Dematting combs are fine if you use them the way you are. It’s when you use them as an undercoat rake and go over the whole dog repeatedly that you damage the coat.

I’ve used LaserSheen on my dogs sparringly. It sheds dirt, so you will end up with dirt on your hands every time you pet the dog, but I haven’t found anything better for getting knots out. I’ve used it to de-mat a badly matted dog, then rinsed it out, because I don’t like it left on, it makes the dog slippery.
