Who Is Required to Wear a Hair Restraint While Working?

A hair restraint is personal protective equipment, such as a cap, hairnet, or beard cover, designed to contain an employee’s hair. These devices serve two main purposes: maintaining hygiene and product integrity by preventing hair shedding, and ensuring worker safety by keeping hair away from hazardous equipment. The requirement to wear a hair restraint is determined by the specific risks present in a given work environment, established through regulatory oversight and industry standards.

The Legal Basis for Workplace Hair Protection

The authority for mandating hair restraints stems primarily from two federal agencies: the Food and Drug Administration (FDA) and the Occupational Safety and Health Administration (OSHA). The FDA sets hygiene standards, primarily through the Food Code, which is adopted by state and local jurisdictions to regulate food service and retail. This code establishes requirements for sanitary conditions. OSHA focuses on physical safety hazards, enforcing standards for personal protective equipment to prevent entanglement injuries around dangerous machinery. The determination of who must wear hair protection depends on which set of regulations applies to the employee’s role and environment.

Mandatory Requirements in Food Handling and Preparation

The most common requirement for hair restraints is in the food industry, where mandates prevent contamination. The FDA Food Code requires that food employees wear restraints that effectively keep hair from contacting exposed food, clean equipment, utensils, and linens. This applies to any employee whose duties involve direct contact with food or food-contact surfaces, regardless of hair length.

The scope of this rule includes cooks, chefs, and back-of-house staff like dishwashers who handle surfaces and utensils that will later touch food. Hair harbors microorganisms, posing a biological contamination risk if present in food or on preparation surfaces. The restraint also deters employees from touching their hair, which transfers pathogens to their hands and subsequently to food.

The restraint must contain all hair, including bangs and the hair at the nape of the neck, ensuring no contact is possible. Employees such as servers who only handle packaged food, hosts, and counter staff with minimal risk of contaminating exposed items are typically exempted from the full requirement. However, long hair must still be secured, such as in a ponytail, to prevent it from dangling into food or beverages during service.

Industrial and Manufacturing Compliance Needs

Hair restraint requirements outside of the food industry are driven by concerns over product purity or worker safety.

Product Contamination Control

In settings where the manufactured product must remain pristine, hair restraints serve as a component of contamination control, often using specialized garments. This applies to cleanrooms used in electronics assembly, pharmaceutical manufacturing, and medical device production. Hair is a source of particulates, skin flakes, and oils that can compromise sensitive products. Employees in these areas often wear low-lint bouffant caps or hoods designed to capture microscopic particles that could degrade product performance or purity.

Machinery and Safety Risks

A distinct set of requirements is enforced by OSHA to protect workers operating near moving parts, where the risk is physical injury rather than contamination. Employees working with rotating equipment, belts, chains, or other parts that could snag loose material must restrain their hair to prevent entanglement. Entanglement can lead to injuries such as scalping or being pulled into the machine. Employers must ensure employees cover and protect long hair with a cap, hairnet, or similar device to eliminate this hazard.

Sterile Environments and Healthcare Settings

In healthcare and related fields, hair restraints are worn to maintain an aseptic environment and protect the patient from microbial exposure. This mandate is common for surgical teams, including surgeons, nurses, and technicians, who must wear surgical caps that cover all hair before entering the operating room. The goal is to prevent the shedding of hair, skin cells, and associated bacteria that could cause a surgical site infection.

Personnel in compounding pharmacies and laboratories that handle sensitive biological samples are also required to use hair restraints. This requirement prevents biological contamination from compromising sterile equipment, patient medications, or experimental results. The use of sterile, disposable head coverings is standard practice to ensure the integrity of the sterile field and patient safety.

Defining Acceptable Hair and Beard Restraints

An effective hair restraint fully contains all hair and is designed for the specific risks of the work environment. Common devices include disposable hairnets made of fine mesh nylon, bouffant caps, and fabric chef hats or surgical caps. In food service, a hat or bandana may be acceptable, but only if worn over a hairnet to ensure complete containment of loose strands.

The requirement for hair containment extends to facial hair when it poses a risk of contamination. A beard net or snood is mandatory in food preparation and sterile environments if the facial hair is long enough to fall onto food, equipment, or into the sterile field. These restraints must be worn securely to prevent hair from escaping and introducing particulates or bacteria into the workspace.
