Living Proof is bringing its newest haircare innovation to Union Square with a playful, immersive pop-up celebrating the launch of Perfect hair Day™ Sheer Clean Dry Shampoo Mist. After teasing passersby with a mysterious "Nothing to See Here" Wig Wall on August 13, the experience officially opens on August 14, inviting guests to watch live product demonstrations and receive a complimentary full-size Perfect hair Day™ Sheer Clean Dry Shampoo Mist—handed through the wall by a mysterious hand—while supplies last. It's a fun, interactive way to discover the brand's revolutionary micellar-powered, non-aerosol dry shampoo with an invisible finish.

• Location: Broadway, between 17th and 18th streets
