I’ve been shaving daily for the past 35 years. I always start shaving with downward strokes on my face. After my beard became thicker, I added shaving upstrokes and even diagonal strokes to get a truly smooth shave.
I remember several years ago when the television show, Queer Eye for the Straight Guy was on, that they always advised just shaving down strokes, and not doing anything else. IIRC, they said using upstrokes irritated the skin.
So what is the straight dope on shaving techniques? What do you do?
