Figure 1: (a) Threading is commonly employed at beauty salons for eyebrow hair removal and shaping. Initially, one end of thread is anchored, usually in the teeth of the operator, while the other end, which is coiled multiple times, glides over and entraps unwanted hairs. This maneuver is used to remove multiple hairs simultaneously with one swift pull. b) Subsequently, the skin surrounding the eyebrow is held steady for more precise shaping and removal of single hairs. Maintaining tautness not only eases the extraction process, but is also thought to reduce pain associated with the procedure.
