I shave my head every day, sometimes twice a day, and while I've done it with DE, SE and injectors it just takes way more time than I want to invest in my noggin. Most days I use a Personna Magnum M5 but also use a Mach 3, Trac II, and the new Wilkinson Tech 3. I shave my head after my face so I use whatever soap and brush I used on my face. Occasionally I shave my head in the shower and then I use either Headslick or Real Shaving Company cream.
My scalp can take more abuse than my face and I don't ever have any issues with bumps or irritation from the cartridges.
