I'm a African-Carribean male who, in the past used an Wahl electric razor, which was fine. When I could no longer get a close shave I tried cartridges Mach3 razors which irritated the hell out of my face. Razor rash, and ingrown hairs. So went back to the electric. After a while, I decided to try a double edge razor and this did the trick. Not only do I get a close shave, I no longer suffer from ingrown hairs. I personally the latter is achieved by using shaving oil in combination with a good antibacterial soap!
