This popular volume on the culture of hair through human history and around the globe has been updated and revised to include even more entries and current information.How we style our hair has the ability to shape the way others perceive us. For example, in 2017, the singer Macklemore denounced his hipster undercut hairstyle, a style that is associated with Hitler Youth and alt-right men, and in 2015, actress Rose McGowan shaved her head in order to take a stance against the traditional Hollywood sex symbol stereotype.This volume examines how hair-or lack thereof-can be an important symbol of gender, class, and culture around the world and through history. Hairstyles have come to represent cultural heritage and memory, and even political leanings, social beliefs, and identity. This second edition builds upon the original volume, updating all entries that have evolved over the last decade, such as by discussing hipster culture in the entries on beards and mustaches and recent medical breakthroughs in hair loss. New entries have been added that look at specific world regions, hair coverings, political symbolism behind certain styles, and other topics.
