Bouffants are loose-fitting headwear that are worn over hair to prevent loose hair from falling into food, pharmaceuticals, and other substances to help ensure a clean and hygienic work area. They are made of breathable woven fabric and have an elastic band to keep them in place. Bouffants have a tighter weave than hairnets, making them easier to see and lowering the risk of contamination. They are worn in food processing applications and medical settings.
