How to become an alternative model
Don't change yourself for the wrong reasons.
You should not change your looks or personality to fit into a stereotype. Alternative models often have piercings and tattoos, but you should not alter your appearance just to become a model.
You should change hair or acquire body art because you desire them, and/or because they are meaningful to you. Alternative models typically look alternative on a daily basis, rather than dressing up for photo shoots.
