I rinse my hair with white vinegar. Occasionally I use Dr.Bronners if my hair smells bad. I literally cannot use shampoo, my hair is too thick and it doesn't rinse out...my hair just gets really grimmy and gross if I use shampoo.
I once did a castor oil hair treatment and could not for the life of me get the oil out of my hair. I used every natural alternative I could and I ended up having to use regular shampoo to get it out. My hair felt weird from it, but only for a day or two. So I doubt you've set yourself back too much (:
