I have given up trying to find a toothpaste here in the UK at least, John. I use 1 drop of peppermint essential oil in the morning and 1 drop of teatree essential oil at night and brush really well. Seems to work. I had a terrible gum infection which led me to the realisation of gluten sensitivity and as soon as I removed gluten from my diet and, importantly, stopped putting anything suspect in my mouth dentally-speaking, my so-called 'infection' which 5 lots of very strong antibiotics had failed to stop, went. Nuff said.
Shampoo – I use an Oxfam range here but to be honest I wash it off really quick so if anything is in it, it doesn't have time to absorb!
