@ZipLine-- Are you exfoliating regularly?
I used to get a lot of ingrown hairs on my face and my neck before. Ever since I started exfoliating my skin on a regular basis, I haven't had any.
Some of us have thicker skin than others. I also have a skin condition called keratosis pilaris that causes my skin to be thick and bumpy. So I'm very prone to getting ingrown hairs.
I use an exfoliating scrub, as well as a loofah every time I shower to remove dead skin. It sounds like a very simple ingrown hair treatment, but it works.
