I've heard people say that it might take a while for the face to become "conditioned to shaving" (any type of shaving). I've read it from electric shavers needing a month to condition. I've also read the same with DE blade razors.

Why? What's going on with the "conditioning"? Is something happening to the skin/hair? Is the skin or hair being "trained"? What is it? Is the skin/hair changing?

Thanks,
Jake
