Joanna Bourke, Professor of Rhetoric at Gresham College in “A History of Hair” argues that:

“Part of the reason that hair is so central to personhood is because it sends out signals to oneself and others about gender, class, status, age, generation, marital status, religion, group membership, familial ties, and politics. It is personal, but it is also a highly visible cultural artefact.”
