Hair caps are used in various settings, such as "food processing factories," "precision equipment manufacturing plants," "laboratories," and "medical facilities." Also known as "hygiene caps," they are an essential tool in a variety of workplaces, not only preventing hair and dirt attached to hair from falling but also protecting workers from splashes of liquids and bacteria. *Disposable hair caps must be discarded after each use. Reusing them increases the risk of secondary contamination.*
