Aha... I've given up trying to stay hair free during shedding season. No matter what I do, I get hair, everywhere. Always. Even when Im riding all the loose hairs will blow back on me, in my face, in my shirt, all over my clothes, in all the hard to reach places on my saddle. Everywhere you think horse hair could never reach, it WILL reach their. I just use a shedding blade, a Slick n Easy block, and a rubber curry, and if Im feeling adventurous I will use a vaccumm.
I second the furminator! I do dog grooming and got them for grooming them but also have a large one for the horses. You don't have to buy that giant size for horses, I use a size large dog one and it works really well, just a bit more work for me. I find it gets in the smaller areas better though. Plus they are also slightly cheaper. Some people complain that you constantly have to push the button to get the hair off the blade but I find that if you do it quickly and kinda flick it slightly after you swipe it over the horse, most the hair will fall off on its own. I've been doing my guys once a week and its been helping a ton!
