try shaggy, wavy effect :





This one is easy to do. Shampoo and condition your hair. Towel dry. Apply a mousse or other styling product lightly to your damp hair to give it some texture.. While your hair is still damp, bend your head over so you're drying your hair upside down. Dry your hair with the blow dryer while using your hands to scrunch it. Once your hair is dry, throw your head back and immediately spray with silvikrin Flexible Hairspray .What are some good hair styles that are easy to do in 30 minutes?
I like to braid my bangs down (do french braid down the side of your head) then you can either pull the rest into a pony tail or leave it down.





get some curling gel and put it in your wet hair before bed, wake up to a tangle of curls and either put an elastic headband in it, or pull it back without brushing it.





wear your hear in a low pony tail slightly off center (not a bad 1980's do) so you can play with it during boring classes








i hope this helps
have some hair spray just use ur creativity
