Finally found the website.
This is why I don't bag, braid for any period of time, or use standard horse products. I don't follow everything this business suggests, but I do what's most practical for me and my time space. It was all too perfectly logical to not try.
I went about 8 or 9 months using only water on his body and tail, and it worked. He was super shiny, and his tail started to toughen up and break less.
I'm all for natural stuff, but I don't swear by it. I'd use something artificial, as I still use some man-made things, as well as fake tails. You can't change generational traits, but you can improve what you have. This plan did work for me. The only thing I've added is Coconut oil to the water thing now.
Here's the link to the tail care, as well as the full website for other grooming tips. Again, I don't do everything, because some of it just isn't practical, but a lot of it is very logical. http://luckybraids.com/edu/TallTails.pdf Horse Braiding and Grooming Articles from Ruthann
