K18 Leave-In Molecular Repair Hair Mask (5 oz / 150ml)

Transform damaged, brittle hair into smooth, strong, and healthy-looking strands with the K18 Leave-In Molecular Repair Hair Mask. This breakthrough treatment uses patented biomimetic peptide technology to repair hair from the inside out—restoring strength and elasticity in just 4 minutes.

Unlike traditional masks that only coat the surface, K18 works deep within the hair structure to reconnect broken keratin chains caused by bleaching, coloring, chemical treatments, and heat styling.
