Men set aside from other men because they grow either their hair, their beards, or both longer than the cultural norm. Longhairs may be a target for ridicule in some situations, including the possibility of employment or being called 'hippies' but have a genuine resolve to grow long hair in spite of all criticism. Longhairs come from all types of political and socio-economic backgrounds and are not characterized by one example in particular.

"I think I've got a better chance at getting this job because I'm clean-shaven and the other guys that interviewed were a bunch of longhairs.
