want to get a perm need advice

okay im an asian male with typical asian hair. before it wouldnt go down i kind of got it to go down with growin gout my hair but it has no texture at all and looks like one layer and hard to style do to stiffness. my strands look so thin and my hair looks ugly when pushed backwards or even strait down. it has no texture so it looks like jet black thin hair resting on my head. and when i try to get it backwards it barely stays due to stifness and doesnt have any volume. its so flat on my head and looks real ugly. so i was wondering how do i get a perm on my hair, i dont want curly hair i just want waves to make my hair have more texture. i want to push it backwards and have that wavy look, with different layers or i want to keep it down with texture and different layers not what i have now the one layer, so thin, no volume, asian thing. also will this help my hair to be softer so i can bend it and style it?

this might sound stupid... but what do you mean of wave?? i dont know taht? could anyone point me to a picture of it?thanks
