I had a headcanon idea to go along with redhead Good-Ending Saeran: He starts letting his natural hair grow out after deciding to no longer bleach it. With every haircut, there's less and less white, but it takes its time to go away. at some point there is only a bit of white left and it sinks in that it isn't going away fast enough. The white tips are too much of a reminder of the brainwashing at Mint Eye, and he has a moment where he suddenly can't stand it. In a hasty move to create distance from his past self, Saeran grabs scissors to get rid of every speck of bleached hair left. (I think it matches a bit of how Saeran is quick to act like everything is okay with himself after his own route, as if he can't quite admit things still aren't perfect because reflecting is so difficult.) The aftermath is a bit awkward,,,
