I tried something on my Appy who naturally has an amazing tail but toward the top of his tail bone or dock right before his butt the tail hair was breaking off. I had gotten some samples of this (I can't remember what its called. But I know the fly spray made by the same company is made of marigolds. ) and one was conditioner, color enhancing shampoo, and another was some sort of aloe gel. Well I took a spray bottle put 2 parts of the aloe gel in it and 1.5 parts conditioner and filled the bottle 1/3 way with water and shook it up really well. I sprayed it on and it worked pretty **** well if you' ask me. A noticeable difference.
