New Yorkers have seen it all. A rat riding the subway. A tornado hitting Rockaway Beach. A naked cowboy serenading Times Square. But what about a ten-foot-wide, 180-pound ball of matted, tangled hair barreling down the streets, avenues, and alleyways of the city?
Well, that’s exactly what baffled residents witnessed when NYC was infiltrated by one giant hairball. Causing a complete social media frenzy, biotechnology haircare brand K18 quite literally rolled out its campaign for its new FutureIQ Biomimetic Hair Longevity Serum—its most expensive product yet, at $120 for 3 ounces—last week.
The hairball, dubbed the “Tumblehair,” served as a tangible way to visualize the 167 billion strands that New Yorkers could collectively retain over 90 days of using the serum, according to the brand. “Hair longevity can be an invisible concept, so we wanted to bring the science behind our new product to life in a way people couldn’t simply scroll past,” Kleo Mack, K18’s Chief Marketing Officer, told BeautyMatter.
Only a hairball could get grown men in suits taking selfies, tourists doing double-takes, and even police officers stopping in their tracks to revel at this beastly object. Early figures from the brand have already reported that the campaign secured over $6.62 million in earned media value, reaching more than 15 million users on social media, with 98.1% of that driven by user-generated content.
Still, the Tumblehair was designed to do more than generate social impressions. While the rolling spectacle created a highly shareable, top-of-funnel moment, its journey ultimately led to Sephora's Meatpacking District location, where K18 hosted its Hair Longevity Lab pop-up. This turned curiosity into an opportunity for consumers to learn about the brand and experience the new serum firsthand.
Unsurprisingly, pulling this off wasn’t easy. Uncommon Creative Studio, the agency that concocted this creative idea, partnered with prop stylists CAD Industries and Decimated Designs to gather both real and synthetic hair, much of which came from K18’s partner stylists’ salons, before hand-styling, sewing, and constructing the ball. This engaged the brand’s professional community in an activation meant to draw shoppers into Sephora.
“We wanted to make sure that all of the hair that we were using felt representative of the population of New York,” Cara Johnson, Creative Director at Uncommon, told BeautyMatter. Using various colors, styles, and textures, the creative team wanted the hairball to look “as gnarly and crazy as a real ball of hair would look if it had been slowly collecting hair and rolling around the city for God knows how long.”
The next step was getting the City of New York and the mayor’s office to approve the permits needed for an object as big as a car to roll along the sidewalks of Manhattan.
Which begs the question: How on earth was this monstrous thing even rolling?
A five-person production crew of “flaggers,” as Johnson referred to them, rolled and steered the Tumblehair across the city, ensuring it wouldn't casually fall straight into the East River. The ball hit highly-trafficked areas including Midtown, the West Village, Chinatown, and the Seaport before arriving at the Meatpacking District. Here, the Longevity Lab offered consumers complimentary scalp analyses, product demonstrations, educational sessions, and customized scalp gua shas for those who purchased the serum.
Johnson credited K18 for being “very savvy, very brave, very down to make noise.” It's not every day that brands are willing to take a leap of faith and approve unbranded stunts.
But that’s precisely what made the Tumblehair work. At a moment when beauty brands are constantly activating, whether that’s handing out free products or collaborating with the hottest stars, this stunt went beyond simply generating buzz. It also allowed the brand to reach people far beyond the traditional beauty customer: everyday passersby and casual social users naturally wanted to take part in the conversation.
“At a moment when consumers are increasingly questioning what’s real versus digitally created, there’s something incredibly powerful about taking an absurd idea, physically building it, and putting it directly into culture,” said Mack.
Experiential marketing is having a moment, even specifically when it comes to faux hair. Living Proof recently took over Union Square with an oversized wall of hair to promote its newest dry shampoo, letting New Yorkers touch and feel the hair before mysterious hands reached through and delivered free samples.
But K18 took its stunt one step further: The hairball reached influencers. A select group received a sleek, silver reflective box that contained… their own personal mini Tumblehair. Surprise!
“Influencers are used to getting this beautiful package and opening it up and seeing all these amazing products and beautifully crafted gifts,” said Johnson. “We thought that they would be a little bit more shocked and intrigued by this miniature ball of hair that's still gorgeously packaged.”
For brands like K18, it can be difficult to communicate their science-first formulations to the everyday consumer. Activations like this one allow the brand to get people to care about the science, too, and give a visual representation of why it matters.
“When the creative idea is rooted in a real product truth, education and entertainment don’t have to compete. You can deliver both at once,” said Mack.
