Beauty type question wrenn or shelley

Hi girls! I have a question about my hair.

I have straight hair, not a bit of body to be found. I have let it grow out to find it only just hangs there and am contemplating going back to the shorter bob tomorrow. My main problem is that I have no time to throw some hot rollers in it in the morning because my hair must be washed fresh each morning due to it getting oily. I have tried washing it right before bed and it usually stays somewhat clean til about noon the next day. When I use hot rollers the curl usually falls out within half an hour or so (florida humidty) but stays bouncy and body like and looks alot nicer. Is there any kind of wash I can do at night?? I think I must sweat alot at night or something. My genetics make me oily, this I know for sure (cherokee indian and some other stuff) But I am so tired of my shorter hair style it is vary hard to do something new with my hair, I would never have another perm in this lifetime, and when you cut layers in my hair if I leave it straight it looks like I got a really bad haircut. I know this is small stupid stuff, but thought I would ask anyways.
