Threading is an ancient method of hair removal which originated in the Middle East.
Threading the entire face is widely spread amongst Iranians, but it was originally practiced when a woman was getting married or during special occasions. It is now gaining popularity in Western countries as an alternative to eyebrow waxing and plucking.
A thin, twisted cotton thread is rolled over untidy hairlines, plucking the hair at the follicle level. Unlike tweezing where a single hair is pulled out each time, threading can remove an entire row of hair, resulting in a straighter line.
The advantages of using this technique, instead of waxing, are that it provides more precise control in shaping eyebrows and is more gentle on the skin.
