The hairy croissant thart shocked the web: how a Thai bakery turned pastry into a global conversation

For centuries, the croissant has been celebrated as one of the world’s most elegant pastries. Golden, flaky, buttery, and unmistakably French, it has inspired countless reinterpretations, from rainbow-colored dough to extravagant fillings and towering hybrids. Yet few could have predicted that one of its most talked-about transformations would come from Thailand—and that its defining feature would be something resembling human hair (and not only…)

A bakery in Pattaya has found itself at the center of an unexpected international debate after introducing what customers have nicknamed the “hairy croissant.” The unusual pastry has quickly become one of the internet’s latest viral food sensations, dividing opinions while attracting curious visitors eager to see whether reality is as bizarre as the photos suggest.

The creation comes from Saiwan Bakehouse, a well-known bakery that has built a reputation for playful, visually striking desserts. Rather than relying on flashy colors or oversized portions, the bakery’s newest offering embraces illusion. At first glance, the croissants appear to be covered with coarse black hair, creating an image that many people initially find confusing—or even unsettling.
The effect is achieved using fat choy, an edible black algae scientifically known as Nostoc flagelliforme. Long appreciated in several Asian cuisines, fat choy has a naturally thin, thread-like appearance that makes it instantly recognizable. It is especially associated with festive dishes in Chinese cuisine, where its name sounds similar to the phrase meaning “to become wealthy,” making it a popular ingredient during Lunar New Year celebrations as a symbol of prosperity and good fortune.
Placed atop the buttery layers of a freshly baked croissant, however, the ingredient takes on an entirely different visual identity.

For many viewers, the resemblance is impossible to ignore. Social media users were quick to compare the strands to trimmed pubic hair, transforming the pastry from a simple bakery novelty into a full-blown online phenomenon. Photos spread rapidly across platforms, triggering thousands of comments that ranged from amused admiration to outright disgust.
Some critics argued that the bakery had crossed the line between creative presentation and shock value, accusing it of deliberately courting controversy to generate publicity. Others praised the concept as a clever example of visual humor, pointing out that the pastry contains nothing unusual or inedible despite its provocative appearance. To them, the joke lies entirely in perception: the ingredients remain perfectly ordinary, while the mind fills in the rest.
The bakery’s owner explained that the idea evolved from one of the shop’s earlier creations, a similarly unconventional “hairy cake” that had already demonstrated customers’ fascination with desserts designed to challenge expectations. Building on that success, the team adapted the concept into croissant form, producing a pastry that was instantly recognizable—and impossible to ignore.

The gamble paid off.

After local customers began sharing photographs online, international media soon picked up the story, introducing the unusual croissants to audiences far beyond Thailand. As images circulated across the globe, reactions became increasingly polarized, with countless people debating whether the bakery had produced an ingenious marketing masterstroke or simply one of the least appetizing-looking pastries ever created.
Ironically, the controversy has done exactly what every small business hopes for: it made people curious. Visitors have flocked to the bakery not only to taste the croissants but also to photograph them, turning the pastries into social media stars. Many customers admit that they ordered one purely because they wanted to experience the viral sensation for themselves.
The phenomenon highlights a broader trend in modern food culture, where visual impact has become almost as important as flavor. In the age of Instagram, TikTok, and short-form video platforms, restaurants and bakeries increasingly compete for attention by creating dishes that surprise, confuse, or even provoke. Whether it is charcoal-black ice cream, transparent coffee, cube-shaped watermelons, or hyper-realistic cakes that resemble everyday objects, the line between culinary craftsmanship and performance art continues to blur.

Psychologists have long noted that food presentation strongly influences expectations and even perceived taste. A dish that appears unusual—or deliberately unsettling—creates a conflict between visual instinct and rational understanding. The brain hesitates, even when it knows the ingredients are perfectly edible. That tension often becomes part of the experience itself, encouraging people to share their reactions online and fueling even more curiosity.
The “hairy croissant” taps directly into that phenomenon. Its success has little to do with exotic ingredients and everything to do with the power of first impressions. Once the initial surprise fades, customers discover what is, at its core, a buttery croissant topped with a traditional edible ingredient that has been enjoyed across Asia for generations.

Whether viewed as an inspired piece of edible comedy or an unnecessary exercise in provocation, the pastry has achieved something remarkably difficult in today’s crowded culinary landscape: it has become instantly memorable. In a world where thousands of new food trends appear every month only to disappear days later, a croissant covered with strands of black algae has managed to spark conversations across cultures, proving that sometimes the simplest recipe for viral success is a generous serving of curiosity, a dash of controversy, and impeccable timing.
