What to do with my hair?

i have recently got it cut from the hairdresser and i liked it to start with but after a few weeks, im starting to get annoyed with my layers :/ they go about 3 quaters down my hair and i reckon they are too long. I want shorter layers that make my hair look more volumised because the top of my hair is really limp but thee rest is wavy. I cant go back to the hairdresser. Is there something I can do to get the top of my hair more volumised? I dont want to straighten it and tease it everyday D': I hear it recks hair. plz help me!! 10 points!!!
