So I've been using the DE my wife got me for Christmas and I'm having all kinds of irritation on my neck. This isn't a new thing since it has happened since my first ever shave.

So my question is this: is there an alum block recommended for sensitive skin? I read that it could help. I use Nivea sensitive skin aftershave but it doesn't do anything about the irritating bumps after the shave. Any input is greatly appreciated.
