To achieve lift and height, the majority of root lifting sprays rely on 1 one stiff, brittle resin to prop hair up at the roots. Unfortunately, the most commonly used holding resins are dry, hard, and brittle, and flake away with every touch and movement, causing hair to collapse far too quickly. Some root lifting sprays have tried to improve on this by using flexible resins, however, flexible resins are too weak to create lift at all leaving limp hair with no body. Living Proof scientists knew they would have to develop a solution that would be both strong and flexible for any texture or hair type whether that be thick hair or thin hair. Thus they created a unique blend of resins, never before used in a root lifting spray, to meet both of these characteristics: strong enough to provide long-lasting lift, yet flexible enough so that the lift wouldn't collapse when exposed to one's daily activities. The scientists also discovered that adding PolyfluoroEster reduces surface tension for an even deposition of the resin film.
