I've had one of those super long hairs be ingrown. It just coiled in on itself. I thought it was a black spot, so I dug it out with a sharp pair of tweezers. Once I got it and started pulling, it just kept going. Hair and puss came out and it felt terrible. Once I got it out it healed very quickly and felt much better, so I'm glad I did it, but that feeling still creeps me out.
