Paul Mitchell Extra-Body Root Boost is a lightweight volumizing spray made for fine, limp hair, applied at the roots on damp hair before blow-drying. Panthenol in the formula adds body to strands, while a VP/VA copolymer blend provides lift and hold that brushes out easily rather than leaving a stiff, over-sprayed feel. Its precision nozzle is designed to target the spray directly at the scalp instead of coating the length of the hair. The formula is paraben-free and vegan, and is labelled safe for color-treated hair. It's meant to be used as a base layer under a round-brush blowout for hair that needs extra root lift and body through the day.
