Should my pcp be knowledgeable enough to look/know if my head lice is gone? with light or magnifier? i treated, continue to wet comb, still paranoid

Woods lamp for nits: If your physician has access to a Woods lamp, s/he should be able to tell if any remaining nits are alive (dead nits do not glow with a Woods lamp, live ones do). Observation of a live louse can be difficult even in active light infestations, but the presence of live nits is suggestive of a persistent infection.

Yes: Nits reflect ultraviolet light, so they are best visualized near a window or outside or better yet with a Wood’s lamp (which causes them to fluoresce). Use of a magnifying glass is also helpful.

With enough time and patience, a physician can see if there are eggs present. Possibly the best one for the task is a school nurse should you have access to one. A second treatment to attack emerging lice may be reassuring lest some be missed. There is no need to be paranoid about lice. They are treatable and not due to unsavory hygienic practices.
