What process involves the complete removal of hair from its follicle?

The process that involves the complete removal of hair from its follicle is known as epilation. This technique removes hair from the root, leading to longer-lasting results compared to methods that only affect the hair shaft. Epilation can be achieved through various methods, including waxing, tweezing, and using epilator devices, all of which extract the hair along with its follicle from beneath the skin.

In contrast, depilation refers to removing hair at the skin's surface, typically using shaving or chemical depilatories, which does not involve pulling hair from the follicle. Shaving simply cuts hair at the skin level, while trimming involves cutting hair to a shorter length without removing it from the follicle. Thus, each of these options describes a different method of hair removal, but only epilation results in the complete extraction of hair from its follicle.
