Threading is one of the most used methods to remove unwanted hair from the face. It helps you get rid of hair on the upper lips and other parts of the face. Threading is also used to give the perfect shape and length to the eyebrows so that they look maintained and also graceful at the same time. Threading needs to be done regularly otherwise the hair will start to re grow. Threading is slightly painful but has no unwanted side effects that are associated with other hair removal methods.
