Entry Information
Summary
For decades in Vietnam, "Smooth as Sunsilk" was no longer advertising. It became everyday language to describe anything effortless and satisfying - smooth moves, smooth deliveries, smooth experiences. However, while the brand slogan remained famous, younger audiences feel less desirable for the Sunsilk brand. Instead of creating a new slogan, Sunsilk expanded its most iconic brand asset into Silktopia: a surreal entertainment universe where smoothness is the law of existence. Chess pieces have silky hair. Hair becomes a badminton racket. Everyday moments unfold with impossible ease. Powered by a hypnotic "Smooth as Sunsilk" soundtrack, the campaign transformed a legendary hair claim into a cultural playground for a new generation and made "Smooth as Sunsilk" ownable again.
Strategy
"Smooth as Sunsilk" is one of Vietnam's most iconic advertising lines. For years, people had adopted it into everyday conversations, to describe anything that worked seamlessly. But while the phrase remained famous, its connection to the brand was fading among younger audiences. Rather than replacing the asset, we identified an opportunity to make "smooth" go beyond just hair benefit. Our simple strategy: if people already used "Smooth as Sunsilk" to describe life, Sunsilk would create a world where smoothness governed life itself. Instead of advertising smoothness, we turned smoothness into entertainment. This allowed Sunsilk to reconnect with younger audiences through participation, humor and social sharing, while reinforcing core product truth in a fresh and memorable way.
Execution
We created Silktopia, a universe where smoothness governed everything. The campaign launched with a surreal film built on absurdly smooth logic. Every scene exaggerated the meaning of "smooth", transforming ordinary moments into entertaining spectacles. At the centre was Phùng Khánh Linh, a Gen Z-loved singer known for her iconic long, silky hair. Bridging music, beauty and internet culture, she helped turn Sunsilk's legendary asset into something contemporary and socially native. A looping "Smooth as Sunsilk" soundtrack connected every scene, turning the brand's legendary line into Silktopia anthem. The world then expanded through social conversation, creator remixes, and audience participation at a real-life festival - proving a beauty brand could build culture from its own asset.
Results
As a result, Silktopia generated 21.7 million views and increased organic impressions by 221%. The campaign increased Sunsilk's Social Share of Voice by 400%, making it the No.1 haircare brand on TikTok and Meta. Brand impact was equally significant, doubling Ad Recall versus the previous month. Most importantly, entertainment translated into business performance, contributing to an 18.4% increase in sales performance (YTD April 2026). By transforming a decades-old slogan into an entertainment universe, Sunsilk proved that iconic brand assets don't need reinvention. They need a world people want to play in.
