What is the proper procedure for washing hands?

The proper procedure for washing hands is to first wet the hands with clean, running water, which helps to remove dirt and micro-organisms. Next, lathering with soap is essential; it helps to create a barrier that lifts dirt, grease, and germs from the hands. Following the lathering, scrubbing is vital as this step involves rubbing the hands together and making sure to clean all surfaces, including between the fingers and under the nails, for at least 20 seconds. After scrubbing, rinsing with clean water removes the soap and the loosened dirt and germs. Lastly, drying the hands, preferably with a clean towel or air dryer, is important to avoid re-contamination.

This sequence is critical in maintaining hygiene, especially in settings like cosmetology where cleanliness is paramount. Other options may misplace crucial steps in the handwashing process, which can lead to ineffectiveness in removing harmful pathogens.
