I agree with
Black&Tan about the MSNBC link (
http://www.msnbc.msn.com/id/6886845/). Actually a pretty good article.
I'm surprised that no one else mentioned that you need a shaving brush. This has been the key for me. I used to exclusively shave against the grain and after now I get a just as a good a shave with less irritation by shaving with the grain.
If you're lazy get "The Art of Shaving" starter kit - it has a brush, oil, cream, and aftershave for $40. Also, get a cheap plastic shaving stand from the website to hold the brush upside down.
Glycerine soap (Neutrogena)
Shaving oil
Brush with Taylor's cream
Shave with the grain
Re-wet brush and apply more cream
Shave with the grain again
Any aftershave without alcohol
= smooth shave with no irritation. It really only takes a few minutes more than regular shaving, and is totally worth it.
