Under new Air Force standards, fewer airmen will be able to secure shaving waivers that allow them to grow beards.

The Air Force is resetting the expiration dates on waivers for airmen and guardians with shaving exemptions, or profiles, according to a memo from service’s surgeon general.

Airmen and guardians will have to undergo a medical evaluation to receive another shaving profile, an Air Force memo says.

Medical shaving waivers for thousands of airmen and Space Force Guardians will be reset and reevaluated, according to new Department of the Air Force memos.
