Grooming standards play a vital role in the promotion of good order and discipline. While beards are not normally authorized, commanders may allow facial hair, per reference (a), when a medical officer has determined that shaving is temporarily harmful to the Marine's health. PFB, also known as shaving or razor bumps, is a chronic skin condition caused by shaving. By following the protocol contained in enclosure (1) , PFB can often be managed to minimize its effects and allow shaving in compliance with grooming s t andards . Commanders should be aware that the condition can recur even after successful initial treatment when mission fact o rs prevent s t r i ct adherence to PFB maintenance care. I n this situation, t he Marine may require additional treatment to include laser treatment. Enclosure (1) describes the treatment protoco ls and the time p e riods medical will recommend to the command that the Marine be e x cused from shaving . For those cases where a permanent "no shave" status is recommended by a medical officer, reference (b) describes administrative actions that may be considered . Permanent variance f rom the established grooming standards for any reason, including medical, will not normally be accepted.
