For my hair, I am thinking about trying the method suggested in this blog post:
Why I Ditched Shampoo (And How You Can Too!)
I've tried deodorants without aluminum, but I haven't been very successful. Tom's Of Maine just gave me a red, burning rash and didn't work well! Booo! Since then, I've been afraid to try anything else different. Also, I'm in martial arts and thus, I need a good deodorant. I'm open for suggestions to this as well. Oh, and I need to be able to get it in the UK. :o)
Anyway, I'm still doing some research, and I'd appreciate any feedback or experiences.
