I agree that generally hoof dressings don’t do much, and if you don’t fix the cause of the problem you’re just going to be fighting a never-ending battle.
A good diet is essential to good feet – if your horse has especially bad feet he might benefit from a hoof supplement as well.
A good farrier/trimmer is even more important.
Though, some horses do just have bad feet.
As far as topical treatments go, I use Keratex hoof hardener. It’s not really a hoof dressing or oil, instead it is a chemical that alters the structure of the hoof, strengthening it.
