Let’s be real for a second. If you’ve spent more than five minutes on Stray Kids Twitter—or X, or whatever we’re calling it this week—you’ve seen the photos. You know the ones. They usually pop up under a "legendary k-pop visuals" thread or a random late-night "miss him" post. It’s Han Jisung blue hair imagery. It’s basically a rite of passage for every new STAY to fall down the rabbit hole of his 2020-era sapphire locks.
Honestly, k-pop idols change their hair more often than most of us change our bedsheets. We’ve seen Han with the classic "squirrel" brown, the icy blonde that makes him look like a prince, and the deep black that hits different during a rap verse. But blue? Blue was a whole cultural reset for the 3RACHA member. It wasn’t just a color; it was an vibe.
The Era That Defined "Bluesung"
A lot of people actually forget when this started. It wasn't just a random Tuesday. We’re talking about late 2020, specifically around the time of the Mnet Asian Music Awards (MAMA). Han Jisung showed up with this vibrant, electric blue that looked like it belonged in a sci-fi movie. It was sharp. It was loud. It was exactly what you’d expect from someone who produces tracks like "God’s Menu" and "Back Door."
Most fans refer to this as the "Bluesung" era. Short. Impactful.
He didn’t keep it for a massive three-year run, which is probably why people are so obsessed with it now. It was a flash in the pan. He had it during some of the most iconic performances of the Go Live and In Life cycle. When he stepped onto the stage for that MAMA performance, the contrast between the blue hair and the dramatic stage lighting made his rap sections feel ten times more aggressive—in the best way possible.

Why the Blue Hair Worked (When It Shouldn't Have)
Blue is a tricky color. If the tone is even slightly off, it can look a bit... DIY. But on Han, it highlighted his skin tone perfectly. K-pop stylists usually play it safe with pastels or deep navies, but this was a true, saturated cobalt.
It matched his energy. Han is known for being a "five-tool" player—he raps, he sings, he dances, he produces, and he’s a variety show king. The blue hair felt like a visual representation of that chaotic, brilliant energy. It was "Quokka" meets "Rockstar."
The Maintenance Struggle
You’ve probably wondered how he kept it that bright. Anyone who has ever touched bleach knows that blue is the devil to maintain. It fades to a murky green faster than you can say "Case 143."
While Han hasn't dropped a 10-step hair routine (we wish), industry experts like those at Jenny House—the salon often used by JYP artists—frequently mention the use of heavy-duty color-depositing shampoos and cold water washes. It’s a lot of work. He likely had to get touch-ups every two weeks to keep that specific vibrancy.

The 2025/2026 Resurgence
Wait, why are we still talking about this in 2026? Because the "DominATE" World Tour happened.
During the recent tour stops—like the massive show in Hong Kong—the "Bluesung" nostalgia hit a fever pitch. While he’s been rocking more natural tones and some experimental silvers lately, fans have been bringing "Blue Han" banners to every single stop. There's even been a spike in searches for Han Jisung blue hair because of fan-made "what if" edits going viral on TikTok using the latest AI style filters.
People are hungry for the return. It’s reached a point where the hair color is basically a character in the Stray Kids lore. It represents a time when the group was truly exploding into the global mainstream.
Comparing the "Blue" Members
Han isn't the only SKZ member to go blue. We have to acknowledge the competition here:

- Felix: Usually goes for a more ethereal, icy blue-silver.
- Hyunjin: Had that iconic dark navy during the Maniac era.
- I.N: Rocked a bright blue that felt very "maknae-on-top."
But Han’s was different because it felt gritty. It wasn't meant to look pretty or delicate. It was meant to look like he just finished a 48-hour session in the recording studio and decided to dye his hair on a whim. That authenticity is why it sticks.
How to Get the Look Without Killing Your Hair
If you’re sitting there thinking about heading to the drugstore to copy the look, hold on. Achieving Han’s level of saturation requires a very light base—basically a Level 10 platinum.
- Don't skip the bond builder. Products like Olaplex or K18 are non-negotiable if you’re bleaching to this level.
- Semi-permanent is your friend. Han likely used a professional-grade semi-permanent dye (like Manic Panic or Arctic Fox style, but pro-level) because it doesn't damage the hair further.
- The "Blue to Silver" Fade. Be prepared for the fade. Han’s hair often looked great even as it washed out into a dusty denim color.
Honestly, unless you have a JYP-level budget for salon visits, the best way to celebrate the Han Jisung blue hair legacy is probably through high-quality fanmerch or just keeping that iconic MAMA 2020 fancam on repeat.
If you’re looking to update your SKZ collection, your next move should be checking out the DominATE tour photobooks. They’ve tucked in some "throwback" style shots that lean heavily into these classic eras. Also, keep an eye on Han’s Instagram (@hab_and_k); he’s been teasing new music lately, and in the SKZ world, a new sound usually means a new hair color is lurking just around the corner.
