K18 is bringing a giant rolling hairball made from 161 billion strands of hair to Sephora's Meatpacking District location on Wednesday, August 12, creating its largest public activation yet all in the name of hair longevity.

K18’s immersive pop-up celebrates the debut of its latest innovation, FutureIQ™ Serum, a breakthrough hair longevity serum powered by proprietary MultiVital™ Technology. ‘The Tumblehair’ will spotlight the scale of premature hair aging and everyday hair shedding across New York City's 8.5 million residents.

Attendees will step inside K18's Hair Longevity Lab and receive complimentary scalp analyses, connect with K18's education team for personalized product recommendations and hands-on product demonstrations, snap photos with (and even touch!) The Tumblehair, try their luck at a claw machine stocked with K18 prizes, and, with the purchase of FutureIQ™ Hair Longevity Serum, receive a complimentary scalp gua sha customized with on-site engraving.
