The 24-year-old GMMTV star joined the live GOHAIR talk show in Siam Square, sharing how his endorsement sold out 1,000 jars of product in under five minutes during an November 11 livestream. He sweetly answered how to express love without words, ‘I want to be with you for a long time. Let’s succeed together na’ – echoing lines from his on-screen partner William Jakrapatr. Est teased filming for their 2026 series ‘You Maniac’ next year and dreamed of long, martial-arts-hero hair, all while keeping his playful, genuine vibe.
The event took place on November 11 at the buzzing GOHAIR flagship studio, overlooking Siam Paragon, where Est, real name Suphawit Kittiwararak, sat relaxed in an oversized cream hoodie, his freshly styled long hair cascading over his shoulders – exactly the look thousands of fans had been begging him to keep since his breakout role in “The Sign”.
As soon as the host revealed that Est was the newest ambassador for the brand’s viral rice-water hair treatment, the countdown timer hit zero, and exactly 1,000 limited-edition jars emblazoned with his signature vanished from the online shelves in four minutes and fifty-two seconds.
Viewers watching simultaneously on TikTok and Shopee Live spammed heart emojis and “EST HAIR GOALS” in the chat. Between laughter and shy smiles, Est opened up about the quiet ways he shows love in real life. When asked how to say “I love you” without actually saying it, he looked straight into the camera and answered softly, “I want to be with you for a long time.
Let’s succeed together na,” a line that sent the studio audience into squeals because it was almost word-for-word the confession his character delivered to William Jakrapatr’s character in their upcoming 2026 series “You Maniac”.
The moment instantly became a viral sound on TikTok, with over 800,000 videos created in the first 48 hours, mostly couples recreating the scene in supermarkets, cafés, and university corridors.
Est also dropped the first official filming update for “You Maniac”, confirming that principal photography begins in February 2026 under the direction of Tee Bundit Sintanaparadee, the mastermind behind “I Promised You the Moon”.
He teased that the script is “crazy romantic but with actual martial-arts fight scenes,” and when the host asked about his dream hairstyle for the role, Est ran his fingers through his locks and grinned, “I want wuxia hero hair, super long, flowing in the wind while I fight on rooftops, like those old Chinese dramas P’William and I binge-watched together.”
The confession sparked immediate fan-casting threads imagining the two actors as sword-wielding soulmates, complete with AI-generated posters that racked up hundreds of thousands of likes.
Throughout the one-hour live, Est stayed true to the gentle, slightly chaotic energy fans adore. He accidentally spilt coffee on the white backdrop, tried (and failed) to pronounce the scientific name of fermented rice water, and ended up braiding a strand of his own hair on camera while explaining how the GOHAIR treatment helped him grow it past his shoulders after years of short cuts for previous roles.
When a fan called in asking for a birthday message, he sang “Happy Birthday” in the sweetest falsetto before adding, “Grow your hair long too, so we can match na krub!”
By the end of the broadcast, the brand announced an emergency restock of 5,000 additional jars exclusively for Thailand, set to drop on November 22, with Est’s handwritten thank-you note included in every package.
GOHAIR Thailand’s official Instagram posted a screenshot of the sold-out page with the caption “Est effect is REAL,” while Est reposted it on his account with a single teary-eyed emoji and the words “Thank you for loving my hair era.”
As 2025 draws to a close, the GOHAIR moment feels like the perfect prelude to what fans are already calling the “EstWilliam supremacy year” ahead. With “You Maniac” locked for a prime GMMTV slot and Est openly dreaming of martial-arts hero hair on live television, one thing is certain: whatever length his hair reaches in 2026, millions will be trying to grow theirs right alongside him.
For now, the boy who sold out 1,000 jars in five minutes continues to prove that sometimes the most powerful endorsement is simply being unapologetically, adorably yourself.
