Epilation refers to several methods that remove hair at the root. Popular methods include waxing, tweezing, threading and mechanical devices. Most of these methods safely remove hair on the face; however, mechanical epilators that use hundreds of tiny tweezers or coiled metal to remove hair are not appropriate for the face; use these devices only on the forearms and legs to avoid injury, suggests ConsumerReports.org.
DermNet NZ lists waxing as the most effective method of epilation. Waxing removes hair from the root by entangling it in a thin layer of wax and pulling it free. While there is some discomfort associated with the procedure, waxing removes hair from large areas at once. Other forms of epilation remove one or a few hairs at a time, which takes longer and results in more discomfort.
Tweezers remove single or stray hairs one at a time. They work well for removing hair leftover from waxing or shaping eyebrows in between waxes. They are also ideal for those who are afraid to remove too much hair at one time. To tweeze, simply grasp the end of an individual hair with the tweezers, and pull it out quickly in the direction of the hair growth.
Threading, an ancient method of hair removal, removes hair from the face using only a stretch of cotton thread. In threading, a strand of twisted cotton thread rolls along the skin, removing hairs that get caught in the coils of the thread. The procedure causes less pain than waxing and tweezing, according to DermNet NZ.
Dermatologists have certain devices that remove hair from the root. Needle epilators destroy the hair root via an electrical current delivered by a small needle inserted into the hair follicle. After shocking the root, the technician removes the hair with a pair of tweezers. Electrolysis devices work similarly, and they are the only hair-removal devices that the FDA considers as permanent. Another method uses tweezer epilators. In this method, the technician grasps the hair with a pair of electrical tweezers. Electrical current passes through the tweezers and along the hair shaft in an effort to prevent future growth. The technician tweezes the hair immediately after the electrical shock.
