It was getting ridiculous at this point

Luffys hair was down to his nape and almost covering his eyes, shaggy and unkempt as he hadn't gotten it cut in quite some time. He hated haircuts, king stuck in one place for too long made him fidget, and keeping him still to ensure that you wouldn't mess up was hell

You had been fighting with him for a bit now, barely even halfway done with brushing his hair to get all the tangles. Of course it was hurting him whenever you dragged the brush over his hair, it was all knotted!
