Regular hand washing is regarded as the best method for preventing the spread of germs due to its effectiveness in physically removing contaminants from the hands. When performed correctly, it involves scrubbing with soap and water for at least 20 seconds, which helps eliminate not only germs but also dirt and other pathogens that hand sanitizers might not fully address.

While using hand sanitizers is a suitable alternative when soap and water are unavailable, it may not be as effective on visibly dirty or greasy hands. Wearing gloves provides a barrier but does not replace the need for good hand hygiene, as gloves can become contaminated themselves. Similarly, while using disinfectants is essential for cleaning surfaces and tools in a salon environment, it does not address germs present on hands. Thus, regular hand washing stands out as the most comprehensive and reliable approach to maintaining hand hygiene and preventing the transmission of germs in both personal and professional settings.
