OLAPLEX Shape Set Hairspray is a buildable, medium-hold finishing spray that keeps styles flexible and controls frizz for up to 96 hours. Its dry-touch finish stays brushable without crunch, flakes, or stiffness, while adding shine. Bond Set Technology helps strengthen hair by reconnecting broken disulfide bonds, and Flexi-Hold Polymers help preserve shape through humidity. Layer the spray to build the hold you want. It also provides heat protection up to 450°F/232°C for restyling. Color-safe and vegan, it is suitable for chemically treated hair.
