Black or brown specks that move (could be mites or other parasites)
Open sores, pus, or yellow crust (sign of impetigo or infection)
Swollen lymph nodes on the neck
Fever along with scalp irritation
You’re unsure after checking—better safe than sorry!
What You Can Do Right Now:
Take a clear photo in good lighting (close-up of the hair shaft).
Try the “flick test”: Nits won’t slide off the hair; dandruff or residue will.
Check other family members—lice spread quickly.
Avoid sharing hats, brushes, or towels until you know what it is.
