Threading is an ancient Middle Eastern technique that is becoming common in the United States with threading shops popping up in every big city as we speak.
An aesthetician uses a doubled-up strand of cotton thread to twist around individual hairs, then pulls them out from the roots. The procedure is used mainly on the eyebrows and upper lip.
Threading is faster than tweezing. The average eyebrow procedure takes about 5 to 10 minutes, while tweezing takes about 20 minutes.
