Staff Sgt. Antoine, 13th Intelligence Squadron intelligence analyst, raises his head as Lt. Col. David Gregory, 9th Medical Group flight surgeon chief of medical staff, inspects his neck and face during a shaving waiver course at Beale Air Force Base, Calif., March 15, 2018. The most common reason Airmen request shaving waivers is due to pseudofolliculitis barbae, which is also known as shaving bumps or ingrown hairs. (U.S. Air Force photo by Senior Airman Colville McFee)
