Know of anyone with a goat?
Equal parts of goats milk and water mixed in and sprayed on will condition, detangle mane & tail and put a luster and sheen unmatched on the coat...
REFRIGERATE THE UNUSED PORTION...it is milk and will curdle and spoil.
Watched a Paso Fino trainer/groom do this and asked...he had the most awesome horses to look at and so soft to touch!!
And NO, it doesn't make the horse smell bad either!!
