Threading is a hair removal technique that uses a twisted cotton thread to pull out unwanted hairs from the root. This method of hair removal originated thousands of years ago in the Middle East and India - making its way across the world. Eyebrow threading is a popular alternative to tweezing, waxing, and shaving. Tweezing is a hair removal method that takes forever and every pluck is painful. Many waxing horror stories have reported top layers of skin being ripped off. Many feel absolutely nothing during the threading process, while others may experience some discomfort and reddening of the skin.
