No creams, waxes fru fru crap = no.
I use conditioner occasionally, whatever stuff my girl stocks. I don't think it's imperative.
1. Water resistant electric trimmer, to keep in check and even. Max setting of 10 (mm?) on I think a Panasonic. ~weekly
2. Upper lip, I use the same trimmer, set to 6 (mm?). Much longer, tends to get in my mouth

3. A Mach3, shave 3-4 times a week to shave my neck to avoid the itches, and to keep the edges tidy.
4. Head also gets the mach3 treatment also, twice a week

just say no to male pattern baldness.
