I need help with a hair style...?

Im a guy with dark dark brown pretty much black hair. My hair is really straight and fluffy especially when i get out of the shower or if I am sweating and it gets wet or damp. I like the way my hair looks whenever I wake up it the morning and its not all fluffy but as soon as i sweat a little and it gets kinda damp it gets fluffy. Sometimes I can keep my hair the way it is when i wake up sometimes i cant. I gyess it depends on if it gets damp or not. So my question is, is there anyway I can keep my hair the way it is when i wake up. Like any hair gels or hairspray, or any tips at all would help. Thank you!
