Is an ancient method of hair removal which originated in the Indian subcontinent, spread to the Middle and Far East, and is now gaining popularity in Western countries. Practitioners use a pure, thin, twisted cotton thread which is rolled over untidy hairlines, and so on, plucking the hair at the follicle level. Unlike tweezing where a single hair is pulled out each time, threading can remove an entire row of hair, resulting in a straighter line. As the top layers of skin are not peeled or traumatized, threading is an alternative for those with sensitive skin or who use Retin-A, Accutane, and similar products.
