Which of the following is true regarding ingrown hair?

The belief that electrologists must tweeze hair from the infected follicle reflects a common practice in managing ingrown hairs, particularly when they cause irritation or infection. When a hair becomes ingrown, it can lead to inflammation and sometimes infection if left untreated. Tweezing can help extract the hair from the follicle, potentially relieving discomfort and allowing the area to heal properly.

While it is crucial to be cautious when addressing ingrown hairs, especially in infected cases, removal may facilitate healing. Proper sanitization protocols must be followed to prevent further infection. However, not every professional agrees on the necessity of this action, as it depends on the specific circumstances of each case.

The other options address aspects of ingrown hair management that are not universally applicable. For example, leaving an infected follicle alone or assuming all ingrown hairs will resolve without intervention are not effective approaches in many situations. Similarly, while it may be tempting to tweeze hairs from infected areas, it is essential to consider the potential for exacerbating the infection or causing additional irritation.
