The threading is an ancient process that originated in India. It involves doubling up of thread, then twisting and rolling over areas of untidy hair line which removes those hairs at the follicle level. When compared to tweezing, where single hairs are pulled out one at a time, threading can remove short lines of hair. Threading process allows the hair to be removed in a uniform line ensuring a nice arc to the Eyebrow.
Eyebrow threading is considered better than eyebrow waxing as it provides more precise control over eyebrow shaping and it is gentler on the skin.
There are a few different techniques practiced in threading which includes the hand method, mouth method and neck method. Out of these the mouth holding method is considered accurate and quick.
