Unlike surface-only serums, it targets two levels of the hair fiber: reinforcing the inner structure and smoothing the cuticle exterior. The formula is silicone-free, weightless, and designed to layer easily into salon or at-home routines—use it after your K18 Molecular Repair Hair Mask or as a standalone finishing oil.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this oil actually reduce frizz throughout the day?\u003c\/h3\u003e\n\u003cp\u003eThe oil combines a peptide-led repair action with cuticle-smoothing emollients to both reverse damage and seal the hair surface.
