Hair needs help!?

Iim just getting ready for my grad photos right now and I'm the type who takes these things very seriously.I just did my hair super nice....but I walk to school and I'm afarid that if I try to cover my head with my hood it'll be recked.Even if I don't leave my hood on,my hair will fall to pieces anyway...Is there any methods you guys recommened?(Tried hairspray...lol)
