I love cowboy magic or the cheap generic silkener. Wash and condition the tail first then work in a very generous amount of silkener. Work it in for a few minutes. Wait for it to dry in there. I left it over night because I had a show the next morning. When I came in the next morning her tail was SO soft. I added another palm full of detangler, worked it through again and within a minute my brush was going from top to bottom no problem. This a mare who usually grows dreadlocks for a tail! It was like to good to be true!
