Living Proof Perfect Hair Day (PhD) 5-in-1 Styling Treatment, Multitasking Leave-In Styler for Smoothness, Volume, Strength & Shine

Ticking off a number of boxes in one simple step, this hardworking formula is designed to help treat and style your tresses at the same time. Enriched with the brand's patented Healthy Hair Molecule (OFPMA), the clever formula repels dirt and oil so hair stays cleaner and protected for longer. This ingenious ingredient also smooths hair weightlessly for easy detangling and fullness, all while sleeking frizz by blocking humidity (cool, huh?). Also in the mix is the brand's other patented ingredient: the Thickening Molecule (PBAE). This proprietary technology mimics the look and feel of thicker hair, by depositing a flexible and virtually indestructible ‘web’ between strands. Hair feels soft and naturally fuller – and you can comb, style and run your fingers through it, without any risk of deflation. These ingredients in unison deliver five benefits in one hit: smoothness, volume, conditioning, strength and polish.
