Tattoo Is It Illegal To Tattoo A Minor Without Profit?

Is it illegal to tattoo a minor without profit? - tattoo

A friend of mine wants a tattoo and knew that I wanted a tattoo, and offered to give me one for free. My parents are with him well, was his only rule that he would sign anything and if I have a legal way around the paperwork that it does not matter what I do not see with my body. So it would be legal to me a tattoo? I want to help and I want to take a tattoo, but do not want to cause any problem.
