Will his beard grow back?

Hello, I had left my beautiful schnauzer puppy at the groomer and, when I went back, I realized that she had shaved him down completely. I understand he had knots (I tried to comb him often--I think the knots were there when I adopted him), but now I'm afraid his beautiful beard and whiskers won't grow back. I just want to know if his facial hair will return.

Thanks!
Michele
