Defy Frizz: Matrix Mega Sleek 96H Anti-Frizz Topcoat Serum

Frizz Happens, No Matter Your Hair Type or the Season
From gym sweat to steamy showers: frizz is everywhere
Whether you're powering through a spin class, running errands, or just stepping out into a humid morning, frizz finds a way. From low humidity static and wispy flyaways to high humidity poofiness and fluff, it doesn’t discriminate. Even a steamy shower or your morning commute can undo a 40-minute blow-dry in 5 minutes. Frizz is real and so is the frustration.

Say goodbye to frizz in every form. The new Matrix Mega Sleek 96H Anti-Frizz Topcoat Serum delivers days of smooth, frizz-free control, no matter your texture or environment, with lasting effect proven to last up to 5 shampoos.

Just one drop is all it takes to seal, smooth, and defy humidity with zero fluff, poof, or static left behind.
