As a woman I can say with moderate certainty that the places we tend to get ingrown hairs, are generally the areas we shave and henceforth and hitherto, tend to be very sensitive areas. I actually get a recurring one in my armpit…a signal that it’s time to change the razor. I have gotten pretty good at ‘freeing” that one with a needle as the article below suggests. There are a few other methods that will help with some of those really deep, nasty ones. Whatever you do, just make sure you sterilize your implements so as to prevent an infection !
