You finished the lice treatment, you’re combing through your child’s hair, and the little specks are still there. Some are dead lice. Some are eggs cemented to the strands. And your stomach drops: did this even work? Here’s the calm version. Dead bugs and empty eggs don’t fall out on their own, so seeing them after treatment is expected, not a warning sign. Your child isn’t contagious from dead bugs. You don’t have to strip every speck out in one sitting. Plan on short comb-outs over the next couple of weeks, and judge the whole thing by one signal only.
That signal is live, moving lice. Stop finding those and the treatment worked; the rest is cleanup. Here in Davie, a lot of the families we see are stuck on exactly this step, staring at leftover flecks and wondering whether to run out for another bottle. Usually they don’t need one. They need a plan for getting the dead ones out and a way to be sure the head is clear.
Why Dead Lice and Nits Stay Stuck in the Hair
A live louse holds onto hair with tiny claws, and a female glues each egg to a strand with a cement-like coating that water and shampoo won’t dissolve. Kill the louse and it doesn’t suddenly let go. Treat the egg and the glue stays put. So the specks in front of you are the physical leftovers of the case, not proof it’s still alive. They come out one way, mechanically, by dragging them off the strand with a fine comb or a fingernail. Before you spend an evening on it, it helps to sort which white flecks are actually lice eggs and which are dandruff or product buildup, because you can chase lint for an hour and get nowhere.
The First Day or Two After Treatment
Right after treatment, expect the hair to still look occupied. You’ll see dead and dying lice, and plenty of eggs. That is normal. A good comb-out the same day pulls out most of the dead adults and loosens some eggs, but it won’t get everything, and that’s fine. Work in small sections under a bright light, wipe the comb on a white paper towel between passes so you can see what’s coming out, and stop when your child is done cooperating rather than forcing a marathon. Day one is about thinning the herd, not finishing the job.
The Next Two Weeks Are Where the Real Work Happens
Eggs are the reason this takes two weeks and not one night. Any egg that survived treatment can still hatch, usually within about a week, so a single comb-out never covers the whole cycle. The American Academy of Pediatrics recommends combing every two to three days for two to three weeks after treatment to catch anything that hatches late. Do it on damp hair with a little conditioner so the comb glides, part the head into sections, and pull the comb from scalp to tip in each one. It’s tedious. It’s also what clears the case, because it lifts both the dead bugs and the eggs a bottle leaves behind. Drugstore shampoo can stun or kill live lice, but it won’t remove those glued eggs. That part is always hand work.
How to Tell a Finished Case From an Active One
Here’s the line that matters. A finished case has no live, crawling lice, only stragglers you’re combing out. An active case has bugs that move. If, a week or so in, you’re still finding live lice that scurry away from the light, the first round didn’t fully take, and a second treatment timed to the hatch is a sensible call. If all you’re finding is the odd empty shell sliding down a strand, that’s just old evidence on its way out. Telling those two apart is hard to do at the kitchen table, and whether leftover eggs mean an active case or just old, hatched shells is one of the most common questions parents bring us. When you can’t tell, that uncertainty is a good reason to have someone look.
What You Handle and What We Handle
Most of the day-to-day combing is a home job, and you don’t need us for it. Where families call is the parts that are hard to do to your own child’s head, or hard to be sure about on your own.
| You handle at home | We handle in the Davie clinic |
|---|---|
| Comb-outs every few days on damp, conditioned hair | A thorough, strand-by-strand comb-out under clinical light |
| Washing pillowcases and hats worn in the last two days | Confirming which specks are live eggs, empty shells, or debris |
| Watching for live, moving lice | A non-toxic professional treatment when a live case is confirmed |
| Keeping the routine going for two weeks | A follow-up screening that tells you the head is clear |
If a home pass isn’t keeping up, or you’d rather not spend two weeks second-guessing every fleck, a professional lice treatment and comb-out does the tedious part for you and ends with a clear read on where things stand.
If the guesswork is the worst part, you can skip it. Plenty of Davie parents just book a follow-up head check and let us confirm the all-clear in a single visit instead of combing on faith for two weeks.
Get Clear Before the Classrooms Fill Back Up
There’s a clock on this one. Broward County Public Schools start the new year on Monday, August 10, 2026, with more than 236,600 students across 239 schools and centers. That’s a lot of shared classrooms, and head-to-head contact in those rooms is how a not-quite-finished case spreads to the next family.
The Florida Department of Health in Broward County runs school health services alongside the district, including screenings and communicable-disease prevention, to keep kids healthy and in class. So the goal isn’t only to get the dead ones out. It’s to be clear before day one, not still combing through the first week.
Quick recap: expect leftover dead lice and eggs for a couple of weeks, comb every two to three days, wash whatever touched the head in the last two days, and treat live, moving lice as your only pass-or-fail. The home version mostly costs you time and patience; a clinic visit trades that time for a set fee we quote up front.
Start the School Year Actually Done
If you’ve combed and combed and still can’t tell whether those specks are a problem, that’s the moment a trained set of eyes earns its keep. We’ll comb the whole head under proper light, tell you plainly whether anything alive is left, and handle it that day if it is. Schedule a clearance check for your child and head into the new year genuinely finished, not almost. It beats another two weeks of wondering.
Frequently Asked Questions
Is my child contagious with dead lice still in the hair?
No. Dead lice can’t crawl or move between heads, so they can’t spread to anyone. Only live, moving lice pass through direct head-to-head contact. Once you stop finding live bugs, your child isn’t a risk to classmates, even while a few dead specks and empty eggs are still working their way out of the hair.
Do I really have to remove every single nit?
Not for health reasons. Empty, hatched shells are harmless and mostly a cosmetic thing. What matters is combing out any egg close to the scalp that could still hatch, which is why the two-week routine focuses there. Older shells farther down the strand grew out with the hair and won’t restart a case.
Can my child go back to school with a few nits left?
Usually yes, but policies differ by school. Many schools now let a child attend once live lice are treated, while some still ask that visible nits be cleared first. Check your child’s school directly. Either way, finish the full comb-out at home, because a passed inspection isn’t the same as a cleared case.
I still see bugs two weeks later. What should I do?
It depends on whether they move. Live, crawling lice mean the case didn’t fully clear, and a second treatment timed to the hatch is reasonable. Dead bugs or empty shells are normal cleanup, so keep combing. When you can’t tell which you’re looking at, that uncertainty is the right moment to have a professional confirm it.
