I use the Cowboy Magic Detangler. Its pricey for the bottle but its really amazing stuff and will last you a LONG time. You only need to use about a dime size every time you use it and its not something you have to use all the time. It conditions, detangles and it keeps the hair really manageable. I don't know if you can get that in the states (im in Canada) but you can get it at the tack stores here. I wash his tail when needed but for the most part I just take it out of the bag, put some stuff in it and put it back up. You can use pretty much anything though for conditioner, I use the mane and tail shampoo/conditioner, its never done me wrong and its quite inexpensive.
