Question: can you grow a beard in the us navy

title: Facial hair in the military
text: In the Royal Netherlands Army , officers and soldiers may only grow beards after permission has been obtained . As in many other armies , automatic permission is given for certain medical conditions . Mustaches may be grown without asking permission . Beards are worn at times by the Royal Netherlands Marines and by Royal Netherlands Navy personnel . All facial hair in the Netherlands armed forces is subject to instant removal when operational circumstances demand it . Recent operations in Afghanistan under the ISAF have seen a trend of growing `` tour beards '' , both for bonding and as a way of advancing contacts with the Afghan population , who regard a full beard as a sign of manhood . A beard without a mustache is uncommon in the Netherlands .
