Living Proof Style Lab Flex Hairspray Review: Is It Worth It?

VYRDICT: Mostly Worth It — Worth 77/100.

🔥 Viral 78/100✓ Worth 77/100Mostly Worth It

A strong option for people who hate crunchy hairspray. Independent long-wear testing supports flexible hold and heat-styling use. Not the right choice when maximum stage-level hold is the priority.

What it does
