Bikini waxing is the removal of pubic hair using a special wax, which can be hot or cold, that adheres to hairs and pulls them out when the wax is removed quickly from the skin, usually with a cloth strip. While the practice is mainly associated with women, male waxing is sometimes done to remove men's pubic hair.
A bikini line is the area of the upper leg and inner thigh in which pubic hair grows that is normally not covered by the bottom part of a swimsuit. In some cultures, visible pubic hair in this region is disliked and/or considered embarrassing and so it is sometimes removed. However, some people remove pubic hair that will not be exposed for reasons like aesthetics, personal grooming and hygiene, culture, religion or fashion.
