If you are below 18, your parents must sign a form. Otherwise, you are free to do what you want. This goes for all piercings.
Agreed, 18 and over, no problem, under, Parent permission is needed. I took my 16yr old for a belly piercing and I had to sign for her to get it. Plus the man "Rocky", who did it was amazing and had no problem answering questions and even volunteered information. It was great.
