Rule 4-2 sec 2 (in part) Physical hair treatment items that are hard and/or abrasive such as (beads, bobby pins, barrettes, pins, hair clips, etc. or any other hair control device) shall not be permitted. A legal device hair-controlled such as rubber band(s) shall be secured so as not to come out readily during wrestling. A wrestler may contain his/her hair in a legal hair cover. The legal hair cover, if worn, shall be attached to the ear guards. A bandanna is not considered legal hair covering. The legal hair covering must be of a solid material and be nonabrasive. The wrestler opting to wear a legal hair cover must wear it to the weigh-in procedure and be checked for grooming with it on. The legal hair cover must be removed prior to the wrestler stepping on the scale to be weighed. If the referee is not present at weigh-ins, the hair cover must be checked by the meet referee upon arrival at the site.
