I know that Mach3 is the best blade out there. When I shave my face and my body and as smooth as a babys butt. But then the damn ingrowns start to come in! And I can only shave once a week because if I were to do it everyday or eod...my skin gets all irratated and more ingrowns keep coming out. Should I use an electrice shaver or something like this? Any suggestions would be greatly appreciated.
