Threading removes the entire hair follicle, lasting up to 6 weeks. A cotton thread is pulled along unwanted hair in a twisting motion, to trap hair in a mini lasso, and lifts hair right out of the follicle. It’s extremely sanitary. Nothing but the thread touches the skin, and it’s thrown away after use. Temporary results can turn permanent over time. Frequent threading can cause the hair follicle to stop growing hair.
