Why Hairnets Matter in the Food and Pharmaceutical Industries: A Regulation and Procurement Guide

Hair falling into a product isn't just a matter of appearance. In the food industry, hair can trigger complaints, product recalls, or audit findings. In pharma, an operator's hair and particles can raise the risk of contamination to materials, process areas, and the product itself.

Because of that, a food-industry hairnet and pharmaceutical headwear need to be treated as part of a hygiene system, not a uniform accessory. This article covers how hairnets relate to GHP, HACCP, CPPOB, and CPOB, along with the specifications procurement teams need to check.

Why Does Hair Pose a Contamination Risk?

Human hair can naturally come loose as a worker moves, bends down, puts on or removes PPE, and touches their head. Beyond individual strands, the head area can also shed skin flakes, dust, oil, and other particles.

In a production environment, the risk can take the form of a physical hazard, microbiological contamination, an audit nonconformance, a consumer complaint, or a process disruption.

A hairnet doesn't work on its own. Its effectiveness depends on how it's worn, hair coverage, hand hygiene, uniform control, personnel flow, and discipline in replacing the product.

Hairnets Within a HACCP System

HACCP, or Hazard Analysis and Critical Control Point, is a science-based system for identifying hazards, setting controls, and preventing food-safety problems. Codex explains that HACCP focuses on prevention, not just testing the finished product.

That said, there's no single "HACCP hairnet certificate" that automatically makes a hairnet meet every plant's needs. A hairnet is generally placed as part of Good Hygiene Practices, sanitation standard operating procedures, or a prerequisite program that supports the HACCP system.

The Codex General Principles of Food Hygiene state that food workers need to maintain personal cleanliness and, where appropriate, use protective clothing and head coverings. That reference is available through the Codex General Principles of Food Hygiene and HACCP.

A hairnet as a physical-hazard control

In a hazard analysis, a company can identify hair as a potential foreign-object risk. Controls can include:

• using a hairnet;
• a beard cover for workers with facial hair;
• a ban on combing hair in production areas;
• inspection before entry;
• rules for replacing headwear;
• restricted access to certain zones;
• personal hygiene training.

This kind of control is usually not a Critical Control Point. A hairnet is more often part of the baseline program that needs to run consistently before a HACCP system can be applied effectively.

What does an auditor actually assess?

An auditor doesn't just check whether a hairnet exists. They can assess hair coverage, how long it's been worn, habits around touching the head, storage, beard-cover availability, visitor compliance, and training and inspection records.

In other words, a "HACCP hairnet standard" is better understood as how correctly hairnets are used within a documented hygiene system.

"A good hairnet isn't just available at the production entrance. The product needs to match the risk, be easy to wear correctly, and be backed by an SOP that keeps all the hair covered throughout the shift." — Fit-U Team

Hairnet References for Indonesia's Food Industry

For processed food manufacturers, hygiene implementation relates to Good Manufacturing Practice for Processed Food, or CPPOB. Indonesia's food and drug agency, BPOM, sets the procedure for issuing a CPPOB implementation permit through BPOM Regulation No. 22 of 2021, which was still in effect at the time this article was written.

CPPOB covers facilities, sanitation, process, storage, documentation, training, and employee hygiene.

A hairnet doesn't replace personal hygiene

Workers still need to wash their hands, wear clean clothing, avoid risky jewelry, report illness, follow the area's flow, and replace damaged or contaminated PPE.

A hairnet only controls part of the risk coming from the head and hair.

Use based on zone

A plant can have low-, medium-, and high-risk zones. Head-covering needs can differ based on:

• whether the product is open or enclosed;
• ready-to-eat product;
• hot or cold processing;
• exposure after a kill step;
• air cleanliness;
• cross-contamination risk from raw material;
• how much contact the operator has with the product.

In a zone packaging an enclosed product, the risk is different from an area processing ready-to-eat food. Procurement shouldn't set a single specification without input from Quality Assurance, Food Safety, and production.

The Role of Hairnets in the Pharmaceutical Industry

In the pharmaceutical industry, people are one of the main sources of particles and microorganisms in a production room. Headwear is used to reduce the shedding of hair and particles from the scalp.

The applicable standard in Indonesia refers to BPOM Regulation No. 7 of 2024 on CPOB Standards, which was amended by BPOM Regulation No. 7 of 2025.

A pharmaceutical hairnet needs to match the area's classification

Not every pharma area has the same needs. A packaging-material warehouse, weighing area, non-sterile production, laboratory, and sterile cleanroom can each call for a different clothing combination.

In some areas, a standalone hairnet can be used. In areas with tighter control, headwear can become part of a hood or coverall designed to minimize particle shedding.

Because of that, a pharmaceutical hairnet shouldn't be chosen based on color, thickness, or price alone. The QA team needs to determine whether the product:

• is used as primary headwear;
• is worn under a hood;
• suits a non-sterile area;
• meets a low-lint requirement;
• is compatible with masks and coveralls;
• is single-use or has a validated laundering procedure;
• fits the gowning sequence.

A cleanroom hairnet isn't a procurement decision alone

Buyers need to request a User Requirement Specification from the user department. For critical areas, the decision can involve QA, production, microbiology, EHS, and validation.

Specifications can cover material, fiber shedding, size, elastic, hair coverage, packaging, bioburden if required, sterile status, sterilization method, and supplier documentation.

Not every facility needs a sterile hairnet. Conversely, using a regular hairnet in an area that requires sterile garments can be a serious nonconformance.

Food Hairnets vs. Pharmaceutical Hairnets

This table is general. Actual requirements need to follow the facility's own risk assessment and procedure.

Hairnet Specifications Worth Checking

Non-woven material

A disposable hairnet is generally made from a non-woven material like spunbond. The material needs to be light enough for a whole shift but not so thin it tears easily when put on.

Buyers need to check material consistency, not just the weight printed on the spec sheet. A product that's too thin can fail, while material that's too heavy can increase heat discomfort.

Elastic

The elastic needs to hold the hairnet in place without pressing on the head excessively. Loose elastic lets hair escape easily, while elastic that's too tight causes discomfort and can push workers to modify how they wear it.

Consider:

• head-size range;
• shift duration;
• use alongside a helmet or hood;
• elastic material;
• potential latex sensitivity;
• attachment strength.

Size and hair capacity

Workers have hair of different length and volume. A single small size can fail to contain long or thick hair.

For a diverse workforce, a company can offer more than one size and test the product across a range of hair types and headwear combinations.

Single- vs. double-elastic design

A single-elastic hairnet has one elastic line, while a double-elastic design can provide extra hold in some designs. The best choice depends on the area and how it's used.

Don't assume double elastic is always safer. The product still needs to fully cover the hair and stay comfortable throughout the activity.

Color for zoning

Color can help identify a department, visitors, technicians, a raw-material area, finished product, or a high-care zone.

That said, a color system needs to be documented and easy to understand. Too many colors can confuse workers and increase the risk of entering the wrong area.

Hairnet vs. Haircap: What's the Difference?

The terms hairnet and haircap are often used interchangeably, but the product shapes can differ.

A hairnet is usually a stretchy, non-woven net shape that expands to follow the hair. This product is lightweight and practical for high-volume use.

A haircap can have a more structured shape or different coverage, depending on the design. Some facilities choose a haircap when they need a more stable covering or a specific uniform look.

The choice should be based on hair coverage, stability, compatibility with other PPE, area risk, duration, and documentation.

The product name alone isn't enough. Buyers need to request a sample and the actual specification.

The SOP for Wearing a Hairnet Correctly

The sequence can differ between companies, but the general principles include:

1. Remove jewelry and personal items.
2. Tidy up or tie back long hair.
3. Wash and dry your hands per procedure.
4. Take a hairnet without touching much else.
5. Fully open the hairnet.
6. Pull it on from front to back over the hair.
7. Make sure bangs, side hair, and hair at the nape of the neck are covered.
8. Put on a beard cover if required.
9. Continue the gowning sequence for the zone.
10. Check via a mirror or a verifying staff member.

A hairnet shouldn't be worn over only half the head or left dangling around the neck. If it comes loose, tears, falls on the floor, or gets contaminated, it needs to be replaced per the SOP.

Common Mistakes That Turn Up as Audit Findings

Common nonconformances include:

• bangs sticking out of the hairnet;
• long hair left untied;
• a hairnet being reused;
• a worker touching their head after hand hygiene;
• a visitor not following gowning;
• no beard cover available;
• an open, dusty hairnet dispenser;
• a color that doesn't match the zone;
• stock running out at the entrance;
• a hairnet taken outside and then reused;
• a supplier specification changing with no evaluation.

These issues show that compliance needs supply, training, supervision, and documentation working together.

Hairnet Procurement Checklist

Before buying, confirm:

• intended use and zone;
• non-woven material;
• size and hair capacity;
• elastic type;
• latex-free status if needed;
• single- or double-elastic design;
• color;
• sterile or non-sterile;
• low-lint level;
• contents per bag and carton;
• batch identity;
• shelf life;
• packaging condition;
• specification documentation;
• a sample for trial;
• the supplier's ability to maintain stock;
• procedure for handling defective product.

For food or pharmaceutical production, run a trial across one or several shifts. Measure the defect rate, user complaints, hair escaping, and ease of use.

FAQ About Industrial Hairnets

Does HACCP require a specific hairnet brand or type?

No. HACCP requires a company to identify and control hazards. The hairnet type is determined through a risk assessment, GHP, and the facility's own SOP.

Is a hairnet mandatory in every area of a food plant?

The need follows the risk and the zoning rules. An area with open product generally needs tighter control than an administrative area.

Does a pharmaceutical hairnet need to be sterile?

Not always. Sterile or non-sterile status depends on the area classification, process, and the facility's CPOB SOP.

Can a hairnet be reused?

A single-use hairnet shouldn't be reused. A reusable product needs a proper washing, inspection, and control procedure.

What's the difference between a hairnet and a beard cover?

A hairnet covers head hair, while a beard cover contains hair on a beard or mustache. Both can be required together.

Conclusion

A hairnet is a simple control with a large operational impact. In the food industry, it helps prevent hair from becoming a foreign object and supports GHP, CPPOB, and the HACCP prerequisite program. In pharma, a hairnet is part of a gowning strategy to reduce the shedding of particles and microorganisms from the operator.

The purchase decision shouldn't stop at the price per bag. Procurement needs to connect material, size, elastic, packaging, color, and sterile status to the zone and process risk. A hairnet that's cheap but tears easily, is too small, or is inconsistent can increase waste and audit findings. Conversely, the right product helps a company maintain hygiene discipline and inspection readiness.
