I use a "man's" eletric razor it seriously does wonders. And it's not even a name brand...i think haha. It has a few different heads so you can adjust it and it can get in all the small spaces without leaving behind razor burn or nicks. Its a remmington. It looks like this: http://funadvice.com/r/155gaafggur
Going to a Electrolysis, where there are two things they can do, zap each hair (which they would be for more under the arm hair, cause that is for smaller hair spots) or laser hair removal and after 3 treatments of either one the hair doesn't grow back anymore.
Epilating, waxing, laser hair removal, intense pulse light removal.
conditioner always works well while shaving..leaving it smooth!!!
Waxing or laser removal
