When I first got my gelding he had a thin coat with a sparse mane and tail. I started him on Omega Horseshine and his coat grew in much thicker and his mane and tail are fuller now. Even the vet commented on how wonderful he looked. He hasn’t had any skin problems or itchiness since using this product either. I put all my horses on it and now when you look out in the pasture, you are almost blinded by the sun reflecting off of their coats!
