Threading has been used to remove unwanted facial hair since ancient times. It is a common method used in the East. When properly done, it can be used to shape the eyebrows with a clean defining edge. The procedure utilizes a length of thread which is twisted back and forth along the hairs to be removed. The twisting action of the procedure traps the hair and lifts it out of the follicle. This method of hair removal is more effective and less painful than tweezing.
