Some supermarket breads are made with human hair dissolved in acid, part of a dough conditioner that accelerates industrial processing. The mender does not eat bread from the supermarket, and she has her own supply of hair, which instead of dissolving in acid she grinds into her mixtures. She keeps head hair in a separate box from pubic, as they’re good for different things—pubic has more iron, head more magnesium and selenium. The mender’s supply came from one person and is dwindling.
