K18 Clean Streak Hair

This set contains three travel-sized essentials: the Peptide Prep Detox Shampoo, the Leave-In Molecular Repair Hair Mask, and the Molecular Repair Hair Oil. It is designed as a complete, multi-step system to cleanse, repair, and finish your hair.

K18 uses a patented bioactive peptide that travels into the innermost layers of the hair to reconnect broken keratin chains. By repairing the core structure rather than just coating the surface, it restores strength, softness, and elasticity.

While you can use them individually, they are formulated to work as a system. The detox shampoo clears away buildup so the leave-in mask can penetrate effectively, and the oil provides the final layer of smoothing and heat protection.

Yes, the K18 technology is designed to work on all hair types and textures, whether your hair is chemically treated, heat-damaged, or naturally fragile. Because the peptide works at a molecular level, it addresses damage regardless of your hair's specific structure.

For the best results, use the mask for the first four to six consecutive washes. After that, you can switch to a maintenance schedule, using it every three to four washes as needed to keep your hair strong and healthy.
