Members of Canada's military will soon be soldiering under much less strict dress rules as the Canadian Armed Forces (CAF) introduces updated regulations on personal grooming.

Axar.az reports citing foreign media that under the new rules - which were released Tuesday and go into effect in September - CAF will allow military personnel to, among other things, colour their hair and grow it to any length, and to sport face tattoos.

"The bottom line is, the Canadian Forces Dress Instructions are about fifty years old and so the policy as a whole was overdue for revision," says a Department of National Defence (DND) Frequently Asked Questions (FAQ) page detailing the update.

"The appearance of the Canadian Armed Forces (CAF) has not kept pace with the Canadian society which it serves."
