You can imagine my reaction when I saw that you were suggestion stuff for a horse, but then I remembered a time back in the 70s or 80s when horse shampoo was very popular. I'll keep it in mind as I shop and see if I can find it in a local store or stable . Seriously, maybe I'm just cheap but I hate to spend $3 for something that costs me an additional $4 to ship. I doubt you would believe the number of topical products I've tried, from salves to ointments to polishes. And my dermatologist suggested Biotin, so I've been taking 2,000 mg of that for more than 2 years, but to no avail. And that's way longer than the 1 year I was told would have to pass before I could see any change from the Biotin (it takes a few weeks for the Biotin to build up in the body and then the nail takes something like 6 to 8 months to regrow).
