I second the clipping for volume but a couple of other ideas are:

- Do your hair drying up side down
- Dry shampoo, Its the bomb! I often go flat at the back of my head, i spray a little on to the base of my roots and I get quite a bit of lift.
- There are volume powders that you shake though your hair, they do a really good job for some of my friends with very fine limp hair.
