I have not tried the Cowboy Magic but just finished up using the Mane and Tail shampoo and conditioner and I thought it worked as well as any other I've used. I used it sometimes on my hair as well
It's easy to find and last time I checked Petsmart had a huge bottle of the shampoo and cond. for a good price. can't remember the price but the bottle were huge! It was a special offer
