Appears I have 3, what is the best way to remove them? Ideally easy and quick.
Also, best way to prevent them…annoying wee things!

Pick ’em out with a (sterile) needle.

Grow a beard.

Depends where they are.
If it’s neck make sure you shave with a very sharp blade, and stop using worn out blades.. diluted tea tree oil is a good lube. Don’t use it neat.

Blunt blades or hacking too vigorously without good lube are the usual cause, as it tends to pull out hair rather than cutting it.

Dig ‘em out with a Swiss Army Knife.

Rambo knife.

Chopsticks

Dildo.

And stick the vids on you tube, they serm to garner millions of views

You haven’t said where they are but I hope for your sake theyr’e not on your arse.
I’ve seen 2 hardened prisoners actually cry cos they had them on the arse!
(with one of them it was funny cos he was an orrible creature)

How do you get ingrowing hairs on yer erse in prison?

Wait until the fester and dig them out with a convieient sharp implement.

The moral being don’t shave your arse in prison.

magnesium sulphate paste. £3 in boots. bung it on, wait a day.

How do you get ingrowing hairs on yer erse in prison?

No idea, I know one of them had a dodgy follicle & ended up with a nasty boil next to his anus.* He ended up in hospital cos it got so bad.

*not witnessed by me just re-iterated by prisoner & healthcare, in case you were going to ask. Which someone would have as this place is a bit predictable.
