How safe is it?

Product Description

Nothing ruins a good hair day faster than a bad case of SFO: Sudden Frizz Onset. Unlike most anti-frizz products—which can weigh down hair with silicones and oils—this award-winning shampoo battles the leading causes of frizz in a totally new way. The brand's patented molecule, OFPMA, creates a weightless shield around strands, blocking humidity and smoothing the hair shaft to reduce friction during styling. The sulfate-free cleanser also repels dirt and oil—so you can go longer between washes.

Hang tight. We're thinking.
