Why does Sasuke not wear his headband

Sasuke's headband is light blue, sort of sky-ish colour, boruto's is pure black, if you rewatch the scene I think you'll be able to see the difference.

According to Pain a ninja puts a mark through his headband indicates that s/he has given up or betrayed their village. Two possibilities, either boruto is wearing sasuke's headband or he will eventually betray the village. Keep in mind that sasuke's headband was BLUE. #Boruto pic.twitter.com/zVv4bWgJrm

Boruto: Naruto Next Generations has finally revealed how Boruto ends up with Sasuke's headband. It's a mystery that's been hanging over the series since its opening flash-forward scene, which saw a teenage Boruto wearing Sasuke's headband into battle against his friend/rival Kawaki, with Hidden Leaf Village seemingly in rubble behind them. Ever since seeing that scene play out, Naruto fans have been convinced that part of Boruto's story will inevitably be the reveal of Sasuke's tragic fate. And after the latest Boruto manga chapter, fans aren't exactly feeling more reassured, as Sasuke passing his headband to Boruto seems like dark foreshadows of what's about to come.

Warning! Boruto chapter 49 SPOILERS Follow!

The latest chapter of Boruto picks up from the cliffhanger of Isshiki Otsutsuki launching a sudden attack on Hidden Leaf Village. Thanks to some key double-crossing within the Kara criminal organization, Isshiki was forced to abandon Jigen, the human vessel he had been hiding in, and reveal his true Otsutsuki form in battle. That transformation has left Isshiki uniquely vulnerable; Jigen is an imperfect vessel, and it is only Kawaki that can fully contain Isshiki's essence before it burns Jigens body out and causes the Otsutsuki warlord to die.

With that ticking clock hanging over him, Isshiki makes haste to Hidden Leaf Village and starts killing off villagers, to draw out Kawaki. Being the Hokage, Naruto meets Isshiki in battle face-to-face, in the skies over Konohagakure. However, as the "Shadow Hokage," Sasuke has a different plan, entirely.

While Naruto is fighting, Sasuke takes Boruto aside for a "pep talk." Sasuke has been paying close attention to the revelations about the Karma seal and its purpose as the Otsutsuki's method of resurrection; he knows that during Team 7's rescue of Naruto, Boruto's Karma seal allowed Momoshiki Otsutsuki to unleash terrible power in the young boy. Now Sasuke wants Boruto to do it again - only this time, by unleashing the might of Momoshiki against Isshiki! Naturally, Boruto is a bit shaken about rushing into battle against Isshiki, and makes one big request of his mentor:

"Remember last time, when we went to rescue dad from Momoshiki, you lent me your headband? Can I borrow it again?"

Sasuke hands over the headband, understanding what it means to Boruto. He even finds his own way to let Boruto know that he cares about him (or at least the headband):

"It's valuable," Sasuke tells Boruto. "So you better return it in person."

Boruto promises to do so - but it feels increasingly likely that the promise will not be able to be kept. Naruto, Sasuke, and Boruto are now in another dimension to fight Issihiki, with everyone ready to unleash their respective full powers. While Sasuke's passing of the headband seems like it could be purposeful misdirection, the power of Isshiki makes it seem more like this could truly be the end of Sasuke Uchiha.

Could you explain to me why the head thing naruto had ( sasuke one ) is so important? More like, why did he give it back to sasuke when he was leaving? And why did sasuke wanted to take it until things settled between them? I'm missing something really important here D:

la-sasuke answered:

Sasuke’s headband, huh? Unlike Naruto who sees it as a sign of acknowledgment, to Sasuke, Konoha headband had no special value until he made it about his bond with Naruto.

In their first battle on the hospital roof, Naruto told Sasuke to put his headband on before they fight, but Sasuke refused and said, “I don’t need something like that.” Naruto then explained, “I’m saying this is a symbol that we fight as equal leaf ninjas.” Still, Sasuke didn’t wear it and refused to see Naruto as his equal.

In their next battle, after Naruto explained why he’d go as far for Sasuke, Sasuke put his headband on. Naruto asked ‘if your breaking those bond then why put your headband on’? Sasuke answered, “I will acknowledge that you are strong.” and that’s when he made it a sign of accepting Naruto as his equal.

By the end of that battle, Sasuke’s headband got scratched -turning it to the sign of a missing-nin - then it fell off. Sasuke didn’t take it with him. He left it there, which symbolised his desire to leave Konoha and break all ties with everyone including Naruto.

The headband stayed with Naruto for years. Him holding on to it symbolized the fact that he never give up on Sasuke. That he always had hope.

In their last battle, there was a scene that actully links to this. In the past, Sasuke teased Naruto twice about how he’ll never be able to lay a finger on his forehead. In that last battle, there was a moment where Naruto deliberately aim his hit at Sasuke’s forehead,

It’s as if he’s saying, “I am your equal.”

Anyway, after that last battle, Naruto giving the forehead protector back to Sasuke was like saying that yes, he fulfilled the promise of bringing him back, didn’t go back on his words, never gave up on him and that he still sees him as Sasuke of the leaf.

However, Sasuke had a totally different view on this. He made his head protector a sign of their bond and their rivalry, rather than a sign that he belongs to Konoha. We don’t see him wear it, he only keeps it with him, so there is your proof. If he was proud to be a ninja of the leaf then he’ll wear the damn thing.

According to Boruto movie, Sasuke’s headband symbolises the true shinobi. One who endures and never gives up. So it has nothing to do with being a Konoha ninja, rather, It’s about the soul of the shinobi who’s carrying it, which actually links to Naruto’s determination.

In short: Sasuke’s headband is a symbol of SNS love bond. That’s why Kishimoto gave it a moment of its own.
