Long hair, short hair, bolt head, spiked hair, matted hair, any type of strange hair, even the word "strange" is strange here, isn't it? If you want to do something special with your body, whether it is the hair, whether you want tattoos, whether you want rings through your nose and rings on your toes and bones through your nose, it's usually to draw attention from others. If so, that would appear to be an unbeneficial intention. "I want to be seen, I want fame, I want praise, etc."
