Students with scarring or sensitive skin must get a note from a campus doctor. Non-LDS students who wear beards as part of their faith must secure approval from a chaplain. Student actors in film or theater roles requiring facial hair must get a note from the theater department. After that, final permission comes from the honor code office.
