Untamed facial hair – along with fixed-gear bikes, vintage clothes and coffee alchemy – has become one of the unmistakable calling cards of hipsterdom.

Predictably, then, bare faces are something of a rarity in Brooklyn – by far the trendiest of New York City’s five boroughs – though the high density of hasidic shuls in the area has as much to do with it as the artisan bakeries.
