What is threading not good for?
Threading is not good for large areas of hair as the thread can get clogged up. Also, this method can be challenging on tough, coarse hair. Areas such as on a man’s back, jawline, and legs would be better treated by another method such as sugaring. Threading also has problems removing hairs on irregular surfaces; for example, on the bikini line and knees. This method is best performed on flat surfaces.
