Sleek Finish Serum

Frizz is caused by the hair cuticle lifting in response to humidity — and Sleek Finish Serum addresses this at a molecular level. Our HumidaShield technology creates an ultra-thin, breathable film around each strand that flexibly bends rather than breaks in humid conditions, keeping the cuticle flat and smooth for up to 48 hours. The result is that impossibly smooth, glass-like finish you see on magazine covers — achievable at home, in minutes. The serum-to-oil texture transforms from a light fluid on your palm into a weightless veil the moment it contacts hair. No build-up, no greasiness — just pure, brilliant, undeniable shine. Perfect as a final step after any styling routine, or used alone on freshly air-dried hair for an effortlessly polished look.
