I get HELL razor burn and ingrowing hairs by the hundred down at the collar line. So, I invested in
a top of the line PhiliShave. Hateful thing. You spend so damned long chasing individual haris that it's missed that you're in there for hours. Having said that, it's the best electric I've ever had.
So, I went back to wet shaves. Back to my trusty M3 Turbo. Now though, I only shave WITH the grain, and only every two or three days (thing George Michaels designer stubble
!!) - no more rash/ingrowers. Sweet.
