In threading, a thin (cotton or polyester) thread is doubled, 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 rows of hair.

Threading provides more precise control in shaping eyebrows and is gentler on the skin. It can be painful as several hairs are removed at once; however this can be minimized if it is done correctly with the right pressure.

​There are a few different techniques for threading. These include the hand method, mouth method and neck method. Each technique has advantages and disadvantages; however, the mouth holding method is the fastest and most precise.

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.
