My hair is way too frickin greasy?

I'm at school now and I'm not a morning person. I don't like to shower in the morning because I like to sleep in. Plus it's just easier since I have to get myself off to school a lot. So I like to get all my stuff done at night and take a shower then, but by the time I wake up, my hair is all greasy. I'm using axe shampoo, currently shampoo+conditioner but I've had this problem with shampoo, even the deep clean stuff. So how do I keep my hair from getting so frickin greasy by morning?
