This chapter examines changing views on haircare, health, and gender in Sweden from 1740 to 1840. By investigating haircare in recipes, journals, and advertising, the chapter outlines the connections drawn between outer appearances and inner wellness in the early modern period. It also shows how these connections were gendered. In the eighteenth century, hair was commercialised through the use of wigs and a growing market for haircare recipes. These recipes were a mixture of health cures and cosmetic concoctions. By the early nineteenth century, haircare manuals were becoming more gendered than before. Books about haircare for men were focused on hair as a signifier of health, while haircare and advertising for women was concerned with hair as a signifier of beauty.
