Do medical masks work with beards? That question became the center of a public debate when Prabhjeet Gill, a student paramedic at Monash University in Australia, refused to shave his beard for religious reasons. As a Sikh, keeping facial hair is part of his faith. When Ambulance Victoria denied him a medical mask fitting due to concerns about sealing, Gill challenged the policy and won. But the incident raised a broader question: can people with beards safely wear medical masks?

Gill filed a complaint with the Australian Human Rights Commission, after which the ambulance service changed its policy. But does a medical mask really offer less protection with a beard? In this article, I explain the rules, research, and how men with beards can still ensure proper mask protection.
What studies say about medical masks and beards
The goal of a medical mask is simple: it must protect both the wearer and their surroundings from viruses and harmful particles spread through breathing. For this to work, the mask needs to form a tight seal around the face. Facial hair makes this difficult, which is why beards are often not allowed when medical masks are required.
Multiple studies have confirmed that facial hair significantly reduces a mask’s effectiveness. In a 2020 study, researchers tested the fit of P2 and N95 masks on 105 men. None of the men with full beards passed the fit test. Among clean-shaven participants, 47% achieved a safe seal. The U.S. National Institute for Occupational Safety and Health (NIOSH) also found that even two days’ worth of stubble can interfere with the mask’s performance.
The Singh Thattha technique: improving mask fit for bearded wearers
Gill was aware of the problem and came prepared with a solution: the Singh Thattha technique. He had even asked for permission to use it in advance.
This technique involves covering the beard with an elastic band before putting on the mask. Below are some visuals of how it works:
This method first gained attention during the pandemic, when a transplant surgeon in Manchester, UK, began promoting it. Research suggests it can be effective: in one study, 96.2% of men achieved a proper seal when using the Singh Thattha technique in combination with an FFP3 mask. The researchers also noted that higher-quality masks further increased the chances of success.
Still, not everyone agrees on its reliability. NIOSH, the U.S. National Institute for Occupational Safety and Health, continues to raise concerns. The study only involved 27 bearded participants, and the tightness of the elastic band varies from person to person. It’s also unclear how well the seal holds up when the wearer starts sweating during long shifts.
To address these issues, NIOSH is now partnering with the Sikh Coalition and various manufacturers to create standardized solutions. Until those are available, they advise against wearing medical masks with a beard.
Religious identity vs. safety: the debate around beards and masks
Although not all health organizations endorse the Singh Thattha method, Gill strongly disagreed with the rejection, especially since he had disclosed his intention to use the technique beforehand. He filed a formal complaint to challenge the decision.
“Like the turban, the beard is part of our identity. (…) We believe we should not remove hair from the body; we must leave it as God created us,” he told ABC News.
Before the commission issued a response, Ambulance Victoria reversed its policy. A spokesperson confirmed the launch of a new fit-testing process that allows religious, cultural, or medical exemptions for facial hair through the Singh Thattha method.
Although Gill was allowed to resume his studies, he didn’t consider the outcome a victory. “No one should have to fight a state government organization just to keep their religious identity,” he said.
Do medical masks work with beards in high-risk professions?
This issue goes beyond healthcare. The U.S. Air Force had banned beards for years, citing professional standards. However, rising criticism and medical concerns such as pseudofolliculitis barbae, a painful shaving condition, pushed the Air Force to grant exceptions for religious and medical reasons.
The aviation sector has faced similar challenges. Pilots and flight attendants must wear oxygen masks during emergencies, and for years, facial hair was not permitted due to sealing concerns. Fortunately, modern oxygen masks are now designed to seal properly, even with facial hair.
So, do medical masks work with beards in 2025?
Religious and medical freedom matter, but safety should always come first. If facial hair compromises a mask’s performance, then the safety of both the wearer and others is at risk. Until better alternatives are available, this might simply mean that some jobs are temporarily off-limits to people with beards.
That’s not always fair. But is it fair to endanger others when your mask doesn’t work?
