The bob is the classic short hairstyle for women, cut to chin length. The bob has been popular as a hairstyle for ladies since the 1920s. In a hundred years, many new variations have emerged from the once daring short women's haircut: long bob (lob), clavi-lob, wob, shaggy bob (shab), pixie and page and ever more trending variations make this cut one of the most popular hairstyles of all time.
