Shaving is the removal of hair, by using a razor or any other kind of bladed implement, to slice it down—to the level of the skin or otherwise. Shaving is most commonly practiced by men to remove their facial hair and by women to remove their leg and underarm hair. A man is called clean-shaven if he has had his beard entirely removed.
Both men and women sometimes shave their chest hair, abdominal hair, leg hair, underarm hair, pubic hair, or any other body hair. Head shaving is much more common among men. It is often associated with religious practice, the armed forces and some competitive sports such as swimming, running, and extreme sports. Historically, head shaving has also been used to humiliate, punish and show submission to an authority, and in more recent history also as part of fund-raising efforts, particularly for cancer research organizations and charitable organizations which serve cancer patients. The shaving of head hair is also sometimes done by cancer patients when their treatment may result in hair loss.
