The hospital I worked at didn't care about excess rings, if hair was up or down, dangle earrings, dark or trendy nail polish anything went.
I have an office job now of clinical review. We even have dress down Fridays and again they don't care for the most part what you wear within reason.
I just hear there are places that are strict on having hair up and things like no nail polish or if you do only neutrals etc...
So besides wearing scrubs
(bc the place I'm looking at has a set scrub they wear but I don't know anything else) do they have policies wear you work how you must look?
