My Vie Long Horsehair brush sheds like mad. I've had it for a little over five years and it sheds just as much as when I first got it.
I might look into that. I really like the handle, so if losing more than a couple hairs every time I lather is too much for me, then I'll change the knot.The couple I had never stopped shedding.
I ended up replacing the knots with badger knots.
