How old do you have to be to get a scaffold piercing in washington?

i just need to know the age limit with parental permission?

I'm pretty sure it's 16-17 with parental permission. I suggest looking up some of the shops in your area and seeing what they say. There usually isn't a set rule for it, every shop is different. Like some shops may refuse seeing, say, a 14 year old, whereas another shop might do it with the parent's permission. Then of course, once you hit 18, you can do whatever you want, lol.
