What to do about thinning hair at such a young age?

I'm 21 and have had thin hair all of my life. However, over the past two years it seems to be noticeably thinner. If i wash my hair in the morning, by late afternoon it looks straggly and greasy. i have tried volumizing shampoos, creams, etc. Nothing seems to work. I recently looked into something called "interlock" which looks great (non surgical), but it is $4,000 every two years. Anyone have any suggestions about what to do? Anything you've tried?
