The mats stored in southern Miami-Dade County are part of a world marketplace for human hair. Uses range from the obvious, such as false eyelashes and wigs, to the more obscure: it’s a common raw-material source for l-cysteine, an amino acid frequently used in baked goods such as pizza dough and bagels.

China and India exported more than $154 million worth of human hair last year, according to United Nations trade statistics. They are Blacker’s main suppliers.
