hair cut help

I have naturally curley hair, but i blow dry it every morning so it gets straight, My hair is about 2 inchs below my sholders, browen/with red hints, and the cut is all even at the bottem. I want to Layer my hair a little at the bottem so it dosen`t seem so dull, like some people have in maagazines and celebritys, but im afriad that I might ruin my hair and regreite it, should i go for it or forget it?

Thanxs john,
but the thing is i do like my hair, but im bored with it i mean i think it`s pretty but i don`t even think most people would notice it at all. It probley woudln`t even be half a inch. I dont know tho somthing still tells me i should, and somthing tells me i shouldn`t.
