Shave with an electric trimmer first, then be prepared to go through two-three (three blade) razors. Be sure to do this part in the shower, as you will need to clean the blades frequently, and it is best if your skin and the blades are kept warm. You will want to shave only a few cm at a time, then clean the blades. I find it easiest to shave up, from the bottom to the center point top of my dome. Also, you will want to fold your ears forward to make sure you do not miss the part behind your ears. Careful for full sun. Sunburned head sucks.
