The K18 Professional Molecular Repair Mask is a groundbreaking, leave-in treatment that doesn’t just coat the hair—it heals it from the inside out.
Unlike traditional masks that only soften the surface, K18 uses a patented peptide (K18Peptide™) that travels deep into the inner layers of the hair shaft to reconnect broken keratin chains caused by bleach, color, heat, and chemical services.
In just one treatment, your hair will feel stronger, softer, smoother, and noticeably healthier—with results that improve over time.An add-on treatment during your color or lightening service
Perfect for:
An add-on treatment during your color or lightening service
