Hair oil used by 'amahs'

This bottle of Girl Brand Hair Old (双妹墨生发油, shuangmei mosheng fayou) was one of the few personal 'luxuries' that 'amahs' (domestic servants) possessed. These women from the Pearl River Delta in China were known for their frugal ways, choosing to remit most of their earnings back to their families in China rather than splurging on consumer items.
