I found it neat how Finn has hair that is beautiful both in universe and out but always wears his hat all the time anyway, boy don't care about looking nice just loves his hat.
I prefer massively long hair Finn but all Finn hair is nice, even that weird, short Bobby Hill look he had that one time is serviceable.
