If you’ve read about Living Proof in the past, chances are you’ve come across the name of our proprietary No Frizz molecule, PolyfluoroEster. While the name may sound scary, the molecule itself is quite remarkable.
Our scientists began by examining the causes of frizz and then determined how to prevent it from even forming. Their conclusions were twofold:
- Prevent humidity from penetrating: Create an exquisitely thin, smooth layer that perfectly coats and shields the hair.
- Reduce friction between fibers: Produce a surface on the hair with as low of a surface energy as possible.
They wanted to solve these two problems from a physics standpoint, so they steered clear of traditional anti-frizz technology. After exhaustive research and experimentation, PolyfluoroEster was born!
PolyfluoroEster is a smaller molecule than the traditional materials used to control frizzy hair, namely silicone. Due to its chemical nature, the formulation adheres tightly to the hair, which allows for long-lasting moisture resistance and rebalancing of the hair fiber’s interaction with the atmosphere, even after extreme humidity. In fact, repeat use after shampoo seems to improve the hair’s own ability to resist humidity change, and our product seems to keep working better.
No Frizz also had some benefits we didn’t anticipate (but our scientists seem happy to take credit for). Due to its low surface energy, it repels most other materials like dirt. As a final benefit, the surprisingly low refractive index of the coating produces a unique, long-lasting shine and “pop” in the color of the hair.
Not bad for such a tiny molecule, right?
