There is something we used to use to grow hair back on our show horses when they had a scar, or a thin tail. On the thin tail, we used listerine. My uncle, a detist, once told me that listerine will grow hair on your tongue. I thought he was joking until I started using it on horse tails. But in that case it kills the bacteria or fungus or whatever and possibly somehow stimulates hair growth.
The second thing really does grow hair and I know people who use it, it is an herbal wound solution called Schreiners Herbal solution and their website has testimonials to hair regrowth. i have been able to regrow hair on horses that have not had hair inthe area for years, sometimes it grows back twice as long in that area when it first grows in and you have to trim it to match, it works that well. Once it grows in you can stop using it on the horse and it will be fixed and keep growing hair. Its weird stuff becaue it only has a few seemingly benign herbs in it, but it definitely grows hair.
