Is my dream hair UNREALISTIC?!??

Hello.Funny you should post this question because this is exactly the hairstyle that I have. My hair length has been from waist length to a boy`s cut. Whenever it got to waist length I got bored and tired of it because it was just one length. It was very heavy and, like you, I kept it in a pony tail most of the time. (This is probably why I ended up cutting it). In any event, I am letting it grow again, and it is currently just below my bra strap in the back. Right now I part it to the side, and it has about 4 different layers, the smallest being chin-length. I love it because since I have such thick , thick hair, it takes off some of the weight and my hair is just so full of bounce and volume. But, I must say, I went to a VERY expensive hairdresser, and only after I saw how she cut my cousin`s hair. I would recommend this style to anyone, but you MUST go to someone who DEFINITELY knows what he/she is doing!!!!!!

i was thinking of getting my hair layered but now im a little hesitant b/c i`ve been warned against it but i really want to do it....im not sure!

My hair is waist length, im thinking of having it trimmed two inch and then layered. Layers starting from my shoulder and getting longer in steps. I keep my hair tied in a ponytail a lot so what do you all think and why?

I dont want to keep it all one length cuz i dont like it like that but i dont want it short either, its the perfect length and its really straight which i like, i just want some style so then maybe i can keep it out more if its shorter from the front and stuff.

ALSO, waht are the types of layers there are???? Know of any websites on layers that would help please.???

Please help with your suggestions,

much appreciated, thanks
