My horse has a skin condition where when he sheds, it comes off in strips. Not hair by hair like normal. We have looked into it and we are positive it isn't rain rot. The hair underneath is thin and there isn't very much of it. The weather can change drastically here from rain to sun in a matter of minutes. He needs some hair on him. Its been growing back fairly well. But is there a product that can help hair grow? Someone told me coconut oil does the trick. Does anyone know if that's true or not?
