Help with my hair, please.?

Okay so here it goes. My hair is originally a light brown color. I had this thing for a while where I dyed my tips different colors. The dye that I use is semi permanent. Well my friend had the idea to bleach my hair. Bad idea.This turned out like a nightmare. Anyways, the next day, we promptly dyed it a color. The dye job was good. The color was dark blonde. Anyways, that is growing out and my roots are showing badly. I want my old color back. Is this possible at all? I don't want to try at home kits. And I'm broke and have no money for professionals. Natural ways are welcome.
