About this item

Highlights

  • The 5 oz size delivers excellent value and is ideal for salons or individuals committed to a long-term repair routine. A little goes a long way, thanks to its concentrated, high-performance formula. Each bottle supports multiple treatments without compromising on quality.
  • Whether your hair is straight, wavy, curly, coily, fine, or coarse, K18 adapts to repair damage across all textures. It’s lightweight enough for fine hair and powerful enough for thick or processed strands. Safe for color-treated and chemically-treated hair.
  • Unlike traditional hair masks, K18 is designed to be left in—no rinsing required—so it continues to work even after application. Just shampoo, towel-dry, apply, and wait 4 minutes before styling. It simplifies your haircare routine while delivering professional-grade results.
  • Perfect for chemically lightened or color-treated hair, this mask delivers visible improvement in softness, shine, and strength. It helps restore elasticity and reduces breakage after harsh salon services. Ideal for both first-time and long-term users of chemical treatments.
  • K18’s patented peptide technology travels deep into the cortex to reconnect broken polypeptide chains (keratin bonds). This strengthens hair from the inside out, reversing years of damage from bleach, color, and heat. It’s a true molecular breakthrough—not just surface-level conditioning.

Description

Bring damaged hair back to life with the K18 Biomimetic Hairscience Professional Molecular Repair Hair Mask, a breakthrough treatment that reverses hair damage at a molecular level. This leave-in, no-rinse mask uses K18’s patented biomimetic peptide technology to reconnect broken keratin chains — the building blocks of hair structure — restoring strength, smoothness, and elasticity in just 4 minutes. It’s clinically proven to reverse damage from bleach, color, chemical services, and heat.

Unlike traditional conditioners or masks that only coat the surface, K18 goes deeper, repairing the inner structure of hair for lasting results. It works on all hair types and textures, especially those that have undergone repeated chemical or heat treatments. After one use, hair looks and feels healthier, softer, and more resilient — and results only improve with continued use.

The 5 oz professional size is perfect for salon treatments or long-term personal use. Lightweight and non-greasy, this leave-in formula is easy to apply and integrates seamlessly into any wash routine. If you’re looking for real molecular repair, not just temporary softness, K18 is the ultimate damage-reversing solution trusted by hair professionals worldwide.
