natural hair dyes

I really want to dye my hair but i'm allergic to most brands and come out with hideous blisters on my head whenever I use them.
I read that you can use lemon but I don't want to dry our my hair plus I work nights, so I don't see enough sun for it to work. I also read that honey will work but I don't want to try before I know if its any good.
Has anyone tried it?
Also if you have pictures that would be great. My hair is a light brunette colour now and I want to be blonde again.
I tried cinnamon but it made no difference at all except for the smell, which took a long time to get rid of.
