Before entering the ring, boxers must have a clean appearance, facial hair must be trimmed, and their hair must be trimmed or tied back with soft and non-abrasive materials in such a way as not to interfere with the vision of either boxer or cover any part of the boxer's face. Boxers shall wear no facial cosmetics. The Commission, in its discretion, may require a boxer to wash, trim hair, tie-back hair or shave prior to a contest or exhibition to the extent deemed necessary to ensure health, safety and the integrity of the athletic competition.
