Threading is an method of hair removal originating in the Eastern world. We use thin thread and twist around into a figure of 8 and roll it over the area of unwanted hair, then it plucks the hair at the follicle.
This removes the short fine blond hairs, comparing threading to waxing it can be more harsh on the delicate skin of the face. The hard pulling of the wax over time can cause the skin to sag and droop. Wax can break the hair at the bass of the follicle in stead of pulling it out from the root.
Threading is perfect for people who like precision in their brows. This method of hair removal is fantastic all over the face(eg. lip, chin, sides of face) removing the fine hair that makeup gets lost in.
