How old do you have to be to get a tattoo in Virginia with a parent consent?

The Virginia Code doesn't specify the minimum age. § 18.2-371.3. Tattooing or body piercing of minors. No person shall tattoo or perform body piercing for hire or consideration on a person less than eighteen years of age, knowing or having reason to believe such person is less than eighteen years of age except (i) in the presence of the person's parent or guardian, or (ii) when done by or under the supervision of a medical doctor, registered nurse or other medical services personnel licensed pursuant to Title 54.1 in the performance of their duties.
