What it is: A smoothing styling spray that eliminates frizz by blocking humidity without weighing hair down.What it does: Living Proof No Frizz Weightless Styling Spray is the first new anti-frizz technology in over 30 years that doesn’t rely on silicones or oils. Instead, No Frizz derives performance from Living Proof’s “miracle molecule,” PolyfluoroEster, to create a weightless shield on hair that blocks humidity absorption, smooths the cuticle, and repels dirt. The PolyfluoroEster shield is established over the first five uses of the No Frizz regimen, so it becomes stronger, the longer you use it and can be maintained with consistent use of No Frizz products.What it is formulated WITHOUT:- Parabens- Sulfates- Synthetic Dyes- Petrochemicals- Phthalates- GMOs- TriclosanWhat else you need to know: No Frizz Shampoo, Conditioner and Leave-in create a healthy foundation and help block humidity, while the No Frizz Stylers complete the shield to stop frizz in its tracks. By using the complete regimen, your hair will be so protected it will block humidity and stop frizz even on the days you don’t wash and style. Stylers deposit even more PolyfluoroEster because they are leave-on versus rinse-out products.
