Then use tweezers or a sterilized needle, followed by a dab of hydrogen peroxide on the area. People who find this too much of a problem might consider growing a beard. Once established, that generally solves the problem. If beards are frowned on at your work, have your physician write a note that it is a medical necessity for you to have one. Using an electric shaver is better than razors, because razors do not shave quite as close.
Razors also sharpen the hair end more, especially double track razors.
If you do use a razor, try not to shave as close. If your neck hairs are grown in different directions, train them to grow in only two directions, by only shaving up and down, and not crossways. Women should shave their legs down, not up. Shaving upward is far more likely to cause inward-growing hairs. This is because leg hairs grow downward.
