How do I keep my hair from moving out of place?

use a fair bit of hairspray, but the more you put on, the more it gets weighted down. personally, i've never been able to keep my hair big all day, so you'll have to keep touching it up throughout the day. also, using a textureiser gives hair something to stop it being slippy if you know what i mean. i'm not sure of the brand but i think wella do one, in a bright green pot, and the stuff is grey inside.
