Bob hairstyles are a short to medium length style in which the hair is generally cut straight around the head at about the jaw line, often with bangs and/or a fringe of sorts.
The bob hairstyle was first made popular in the early 1920's when American film star Colleen Moore dawned the style.
Bob hairstyles are still a very popular choice of design, and worn by many famous celebrities including Rihanna, Charlize Theron, and Keira Knightley to name a few.
