Ehh.. Its possible. I don' tknow .. most skin pieces I have seen look very uniform like a machine just does it. I can't see why injecting or doing anything with skin would be any more challenging. THe machines probably punch the hairs right through very fast.

The only thing I can think of is factories sell cheaper in bulk. I don't think skin is as popular and they probably get only 1/4th the orders or something.
