Threading is an extremely safe depilatory method as the skin is not traumatised or exposed to heat. It is a great alternative for people with sensitive skin or those who suffer from acne. Unlike tweezing, threading removes one clean line of hair all at once, making it much quicker and easier to shape the brows. Threading can be used to eliminate a unibrow, raise the arch of the eyebrow, or add shape and definition to the brow. Threading is much kinder to the skin and is considerably less painful than other methods of hair removal.
