Olive Oil on Everything?

Here is something random, but it actually makes a lot of sense. Some celebrities swear by putting extra-virgin olive oil on your face, hands, and hair. Honestly, I was pretty nervous about this. Isn't oil exactly what you're not supposed to put on your face? I don't know about the hair idea…but I've tried using it (cautiously with a q-tip) on the dry spots on my face in the winter and have been really impressed with the results. Someone else is going to have to chime in on this one!
