The popularity of gel manicures has raised concerns about the potential for bacterial growth under the nail polish. Studies have shown that all nail types, including natural nails, nails with standard polish, and gel nails, become contaminated with bacteria over time. However, gel nails have been found to retain the most bacteria even after cleaning with hand sanitiser or soap and water. This has led to concerns about the use of gel nails, especially in healthcare settings, where hand hygiene is crucial for preventing the spread of infections. While the exact mechanisms are not yet fully understood, the durability of gel manicures and the creation of crevices as nails grow out may contribute to the difficulty of sanitising gel-polished nails effectively.

Gel nails may be harder to clean with alcohol hand gel
A 2018 study found that gel manicures might be more challenging to clean with alcohol hand gel. The study authors suggest that as the nail grows, the nail outgrowth associated with gel polish may create crevices that make sanitising nails more difficult. This is supported by a 2020 study, which found that artificial and gel manicures correlate with "higher numbers and more species of microbes than bare nails".
The durability of gel manicures also poses a problem for infection control. As the gel manicure grows out with the nail, the intact polish can peel up, creating a gap for bacterial entry. This is not a new concern. A 34-year-old comparative study in the "American Journal of Infection Control" found that even after hand washing, artificial nails harboured higher counts of bacteria responsible for hospital-acquired infections.
The CDC recommends that healthcare workers avoid artificial nails, and the World Health Organization prohibits artificial nails and extenders for all healthcare workers.

All nail types become contaminated over time
The study also revealed that gel nails retained the most bacteria after cleaning with alcohol hand gel. The authors suggest that as the nail grows, the intact gel polish may lift, creating crevices that make it challenging to sanitise the nails effectively. This finding is consistent with a 2020 study, which reported that artificial and gel manicures were associated with "higher numbers and more species of microbes than bare nails."
The difficulty in cleaning gel nails has also been noted in other studies. One study found that while hand hygiene with alcohol hand gel reduced bacteria on natural nails and nails with standard polish, it did not significantly decrease bacteria on gel nails. Similarly, a 2018 study by Wałaszek et al. showed that hand disinfection was effective in reducing bacterial counts on natural nails and nails with standard polish but not on gel nails.
The presence of bacteria on nails is a concern, especially for healthcare workers who are in close contact with patients. The Centers for Disease Control and Prevention (CDC) advises against artificial nails for healthcare workers due to the risk of bacterial spread, and the World Health Organization (WHO) prohibits artificial nails and extenders for all healthcare workers.
To minimise the risk of bacterial contamination, the CDC recommends keeping natural nails short, preferably less than 1/4 inch in length. Additionally, proper hand hygiene practices, including regular handwashing and the use of alcohol-based hand sanitisers, can help reduce the bacterial burden on the hands and nails.

Gel nails may be a breeding ground for bacteria
The difficulty in effectively cleaning gel nails is another factor that contributes to their potential for harbouring bacteria. Alcohol-based hand sanitizers, which are commonly used for hand hygiene in healthcare settings, have been found to be less effective in reducing bacteria on gel-manicured nails compared to natural or standard polished nails. This is a significant concern as it increases the risk of bacterial transmission, especially in healthcare environments where maintaining proper hand hygiene is crucial for patient safety.
One study published in the American Journal of Infection Control evaluated the bacterial contamination of gel nails, standard nail polish, and natural nails on healthcare workers' hands. The researchers found that while all nail types became contaminated over time, gel nails retained the highest levels of bacteria even after cleaning. This finding highlights the increased risk of bacterial growth associated with gel manicures.
Furthermore, the durability of gel manicures can also contribute to the challenge of maintaining proper hand hygiene. As gel manicures can last for extended periods without chipping, the prolonged presence of the polish can create a favourable environment for bacterial growth. The crevices and gaps that form as the natural nail grows out provide additional spaces for bacteria to inhabit and multiply, making it challenging to achieve effective sanitization.
The implications of these findings are significant, especially in the healthcare industry. The Centers for Disease Control and Prevention (CDC) and the World Health Organization (WHO) have guidelines and recommendations regarding hand hygiene and the use of artificial nails in healthcare settings. While the guidelines aim to minimize the risk of bacterial transmission, the presence of gel nails or other artificial enhancements can hinder the effectiveness of hand hygiene practices and potentially compromise patient safety. Therefore, it is essential to consider the potential risks associated with gel nails and prioritize proper hand hygiene practices to mitigate the spread of bacteria.

Gel manicures and artificial nails are discouraged in healthcare settings
Artificial nails, including acrylics and gels, have been found to harbor more bacteria than natural nails. This is likely due to various factors, including hand hygiene practices, occupation, nail length, and other variables. Longer nails, in particular, provide more surface area for bacteria to adhere to and can be more challenging to clean effectively.
Studies have shown that gel nails may be more difficult to clean using alcohol-based hand sanitizer, which is commonly used for hand hygiene between patient contact. Alcohol hand gel has been found to reduce bacteria on natural nails and nails with standard polish but not on gel-manicured nails. This is a concern as it can potentially lead to the spread of bacteria and infections in healthcare settings.
To ensure patient safety and maintain proper hand hygiene, healthcare professionals are advised to keep their nails short, avoid artificial nails and gel manicures, and practice good hand hygiene. Some healthcare facilities have expanded their guidelines to prohibit artificial nails and gel manicures for all direct care providers. While modern nail technologies like gel manicures offer long-lasting and attractive options, they may not be suitable for healthcare settings due to the potential risk of bacterial contamination.

Natural nails are best kept short to prevent bacterial spread
Natural nails are the best option for preventing the spread of bacteria, and keeping them short further reduces the risk of bacterial contamination.
Nails, whether natural, polished, or artificial, can all become contaminated with bacteria over time. However, studies have shown that acrylic nails and nail polish tend to harbor far more bacteria than natural nails. This is because bacteria can become trapped beneath the surface of the polish or artificial nail, and are then more difficult to remove. Natural nails, on the other hand, are more easily cleaned, and keeping them short reduces the surface area where bacteria can accumulate.
In a healthcare setting, the hands of healthcare workers (HCWs) can become progressively colonized with normal flora and potential pathogens. As a result, health care-associated infections are a major problem for patient safety. For this reason, acrylic nails are not recommended for HCWs. While the data on gel nails is less clear, some studies suggest that they may be more difficult to clean using alcohol hand gel, and therefore may also pose a risk to patient safety.
Overall, natural nails kept short are the best option for preventing the spread of bacteria, especially in a healthcare setting.
