Beard suppressant

Shaving is the practice of removing body hair from a humanoid body, usually with a razor or another implement designed to slice the hair away from the body. It is most commonly performed by men to remove facial hair to keep a beard from growing. Shaving is also used to shave hair from other parts of the body - such as the head - by both males and females.
