By only feeling “normal” with freshly trimmed hair then the character would feel “weird” when not having it and should suffer a moral penalty, they would also run out of hair rather quickly cutting it ever few days.
As a person who has had long and short hair the only time I cut the long hair is when I wanted it shorter, trimming a 1/4" off long hair doesn’t do much, and there was no feeling of “normalcy” that would only apply if your character had a very specific interpretation of what normal is. Guess they could code in hair OCD, must have hair exactly between a certain length or suffers penalties due to the mental hangup. I see how this might apply to someone obsessed with military haircuts, but that is an obsession most people don’t have.
The hair tie would get your long hair out of your eyes.
The question was already answered, and if a discussion on what is or is not “normal” for hair length is going to happen would fit better in non game talk.
But I’m now going to look into making a hair tie item that gives a mood boost, for those men and ladies who have long hair.
