I recently had my very straight and pretty fine hair cut into a graduated bob. It looks fine when I have blow dried it, especially if I have used something to give it volume (I've got an Aveda liquid gel type thing), but the day after it always looks a bit shit, and a bit greasy if I have put some stuff in it. Or sometimes I wash it but don't get to dry it and style it straight away. I use straighteners to curl it under but it still looks a bit crap.
What can I oomph it up with without having to wash it again?
