Why is laser hair reduction recommended for ingrown neck hair in men?
Laser hair reduction is recommended for ingrown neck hair in men because pseudofolliculitis barbae, the formal name for the inflammatory condition caused by curly terminal hair re-entering the skin after a close shave, resolves durably only when the underlying follicle population is reduced. The four-wavelength diode laser (FDA K191321 cleared) achieves selective photothermolysis of the follicle, eliminating the curl-and-re-enter mechanism. A board-certified dermatologist performs a 4–6 session course on the anterior neck and submental region; 80–90% reduction in ingrown lesions is typically reported by session 4. The protocol is particularly effective on Fitzpatrick IV–VI skin where pseudofolliculitis is most prevalent.
