How to give yourself layers/ Brighten hair color?

I love to cut my hair, but lately I kinda feel like it's falling flat :P I have a little longer than shoulder length blond wavy hair and side bangs- any suggestions? And is there any methods I could use to possibly brighten or enhance hair color without damaging- drying out my hair (believe me, i've heard the lemon juice method a million times :P ) any suggestions would be great :D
