well i use M.T.G you can get it at any local supply store. i love the stuff! my horse had rain rot, and i used it on that it cleared up, then i started putting it on his mane and tail---wow huge diffrence!! his top hairs started growing out on his tail and it thickened up! so did his mane! i also know the saddle bred people at my barn use it when their horses rub their tails. it is a little pricey, but it will last you forever! good luck!
