and style as usual. Use it for 4–6 consecutive washes initially, then as needed for maintenance.

• Start with 1 pump for short hair; increase for medium or long lengths
• Apply to roots through ends for full-length repair and detangling
• Wait four minutes—no heat or rinse required—then proceed to styling
• Initial course: use for several washes to build molecular repair benefits

Will this product work on my hair type and color-treated strands?

Yes—because K18 acts on the hair's inner structure, it is formulated to help a wide range of hair types, including color- and bleach-treated hair as well as curly and coily textures. It complements chemical services by addressing bond integrity rather than simply masking damage with heavy oils.

• Safe for bleached, colored, and chemically treated hair routines
• Effective across straight, wavy, curly, and coily textures
• Boosts manageability and reduces tangles for easier styling
• Compatible with regular heat styling when used as directed

What sensory experience does the limited-edition scent provide?

The Future Society fragrance is a curated, biotech-inspired aroma derived from the collaboration concept of extinct flower DNA, designed to add a subtle, modern floral layer to the treatment experience. The scent complements the lightweight formula without weighing hair down or leaving heavy residue.

• Limited-edition audio-sensory concept: floral, nuanced biotech-inspired scent
• Lightweight fragrance that fades naturally after styling
• Formulated to avoid heavy masking or greasy buildup on strands
• Enhances the treatment ritual without altering product performance

Who is this for? This K18 x Future Society Leave-In Molecular Repair Hair Mask is aimed at people seeking scientifically driven repair for chemically or heat-damaged hair who want quick, visible improvement without rinsing. It suits those with color-treated, bleached, or naturally textured hair who prefer a lightweight, leave-in treatment that builds strength and smoothness in a few applications, plus anyone interested in a limited-edition scent collaboration that enhances the at-home treatment ritual.
