With the excepption of shaving and threading, waxing is a preferred technique of hair elimination. One more sticky substance is often appled on the part of the skin that is going to be waxed. The second part of the process includes removing of the substance and with that the hairs. For this reason it is also more effective than shaving, as the hair is pulled out from the roots instead of cutting it on the level of the skin. According to practitioners of esthetic waxing, depilation may be done on almost any part of the human body including the legs, arms, eyebrows and the bikini region. This can be quite uncomfortable at times, however the hair-free smoothness can last up to several weeks.
