Every time I find something that doesn't seem to contain coconut, it contains wheat.
Have you tried making your own, and if so, how did that work? Maybe you can contact someone who makes things locally and see if they can make a conditioner and shampoo to your specifications.
When I was in Pennsylvania last year, I bought lotion and soap from this business: http://www.sassyalbertsoap.com My father in law said they would make things upon request. They have a shampoo that contains wheat protein, but I wonder if they could make it without that. The ingredients are: organic aloe juice, organic lavender hydrosol, Roman Chamomile, vegetable glycerin, wheat protein, Vitamin B-5 and Vitamin E, rose-hip seed oil, jojoba and essential oils of Australian tea tree, peppermint...........16 oz
This site has gluten free shampoo, and they say that you can ask about coconut free soap: http://gfsoap.com/shampoos.html
