Threading works by doubling a cotton thread and twisting it to make the figure 8. It is then rolled over the hair that is to be removed, plucking the hair at follicle level. Threading gives a more defined and precise shape to brows and can be used as an effective way to treat hair on the entire face including the lip and chin. Unlike tweezing or waxing, threading does not create ingrown hairs and is safer for all skin types.
