Are Reusable Scrub Caps Allowed in NHS Theatres?

Yes. Reusable cloth scrub caps are permitted in NHS theatres, provided they are clean, laundered to the correct standard and comply with your local trust's uniform and infection-control policy. There is no national NHS ban on reusable headwear, and the available evidence shows properly laundered cloth caps perform at least as well as disposables.

What NHS England's national workwear guidance says

NHS England's workwear guidance treats scrub caps as a standard part of theatre attire. As the guidance states:

"Scrub caps must be worn by all theatre staff during procedures to prevent hair from falling into the sterile field."

The guidance focuses on the outcome — hair contained, the cap clean — rather than mandating a single-use material. That is the key point for anyone told reusables are "not allowed": the national guidance does not require disposable caps. It requires caps that are worn correctly and laundered properly.

On laundering, the guidance (section 5.2, "Washing uniforms and workwear") draws on scientific testing and expert opinion and concludes:

• there is little effective difference between domestic and commercial laundering in terms of removing micro-organisms from uniforms and workwear;
• washing with detergents at 30°C will remove most Gram-positive micro-organisms, including MRSA;
• a ten-minute wash at 60°C is sufficient to remove almost all micro-organisms — in tests, only 0.1% of Clostridioides difficile spores remained, a level microbiologists advised is not a cause for concern.

In short: the national guidance explicitly accepts home laundering as effective, which is what makes reusable caps practical for individual staff.

Trust-by-trust variation — and how to check your local policy

National guidance sets the framework, but each NHS trust writes its own theatre dress and infection-control policy. That is why one hospital welcomes personalised cloth caps while another, a few miles away, still defaults to disposable bouffants. The difference is almost always local policy, not national rules.

Before you switch, check three things with your local team:

• Your trust's theatre dress / uniform policy — ask your theatre manager or infection-prevention team for the current document.
• The laundering requirement — confirm whether home laundering at 60°C is accepted (it usually is, in line with the national guidance above) or whether caps must go through hospital laundry.
• Any colour-coding system — some trusts use cap colour to signal role or department, so check before ordering.

Washing requirements

Washing at a minimum of 60°C is the standard advice for scrub caps. At this temperature a short wash cycle removes almost all micro-organisms, and our cotton caps are built to withstand it — they can also tolerate commercial drying temperatures of over 180°C if your trust uses a professional laundry service.

Practical points that keep reusable caps compliant:

• Wash at a minimum of 60°C after each use.
• Keep dirty caps separate from clean ones — a dedicated laundry bag prevents cross-contamination in transit.
• Use proper detergent and a full drying cycle; agitation, rinsing and temperature all contribute to removing micro-organisms.

The evidence: cloth performs at least as well as disposable

The case against reusables usually rests on an assumption that single-use means safer. The published evidence does not support that.

• A 2024 rapid review by Nyima and colleagues (Nyima et al., 2024) found no evidence that disposable bouffant caps reduce surgical site infection rates compared with properly laundered cloth caps, while cloth caps showed clear advantages in team communication, cost and environmental impact.
• A 2026 study of 107 theatre personnel by Hughes and colleagues (Hughes et al., 2026) measured higher bacterial counts on some cloth caps — but the researchers' own conclusion was that the issue is laundering standards, not the fabric. They called for proper sterilisation of cloth caps rather than abandoning reusables. The takeaway for theatre teams: a clean, correctly washed cloth cap is the goal, and that is achievable.

Taken together, the research supports a simple position: reusable caps are safe when laundered to standard, and they bring benefits disposables cannot — named, personalised caps improve communication in theatre, and reusables cut waste and ongoing cost.

What to show your theatre manager

If you need to make the case locally, bring this short checklist to the conversation:

• National guidance allows it. NHS England's workwear guidance requires caps that contain hair and are laundered properly — not disposable-only.
• Laundering is covered. The same guidance confirms a 60°C wash removes almost all micro-organisms, and accepts home laundering as effective.
• The evidence is on your side. Nyima et al. (2024) found no SSI benefit from disposables; Hughes et al. (2026) confirmed the variable is laundering, not material.
• You have a laundering plan. Wash at 60°C after each use, separate clean and dirty caps, and follow any local colour-coding.
• Confirm local policy. Ask the infection-prevention team to confirm reusables are accepted under the current theatre dress policy.

Next steps

Reusable cloth scrub caps are allowed in NHS theatres when they are clean, correctly laundered and in line with local policy — and the evidence shows they perform at least as well as disposables. The simplest way to trial them on your unit is to order a sample first.
