Eren: (spends like five minutes on his hair. Sometimes forgets to brush it)
Armin: (Armin's hair magically stays the same for some reason...)
Mikasa: (just brushes it)
Levi: (spends like two hours trying to make it absolutely perfect because he's fabulous and has to stay fabulous)
Hanji: (I wouldn't stick my hand in her hair if i were you. Levi's convinced that there are little animals raising a colony somewhere in there)
Erwin: (Erwin wears a wig. He doesn't want to admit it, but he's very bald. He spends more time styling the eyebrows anyway)
