Eyebrow threading is a form of epilation. The process removes the entire hair, including the root, rather than cutting it. It starts with cleaning the skin under and around the eyebrows with a gentle cleanser or quick wipe with alcohol to make sure the area is sterile, and it is easy to see the hairs.
A technician will hold a piece of thread between their hands, occasionally with one end in their teeth, and twist it. They’ll then hold the end of the twist over the section of hair you want removed and move the thread in a swift motion. The twisting motion traps hairs between the threads and lifts them out whole.
