Mayo Clinic employee appearance

Hello everyone,
I am new to Mayo Clinic! I did have a question regarding tattoos, piercings and hair colors. I have worked through Dove Health Care and Marshfield Clinic and I know both are very relaxed on these three topics. I guess I was wondering because I do have a few "appropriate" tattoos as well as a few discrete facial piercings (as discrete as on the face can be.) I also am one who likes to change my hair color often. Never have I had pink, blue, red etc. hair colors but I didn't know if there were specifics. Any information would be helpful!
Thank you!
