A head cover is a protective garment designed to shield the hair, scalp, and sometimes the neck from contaminants, pollutants, or hazardous substances. Commonly used in medical, laboratory, and industrial settings, head covers can include surgical caps, disposable bouffant caps, or hooded garments. They help maintain hygiene and prevent the spread of contaminants by keeping hair secure and reducing the risk of contamination from the wearer's head.
