I have been shaving for a number of years. Here are a couple of suggestions. The more often you shave, the less likely the occurance of ingrown hairs. I shave every morning in the shower.

If possible, try not to shave against the grain as this encourages ingrown hairs. Use a good razor, and plenty of shaving cream or other lather to make the blade slide smoothly. It does feel great, though, doesn't it?
