“In 1971, Germany’s Armed Forces lifted a rule that conscripts could only have close-shorn hair. The only restriction was men with shoulder-length manes had to wear hair nets - the Armed Forces ordered 740,000 nets. Some soldiers worried wearing nets for extended periods could be damaging to their health. The Forces appointed a commission to investigate.
“Doctors stated it was impossible to care for long manes in a way that would make them fit for combat. The commission also noted longer hair required greater amounts of water, as well as hair dryers, putting a strain on military budgets.
“Fifteen months later, the defense minister decided a soldier’s hair could not touch his uniform or collar and that hair could not cover a person’s eyes or ears.”
