PRODUCT OVERVIEW

A lightweight, flexible hairspray that delivers touchable medium hold, heat protection up to 410°F, and brushable, reworkable style without stiffness or buildup.

Living Proof Style Lab® Flex Hairspray is a multitasking styling spray designed to set, style, and finish hair while maintaining natural movement and touchability. Unlike traditional hairsprays that can leave hair stiff, crunchy, or difficult to restyle, Flex Hairspray delivers medium-level hold that remains flexible, brushable, and reworkable.

Powered by Flexible Web Technology, the lightweight formula creates a flexible network of polymers around the hair to provide reliable hold without coating strands in heavy resins. The result is weightless structure and control that can be layered throughout the styling process without stiffness, flaking, or greasy buildup.

More than just a finishing spray, Flex Hairspray can be applied to damp or dry hair and provides heat protection up to 410°F / 210°C, allowing it to function as a styling spray, heat protectant, and finishing hairspray in one. It also helps styles stand up to humidity and frizz while remaining soft and touchable.

HOW TO USE

Spray onto damp or dry hair and style with your desired heat tool.

For additional hold, spray onto the finished style.

For best results, hold the can approximately 10–12 inches away from the hair and apply in a light, even pass. Build additional layers as needed for more control without stiffness.

When creating a blowout or heat-styled look, lightly mist individual sections before styling. For finishing, apply one or two light passes over the completed style.
