Human shampoos are fine for yorkies. The only problem is they sting their eyes unlike dog shampoo so just be careful not to get it in their eyes. It might be possible to brush out the matts while the dog is wet and soaking in conditioner. I'd give it a try before giving up and cutting him short, although if it doesn't help continue to brush him daily until the grooming appointment because the tighter those matts get the shorter he will have to be cut.
