Why does Finn hide his hair adventure time?

Finn hides his hair in "Adventure Time" primarily because he is self-conscious about it. His short, messy hairstyle contrasts with the traditional heroic image he aspires to, and he often feels pressure to conform to societal ideals of appearance. By concealing his hair, he tries to maintain a sense of identity and confidence in his adventures. Ultimately, it reflects his growth and acceptance of himself throughout the series.
