Confirm what you see
Look for live crawling lice or nits firmly attached close to the scalp, especially behind the ears and near the neckline.
From confirming what you see to completing treatment and household follow-up, this parent-friendly guide keeps the next steps practical.
Head lice are manageable. The process begins with confirming an active infestation, using one appropriate treatment exactly as labeled and completing a focused follow-up.
Look for live crawling lice or nits firmly attached close to the scalp, especially behind the ears and near the neckline.
Read the full label, respect the minimum age and complete every application and rinsing step in the stated order.
Check household members, address recently used items and speak with a professional before repeating a single-use treatment.
Head lice are not a cleanliness problem. Anyone can get them. They spread mainly through direct hair-to-hair contact—not because a child or household is dirty.
Finding a live crawling louse is the clearest sign of an active infestation. Use bright light and work through small sections of hair, beginning behind the ears and at the back of the neck.
| What you see | How it behaves | What parents should know |
|---|---|---|
| Live louse | Crawls through hair and avoids light | The clearest evidence of an active infestation |
| Nit near scalp | Firmly attached to one hair shaft | May support an active infestation |
| Nit farther from scalp | More than about ¼ inch from the scalp | Often hatched or no longer viable |
| Dandruff or debris | Usually moves or flakes away when touched | Commonly mistaken for nits |

Start timing after the scalp and hair have been completely covered.
Discard the opened tube and ask a professional before using it again for the same infestation.
Labeled for adults and children six months and older, with adult supervision for children under 12.
Set aside enough time to fully coat the scalp and hair before the 10-minute clock begins. Use the complete Drug Facts label as your application guide.
Hair and scalp must be completely dry before application.
Cover the scalp and hair closest to it first, then work toward the ends.
Use only what is needed for complete coverage, up to one full tube.
Start the timer only after all hair and scalp areas are covered.
Rinse completely using only water, then dry and style as usual.
Wait 24 hours before applying shampoo. Wash your hands and discard the tube.
Protect the eyes. Keep eyes tightly closed and covered during application. Do not use near the eyes or on lice in eyebrows or eyelashes. Rinse gently with water if eye contact occurs.
Check all household members and close contacts. Treat people with an active infestation and follow CDC guidance for anyone who shares a bed with an infested person.
Wash and heat-dry clothing, towels and bedding used during the two days before treatment.
Soak them in hot water of at least 130°F for 5–10 minutes.
Focus on furniture and floors where the infested person recently sat or lay.
Seal items that cannot be washed or dry-cleaned in a plastic bag for two weeks.
Skip fumigant sprays and fogs. They are unnecessary for head-lice control and can be toxic. Extensive whole-house cleaning is not needed.
Even familiar lice treatments can have different directions. Review the exact package every time.
Do not use topical ivermectin 0.5% on a child under six months.
For external use on the scalp only. Keep away from eyes and other sensitive areas.

Stop use and ask a doctor if breathing difficulty, a rash, ongoing eye irritation, continued scalp irritation or infection occurs. This overview does not replace the complete Drug Facts label.
Still sorting out the next step? These are common questions parents ask before and after treatment.
No. Head lice crawl and spread primarily through direct hair-to-hair contact.
No. Head lice are not related to personal cleanliness or how clean a home is.
Nits are firmly attached to individual hair shafts and do not brush away easily. Dandruff and debris usually move or flake away.
Everyone should be checked, but medication is not automatically needed for every person. Treat active infestations and follow current guidance for bed-sharing contacts.
No. Current labeling says nit combing is not necessary for ivermectin 0.5% lotion to work, although a nit comb may be used to remove dead lice and nits if desired.
It is a single-use product. Do not use it again for the same infestation without speaking with a healthcare professional.
No. Rinse the lotion with water, then wait 24 hours before applying shampoo.
CDC guidance says a child may return after beginning appropriate treatment. Nits can remain after successful treatment, so a child does not need to be completely nit-free.
