tattoo allergies

I have numerour allergies, and I finally have the courage to get a tattoo. Upon going to the tattoo shop, I asked about their ink and the composition of the ink. I was told the ink has sulfite, I am allergic to sulfur, sulfate and sulfites. I would like to know if there are any brands of inks that do not carry these chemicals. I really want a tattoo. Help a girl out, please, oh pretty please!!! Thanks for your time and trouble!!!!
