If you live in Metro Vancouver, you already know: the air does something to your hair. Coastal humidity raises the cuticle and allows moisture to move in and out unevenly — the root cause of frizz and puffiness that starts smooth and expands through the day. A professional smoothing system works differently from a drugstore anti-frizz product because it seals the cuticle at the right pH, deposits emollients that stay put under humidity, and provides a finish coat that resists re-absorption. At Zennkai we carry the full professional smoothing ranges — Kérastase, Redken, Davines, Living Proof, Amika, and more — curated by concern, hair type, and the specific humidity conditions of the Lower Mainland.
