Body piercing laws fall under state legislation, which means each state sets their own rules for governing the service. Some states prohibit piercing of anyone under the age of 18, some allow body piercing for minors as long as parental consent is given and others have no piercing regulations set.
Body piercing has been a part of human culture for thousands of years. Piercings have played a part in determining status in various ancient cultures. In Ancient Egypt, pharaohs had their navels pierced and displayed them, but those of lower status would be put to death if displaying a navel piercing.
