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.

Advantages cited for eyebrow threading, as opposed to eyebrow waxing, include that it provides more precise control in shaping eyebrows, and that it is gentler on the skin. A disadvantage is that it can be painful, as several hairs are removed at once; however, this can be minimized if it is done correctly, i.e. with the right pressure.[2]

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. Threading is not a good method for removing hair on arms or legs, as the hair in those regions is typically quite coarse and there is too much to remove.
