Iron Age Tattoos and TRX tattoos both pierce noses of minors with parental consent in accordance with Missouri law. Neither location, nor any other tattoo parlor in St. Louis, states that it will tattoo a person under 16; although, Enigma tattoos and other parlors do not state a minimum age.
Some tattoos are still prohibited for minors regardless of parlor policy, including any neck, face and genital tattoos. Particular artists may choose to refrain from tattooing minors even with parental consent. Piercers are typically less-hesitant because the permanent change to the minor's body is less than that of a tattoo.
