Threading is an ancient method of hair removal originating in Central Asia and India. In threading, a thin (cotton or polyester) thread is doubled, and then twisted. It is then rolled over areas of unwanted hair, plucking the hair at the follicle level. Unlike tweezing, where single hairs are pulled out one at a time, threading can remove short lines of hair.
Advantages for eyebrow threading, as opposed to eyebrow waxing, are that it provides more precise control in shaping eyebrows and is gentler on the skin. It can be painful as several hairs are removed at once.
There are a few different techniques for threading. These include the hand method, mouth method and neck.
Threading allows for a more defined and precise shape and can create better definition for eyebrows. It is also used as a method of removing unwanted hair on the entire face and upper lip area.
