Everyone in the operating theatre has to wear a special hat so that hairs or bacteria from their hair don’t end up in your wound. There are lots of different kinds of scrub caps. They come in different colours, and some of them look almost like a helmet with a built-in scarf. The kind of caps you’ll see our staff wearing will vary depending on which ones they like best, and on the different rules that say which caps they have to wear for various operations. Which cap do you think looks the best?
