Hey everyone, just a question? I shave my dome with a Fusion and/or Mach3 razor, then I will shave face, neck, and tidy-up around the ears with a Excel Sensor which works great, however, I just started to shave against the grain for the dome and am getting smooth results, but my only issue is where should you start/stop the against-the-grain shave for the dome at the sideburns area? I cannot shave against the grain at neck and face as produces ingrown hairs so am seeking that perfect seamless transition from sideburn area to dome.
