Been manscaping for 30+ years, gotten 3 IGHs in the vicinity of my junk, pretty evenly spaced across time.
First one, I tried treating like a ripe zit, which is a horrible idea. It got infected & took 4 months to be completely gone.
Second one, I took afro-desiac's approach, with the addendum 'disinfect tweezers, use tweezers, disinfect site'. It resisted my first couple weeks worth of effort, so I left it alone. After another month or so, something grabbable showed up & I pulled & pulled - damned thing was like 2 inches long!
Third one is a work in progress. Let the lawn grow in around it, plucked some suspects that were merely nosy neighbors. The wiki site, citing medical sources suggested long hot baths, topical analgesic creams, seeing a doctor, or just leaving it alone. The creams (and baths) supposedly make it more likely that the hair can be accessed. A doctor would use "a rotable medical device" - I don't feel enough urgency to let her poke a hole in my junk, just to get it out sooner.
