Squid Game: 12 Hidden Details You Definitely Missed

5. Gi-Hun's Red Hair

Though many were baffled and shocked by Gi-Hun's choice of new hair, with its bold, almost cartoonish red, there was certainly more than one narrative reason for it.

The director pointed out that Gi-Hun's new hair was in part due to him wanting to have a huge change, show that he could never go back to his old self. It was, according to the director, something Gi-Hun would have never done before, showing just how much he'd changed after experiencing the games and his many losses. After losing his best friend, the people he'd come to trust in the game, as well as his own mother, there was no way the Gi-Hun from the beginning of the series would have survived to the end. And he didn't.

The colour of red also represents his rage, and how it would drive him to act against the Squid Game's leadership with his newfound wealth, power, and drive. It's in stark contrast to his paralysing grief, the year he spent destitute despite having access to immense riches.

Now that a fire has been lit under him, Gi-Hun's ready to fight, red hair and all.
