Living Proof Style Lab Flex Hairspray 3.0 Oz (Pack of 2)

Living Proof Style Lab Flex Hairspray is a revolutionary, science-backed aerosol styling spray engineered to set, style, and finish hair with medium hold that never goes stiff, crunchy, or greasy. At the core of its formula is Living Proof's proprietary Flexible Web Technology — a precision-optimized blend of firm and flexible polymers (Polyurethane-14 and Octylacrylamide/Acrylates/Butylaminoethyl Methacrylate Copolymer) that creates a lightweight polymer network around each strand rather than coating hair in heavy resins, delivering hold that moves naturally with your hair. A conditioning emollient complex (Polyglyceryl-10 Pentaoleate and PPG-5-Ceteth-20) adds genuine lubricity, brushability, and luminous shine, so strands stay soft and manageable rather than locked in place. Panthenol (Vitamin B5) acts as a humectant that strengthens the hair fiber, hydrates, and improves elasticity — helping minimize breakage and shield hair against damage from repeated heat styling. The formula is completely silicone-free and oil-free, so it builds freely over multiple applications without weighing hair down or leaving any sticky residue, making it ideal for fine-to-medium hair that typically suffers under conventional sprays. It provides reliable heat protection up to 410°F/210°C, making it fully compatible with blow dryers, curling irons, and flat irons. Safe for color- and chemically-treated hair and suitable for all hair textures — straight, wavy, curly, and coily — it finishes with a light, fresh citrus-leaning fragrance. This pack of two 3.0 oz bottles is perfectly sized for travel or everyday use at home or on the go. How to Use Shake well before each use. Hold can 6–10 inches from hair and apply in a sweeping motion — spray on damp hair from roots to ends before blow-drying to build a structured base, or mist over dry hair and style with your preferred heat tool. For a finished look, spray over your completed style for flexible, touchable hold. Layer freely as needed without fear of buildup or stiffness.
