Which form of hair removal requires an electrical device?

Epilation refers to the hair removal method that involves removing the entire hair from the follicle, and it can be achieved through various techniques, including the use of electrical devices. Specifically, epilation devices, often called epilators, use a rotating set of tweezers or similar mechanisms to grasp multiple hairs simultaneously and pull them out at the root. This method provides longer-lasting results compared to shaving or waxing, as it removes the hair entirely instead of just cutting it at the skin’s surface.

Waxing and threading, while effective for hair removal, do not require an electrical device. Waxing involves applying a warm or cold wax to the skin and then removing it along with the hair, utilizing the adhesive properties of the wax. Threading employs a twisted thread that catches and pulls the hair out from the follicle without the need for any machinery. Shaving simply cuts the hair at the skin’s surface with a razor and does not remove hair from the follicle.

This distinction makes epilation the correct answer, as it specifically encompasses methods that utilize electrical devices to achieve its hair removal effects.
