Ever since I started using a DE razor, I have gotten one or two ingrowns every other shave or so on my neck. My prep is good, I shave in the direction of growth and I only do 1 or 2 passes at most. I started using code blue after each shave but that hasn't helped. I typically don't exfoliate at all, should I do this once or twice a week after shaving? Any other typical reccomendations for this issue?
