A weightless, humidity-halting spray with ingredients that help protect hair from UV damage and stop frizz in its tracks for up to 72 hours of heat-safe, silky-smooth strands.

Frizz Block Smoothing Spray creates an impenetrable veil of humidity-blocking, frizz-stopping, moisture-locking mist that protects strands for up to 72 hours. Created for harsh humid conditions, this alcohol-free, heat-activated spray is the prescription-strength equivalent of traditional anti-frizz sprays.

Our proprietary Alpha Keratin 60ku instantly fills and seals cracked cuticles while featherweight polymers and lipids hover above, repelling humidity. This lightweight, milky mist is alcohol free, so it will not create buildup or dry out hair, and it is heat protective up to 450 degrees, leaving hair healthy, silky-soft, and free of frizz for days.

Clinically proven to immediately reduce frizz by 59% and offer frizz reduction that lasts up to 72 hours without diminishing over time.
