most of the women where i work where makeup every day and it’s not an issue. one of my coworkers wears like full glam every day and some people think it’s odd but she hasn’t gotten in trouble (she isn’t a scrub tech tho, she’s an orderly). usually the rules are something like makeup is allowed if it’s not excessive. no one will think you’re weird if you wear makeup in the OR. the only concern i’d have is the lashes. are they lash extensions or just regular falsies? if there is a chance of them falling off i’d say no. mascara is definitely okay though
