Key Takeaways
- Coverage is the real difference. A bouffant cap covers the ears, scalp and nape of the neck; a traditional skull cap typically leaves the ears and part of the nape exposed.
- This is a guideline conflict, not a settled rule. AORN’s full-coverage language has been revised and softened, while the American College of Surgeons accepts skull caps and says current evidence shows no link between hat type and infection (ACS Statement on OR Attire).
- The science does not separate the two. A University at Buffalo study of nearly 16,000 cases found switching from skull caps to bouffants did not reduce surgical site infections (Neurosurgery, 2018).
- Stock by role. Bouffant caps as the default for most OT staff; disposable skull caps as a documented option for surgeons using loupes or headlamps.
- For bulk supply, specify SBPP non-woven, size range and pack format, and match the choice to your facility’s adopted guideline.
In 2017, a surgeon-led campaign known as #BanTheBouffant pushed back against hospital policies that effectively required bouffant caps over the traditional skull cap. Years later the debate is still live, and peer-reviewed evidence has consistently failed to show that one cap type reduces surgical site infections (SSIs) more than the other. OT managers are left between an accreditation-driven policy on one side and surgical-team preference on the other. This guide compares both products on coverage, evidence, guideline compliance, comfort and bulk specification, so you can make an informed decision.
A surgeon cap, also called a skull cap or scrub cap, is a close-fitting, tie-back head cover worn in the operating theatre. It covers the crown and top of the head, but in its standard configuration leaves the lower ears, sideburns and nape of the neck partially or fully exposed.
Containing scalp hair and skin matters because organisms that colonise hair and skin can disperse into the sterile field, which is why head coverings are worn at all alongside surgical drapes used to protect the sterile OT field.
A bouffant cap is a loose, pleated circular cover held by an elasticised rim. Unlike the skull cap, a properly sized bouffant fully covers the ears, all scalp hair, sideburns and the nape of the neck in a single garment.
Dispowear manufactures bouffant caps in virgin SBPP across the common diameter range, with customisable colour and branding, for bulk OT supply.
This is a disagreement between professional bodies, not a settled regulatory mandate. AORN historically favoured full coverage but has since softened that language, while the ACS accepts skull caps and the evidence shows no SSI difference between the two.
The takeaway for OT managers: the science does not resolve this debate in favour of either cap. Compliance is driven primarily by your hospital’s adopted guideline and accreditation framework, not by a settled infection-control fact.
Strip away the guideline debate and compare the products on what matters to an OT manager.
| Attribute | Surgeon / skull cap | Bouffant cap |
|---|---|---|
| Coverage | Crown and top of scalp; ears/nape may be exposed | Full: ears, scalp, sideburns, nape |
| Stability under loupes/headlamps | Stays in place better | Prone to migration |
| Comfort, long procedures | Lighter; less heat retention | Elastic band can mark the forehead |
| High / voluminous hair | Not designed for it | Pleated design expands to fit |
| Full-coverage compliance | Partial (standard design) | Full |
| Typical disposable SBPP weight | Heavier, structured | Lighter, pleated |
| Cost per unit at scale | Slightly higher | Lower |
In practice: skull caps are consistently preferred by surgeons using loupes or headlamps, where bouffant migration is a documented complaint. Bouffant caps give full coverage with no special donning skill, which suits nurses and OT technicians, and the 21 inch or larger bouffant is the only option that properly contains long or voluminous hair.
There is no universal right answer. The correct head cover depends on your facility’s adopted guideline, the wearer’s role and hair volume. A practical framework:
On specification: bouffant in SBPP across the standard size range, lint-free and latex-free, in your OT colour code; surgeon cap in SBPP, tie-back or elastic, one size. These sit within the wider OT PPE checklist covering head covers, gowns and shoe covers.
A 2024 meta-analysis found reusable headwear matches disposables on SSI outcomes (J Hosp Infect, 2024). Reusable head covers may be appropriate where validated laundering systems are available. However, disposable SBPP caps remain the preferred choice for single-use environments, minimising cross-contamination risks and simplifying infection control.
For procurement teams sourcing a disposable bouffant cap or disposable surgeon cap at scale, the specification and supply chain matter as much as the design. Dispowear bouffant caps are built around the following features:
As a surgical cap manufacturer, Dispowear combines ISO 13485 quality systems, virgin SBPP, low-lint construction and latex-free materials with proven export capability and customisation options, so each hospital head cover meets both clinical and procurement requirements.
Bouffant caps provide full coverage; skull caps may leave the ears and nape exposed. The guidelines favour full coverage in principle, but the evidence shows no SSI difference between the two, so the decision is really about your facility’s adopted guideline, the wearer’s role and hair volume. Stock bouffants as the default and disposable surgeon caps as a documented option for surgeons with an equipment-based rationale.
Dispowear Protection manufactures disposable bouffant caps and surgeon caps using high-quality SBPP non-woven fabric under ISO 13485 quality systems. Available in multiple sizes, colours, and packaging formats, our head covers are designed for hospitals, operating theatres, cleanrooms, and medical device manufacturing facilities.

A scrub cap (surgeon or skull cap) is a close-fitting, tie-back cover that usually leaves the ears and nape exposed. A bouffant cap is a loose, pleated cover held by an elastic band that fully covers the ears, scalp and nape. The key difference is coverage completeness.
No. AORN’s guidance called for covering the hair and (in the 2015 edition) the ears, scalp, sideburns and nape, but it does not name the bouffant. AORN itself clarified it did not mandate bouffants, and the guideline has since been revised and softened.
No. Peer-reviewed evidence does not show that bouffants reduce surgical site infections more than skull caps. A University at Buffalo study found no reduction in SSIs after switching to bouffants, and a 2024 meta-analysis found no SSI difference between reusable and disposable headwear. The debate is a guideline conflict, not an evidence-based distinction.
The mid-range (around 21 inch) bouffant is the most commonly stocked size and fits most hair volumes. Stock smaller sizes for short or low-volume hair, and larger sizes for long or thick hair. Under-sizing is a compliance failure, because hair escaping the elastic perimeter defeats full coverage.
No. Disposable SBPP caps are single-use. Discard at the end of each procedure or on exiting the OT. Reuse risks bacterial transfer and elastic failure that reduces coverage. Reusable cloth options exist but require validated laundering after every use.
