Janet Stephens is a hairdresser who has been working to recreate Roman hairstyles using the techniques of the time. You may have seen her links to her Vestal Virgin hairstyle going around this past week, but she has a great many more Classical hairstyles recreated on her YouTube channel: http://www.youtube.com/user/jntvstp. There is a Greek one that ties up the hair with a simple band of cloth and the famous Flavian one.
