The voices that commanded the teenage Joan to don men’s clothing and expel the English from France also told her to crop her long hair. She wore it in the pageboy style common among knights of her era until guards shaved her head shortly before her execution. In 1909, the Polish-born hairdresser known as Monsieur Antoine—one of Paris’ most sought-after stylists—began cutting his fashionable clients’ tresses in a short “bob,” citing Joan of Arc as his inspiration. The look really caught on in the 1920s, popularized by silent film stars and embraced by the flapper set. While women continue to request bob cuts to this day, another of Antoine’s legendary experiments—dyeing his dog’s hair blue—hasn’t stood the test of time.
