The meaning of Zero

Julian is interested in "none", "nobody", "zero" and "nothing". This is a recent conversation we had:

Julian: Scarlett only has a little hair. Mommy, does Scarlett have no hair?
Me: Scarlett does have some hair.
Julian: Who has no hair?
Me: I guess Milo has no hair.
Julian: Milo has no hair.

I remember something.

Me: Julian, you know who really has no hair? Wayne.
Julian: Yeah! Wayne has ZERO hair!
