I have not actually used it, but Buddy Wash is what I plan on getting. There was a thread a while back and it was like 10 pages of which brand people used, and Buddy Wash and Cranberry Fields were the highest. I think it is the cheapest at amazon you can get shampoo, conditioner, and spray detangler for $19.
