Section 14.03 - Physical Appearance of Unarmed Combatants

(1) A light layer of grease and nothing else may be used on a combatant's face, not to extend behind the ears. Grease may not be used anywhere else on the combatant's body. The referees or the Commission's representative in charge shall cause any excessive grease or foreign substance to be removed. Combatants shall be examined by a referee or Deputy Commissioner prior to entering the ring or cage to ensure that improper or excessive amounts of grease are not present.

(2) The Commission's representative shall determine whether head or facial hair presents any hazard to the safety of the unarmed combatant or his or her opponent or will interfere with the supervision and conduct of the contest or exhibition. If the head or facial hair of an unarmed combatant presents such a hazard or will interfere with the supervision and conduct of the contest or exhibition, the unarmed combatant may not compete unless the circumstances creating the hazard or potential interference are corrected to the satisfaction of the Commission's representative.

(3) An unarmed combatant may not wear any jewelry or other piercing accessories while competing.

(4) Finger nails shall be of a length so as not to be able to inflict injury to an opponent.
