Threading is a hair removal technique that has been practiced for centuries. Facial hair is removed swiftly yet meticulously from the most delicate areas of the face by knotting off thread and creating a trap that forces out hair by the root. It is the best alternative to waxing and tweezing, especially for sensitive skin. Unlike waxing, threading does not remove a layer of skin, which can leave the skin on your face susceptible to sun damage. By far the least invasive method of facial hair removal, threading can target individual hairs to get the precise shape and smooth finish you want.
