Why Threading Works for Brows
Threading is a centuries-old technique. A twisted cotton thread lifts hair out at the follicle, row by row, for a clean, defined shape with no chemicals on the skin. Waxing lifts a layer of skin along with the hair. Threading removes only the hair.
The thread gives precise control around the brows, removing individual hairs and cleaning up small areas without disturbing the surrounding hair. That makes it especially useful for defining the brow line while keeping the shape intact.
