Living Proof Perfect hair Day (PhD) In-Shower Styler is an innovative styler that is applied in the shower and lightly rinsed creating air-dried styles with enhanced body, softness, natural texture and shine. This first-of-its-kind formula is designed to be applied in shower and lightly rinsed, leaving behind cationic resins that bind to the hair and flex when dried, so they enhance your hair's natural texture. Their patented Thickening Molecule (PBAE) deposits thickening dots on your hair fibers to create body and fullness. Magnetic texturizers build separation between your hair fibers to enhance your waves, and a hydrophobic resin controls flyaways and adds shine. The result: your hair will air dry with enhanced body, softness, natural texture and shine.
