Lozza, ingrown hairs are caused when the hair can't break through the skin, so it grows back in and gets yucky and gross (and kinda cool when you get them out and see how long they are... but maybe thats just me ). It tends to happen more with waxing I find as my hairs grow back a bit thinner so can't get through the skin as easy. Exfoliating when you wax/shave is essential and then every day or 2nd day after to prevent them. I am prone to them on my bikini line OUCH!!!!

If you've got them... exfoliation can REALLY hurt. What I do is use bepanthen, it helps prevent/stop any infection and also softens the skin so you can do some really gentle exfoliation to help it come through the skin. I've never tried anything specific for ingrown hairs though so don't know whether this is the best way to do it.
