Once upon a time, beards were considered a seasonal affair. Big, woolly face mitts in winter gave way to crisply shaven chops when the sun came out in May or June.

"A good beard doesn't have an expiration date," says Michael O'Malley, a barber in Boston. "You just have to treat it right in the summer to keep the heat from messing things up."
