I am astounded by how little people talk about shaving, considering it's an activity that most of the people in our culture carry out on a regular basis. My tips:

• Seconding SilasBarta's suggestion on just using warm water rather than shaving foam

• Try shaving while actually in the shower, since the humidity helps a lot

• Find an optimal frequency for shaving. (I have a magical shaving period of about 50 hours, at which my facial hair is long enough for a razor to gain easy purchase but not so long to need a lawnmower. I have pretty fair hair, though, so I can get away with only shaving every two days)

• Get some sort of post-shave moisturising product.
