The benefit of threading that most sets it apart from other hair removal techniques is its precision. While waxing and plucking can often leave unwanted stray hairs around your eyebrows, a threading artist goes through your hair row by row, giving eyebrows a clean and defined shape. Threading only removes hair, not skin, and because it is so exact, it can remove hairs that are finer than those that can be removed by waxing or plucking.
Threading is also very fast -- sessions will only take about 15 minutes of your time, and sometimes even less. It's also relatively inexpensive. Different practitioners have varying rates, but threading generally costs about the same as plucking and waxing [source: WebMD].
People on particular medications or with certain skin conditions may turn to threading to remove their hair because it's gentler on the skin than some other types of hair removal. For example, some dermatologists recommend that people who use acne medications -- including Accutane and topical retinoid creams -- choose threading over waxing because the former only affects hair and not the skin underneath. Waxing, on the other hand, can remove a layer of skin along with the hair, especially in people whose skin has become more delicate or fragile in response to treatments [source: Kazakina]. Also, allergic reactions to threading are rare, because the only equipment used is a simple cotton string instead of a wax, for example, that could contain irritating substances.
Though the point is debatable, some say that threading is less painful than waxing and plucking [source: WebMD]. This, again, could be due to the fact that threading has much less contact with the skin than the other procedures. Additionally, many believe that your hair will grow back thinner after multiple threading sessions [source: Blacksberg].
As good as it may sound, even threading has its downsides. Read on to find out what they are.
