Wow, that is a lot of work for, "doing as little as possible". I brush my horse's mane and tail about once a month. Perhaps I should do it more often because in my opinion they're way too thick. As for washing, why would it be necessary to wash twice a week? Thanks for the great article.
Dear Galadriel, good comment. The horses in this article are in "full training" meaning that they are worked on a daily basis and shown monthly at breed- and/or sport events. The horses are 24/7 kept in show condition, that why the care seems a bit intense.
I would live to know brands of conditioners and detanglers they like. My horse has long course hair and not all products work the best.
Hosing a horse off (when it's hot, e.g.) is ok but it is so wrong to shampoo bath a horse twice a week! Their skin dries out and it looses its natural protection.
