Depends a lot on your skin. I don't shave my head, but I'll not infrequently get little nicks when shaving my face, despite trying all manner of razors, gels, and creams. Best is if I can give it a few days between each shave -- it tends to be much worse if I have to shave on consecutive days, as it's still irritated from one day when shaving the next.
