A nurse cap is a cap worn by nurses or any other healthcare provider as part of their protective healthcare clothing. It prevents dust particles or micro-organisms on the operator’s hair or scalp from falling onto the sterile field or in the direction of the patient. The cap is made of non-woven fabric and offers an excellent fit on the operator’s head due to a single elastic band, which provides excellent cap stability. The cap ensures perspiration and does not irritate the operator’s scalp, even when worn for several hours a day. It is necessary to choose the correct size, and also to tie up the hair if it is too long, especially in the case of women.
