Is this a result of frostbite?

We had a couple nights in west central SC where the temps got down below freezing. Is the white on his comb a residual effect of frostbite or is it something else. He is a 9 mo. old red ranger.

Looks like dry skin.

Could be some mild frostbite, but I wouldn't be worried about. It should go away on its own in a few weeks.
