What it is: A weightless hairstyling primer that protects and extends the life of your style. What it does: Prime Style Extender, powered by Living Proof’s “miracle molecule,” OFPMA, protects and extends the life of your style twice as long, saving you time, day after day. It weightlessly perfects strands while smoothing and correcting hair texture. Prime detangles, corrects cuticle texture, and is so perfecting it can be worn alone, yet so weightless it can be layered under your favorite styler. Save time and forget the touch-ups.
