For head lice, confirm live lice, treat with proven pediculicide or wet combing, then recheck and comb every 2–3 days for two weeks.
Head lice are common and stressful, but fixable. This guide gives you a clean, step-by-step plan that matches current medical guidance. You’ll check the scalp the right way, choose a treatment that fits your situation, and keep spread to a minimum without overcleaning the house.
What To Do About Lice On Head: First 10 Minutes
Start with light, steady work. Sit near a window or bright lamp. Part the hair in small sections. Look for live, moving lice and tiny oval eggs (nits) stuck near the base of the hair, especially at the nape and behind the ears. Use a fine-tooth lice comb on damp, conditioned hair to confirm. If you see live lice, plan to treat today. If you only see shells far from the scalp, you may be seeing old, non-viable nits. A careful comb-out still helps.
Head Lice Treatments At A Glance
This table shows proven options, who they suit, and key notes so you can pick fast. Always follow the exact label for your product.
| Option | Who / Minimum Age | How It Works & Notes |
|---|---|---|
| Permethrin 1% lotion/rinse | ≥2 months | Neurotoxic to lice; some regions show lower success. Often needs a second dose day 9–10; combing helps. |
| Pyrethrins + piperonyl butoxide | ≥2 years | Kills live lice, not eggs. Repeat in 9–10 days; resistance can reduce results; avoid in ragweed allergy. |
| Dimethicone (various %) | Check label | Coats/suffocates lice. Non-insecticidal; good when resistance is common. Usually repeated once; combing aids removal. |
| Spinosad 0.9% topical | ≥6 months | Ovicidal and pediculicidal. Often one treatment; nit combing not required but still fine to do. |
| Ivermectin 0.5% topical | ≥6 months | Paralyzes newly hatched lice; often single use; no nit combing required for effect, though it can tidy the hair. |
| Malathion 0.5% lotion | ≥6 years | Ovicidal; flammable until dry. Air-dry away from heat. Often one treatment; repeat only if live lice seen. |
| Benzyl alcohol 5% lotion | ≥6 months | Suffocation method; not ovicidal. Repeat in 7–9 days. Can sting on broken skin. |
| Wet combing only | All ages | Mechanically removes lice and eggs. Free of drugs; needs a set schedule and patience. |
Dealing With Lice On The Head: Step-By-Step Plan
1) Confirm Live Lice Fast
Dampen the hair and add a dollop of conditioner. This slows lice so the comb can grab them. Use a metal or high-quality plastic nit comb. Comb from scalp to tip with tight, overlapping strokes. Wipe the comb on a white tissue after each pass. If you collect live lice, pick a treatment today.
2) Pick A Treatment That Fits Your Case
Match the product to age, cost, and local success. In many areas, spinosad or topical ivermectin end the cycle quickly. Permethrin or pyrethrins can still work where resistance is lower, but many families switch to a non-insecticidal option like dimethicone if the first round fails. If you prefer drug-free care, choose the wet-combing path and stick to the schedule.
3) Apply With Care
Use enough product to soak the scalp and the first 1–2 inches of hair. Time the application with a clock. Rinse over a sink, not a tub, to keep it off the body. Change shirts and wash hands. If the label calls for a second dose, set a reminder now so you don’t miss the window.
4) Comb, Then Recheck
Even when a medicine says nit combing isn’t required, many parents still comb to clear debris and spot late hatchers. Recheck every 2–3 days for two weeks. If you see new crawlers after the retreatment window, switch to a different class (for instance, from a pyrethroid to spinosad or dimethicone).
Wet Combing Method That Actually Works
Tools
Fine-tooth lice comb, bright light, regular conditioner, clips, white paper towel, and patience. Coat the hair with conditioner and detangle first.
Technique
Work in small sections. Comb from scalp to tip. Wipe on the towel after each pass and look for specks or moving lice. Rinse the comb often. Plan repeat sessions on days 1, 5, 9, and 13. Add a final check around day 17. This cadence catches late hatchers and keeps the count dropping.
Smart Home Care (No Deep Clean Needed)
Lice live on heads, not on couches. Do a light clean to cut down on re-exposure without turning the house upside down. Wash pillowcases, hats, hair ties, and recent bedding in hot water and high heat. Soak combs and clips in hot water for 5–10 minutes. For items you can’t wash, seal in a bag for 48 hours or set aside in a closet for two days. Skip bug bombs and furniture sprays.
Home Cleaning Checklist For Head Lice
| Task | When | Why |
|---|---|---|
| Wash pillowcases and recent bedding | Day 1, then as usual | Removes stray lice that fell off during sleep. |
| Hot-water soak for combs/brushes | Day 1 for 5–10 minutes | Heat disables lice on grooming tools. |
| Wash hats, scarves, hair ties | Day 1 | Targets items with scalp contact. |
| Vacuum sofa and car headrests | Day 1 | Quick sweep for peace of mind; no chemicals. |
| Bag unwashable items | 48 hours | Lice off a head don’t live long; two days is enough. |
| Skip room sprays and foggers | Always | No benefit for head lice; adds fumes and cost. |
| Recheck heads | Every 2–3 days × 2 weeks | Catches late hatchers before they lay eggs. |
When To Switch Products Or See A Clinician
Switch products if you still see live lice two days after a second, on-label dose, or sooner if you followed steps perfectly and new crawlers keep turning up. Choose a different class than the one you used before. Reach out to your child’s doctor if the scalp is very irritated, there are signs of a skin infection from scratching, your child is under six months, you’re pregnant, or you’re managing asthma or severe eczema and need a gentler approach.
School, Sports, And Playdates
No-nit bans keep kids out of school without improving spread. Once treatment starts and live lice are gone, most kids can return the same day. Tell close contacts and the school nurse so others can check at home. Avoid head-to-head contact during play for the first few days and don’t share brushes or hats.
Common Mistakes That Keep Lice Around
- Under-applying the product. Hair and scalp must be fully coated.
- Rinsing too soon. Time the application down to the minute.
- Skipping the second dose when the label calls for it.
- Reusing the same class after a clear failure.
- Stopping checks. Keep checking every 2–3 days for two weeks.
- Overcleaning the house. Light laundry and tool care are enough.
- Using kerosene, gasoline, or strong solvents. These are unsafe.
Medicine Details You’ll Want Handy
Spinosad 0.9%
Often a one-and-done option. It kills live lice and many eggs. A second round is only needed if live lice show up a week later.
Ivermectin 0.5% Topical
Single application in most cases. Paralyzes hatchlings so the cycle stops. Many families still do a light comb-out to clear debris.
Malathion 0.5% Lotion
Active on eggs and live lice. Let it air-dry away from flames or heat until fully dry. Repeat only if live lice persist.
Benzyl Alcohol 5% Lotion
Smothers lice rather than poisoning them. Since it doesn’t kill eggs, plan a second dose on day 7–9.
Permethrin 1% And Pyrethrins
Still useful in some places, but many regions report lower success. If live lice remain after an on-label retreatment, switch classes instead of repeating the same one again.
Drug-Free Route: Wet Combing Schedule
Wet-combing works when you stick to the calendar. Session one is the heavy lift. Session two mops up late hatchers. Sessions three and four keep the count moving toward zero. Add a final scalp check a few days later. Keep hair pulled back during this stretch and avoid sharing hair gear.
What You Can Skip
- Shaving the head. Not needed for success.
- Oils and pantry mixes as sole therapy. Results are shaky.
- Bug bombs and furniture sprays. Head lice don’t live on rugs.
- Daily sheet changes. Normal laundry is fine after day one.
Share The Plan With Everyone At Home
Tell siblings and caregivers what to watch for and how to comb. Align on the retreatment day before you put the bottle away. A shared plan keeps re-exposure from bouncing back and forth.
Trusted Guidance You Can Bookmark
For product timing and retreatment windows, see the CDC lice treatment page. For parent-friendly advice on school return and stigma, the AAP head lice guidance is clear and current.
FAQ-Free Bottom Line
If you came here asking what to do about lice on head, here’s the tight version: confirm with a comb, pick a proven product or a strict wet-combing plan, treat on label, and recheck every few days for two weeks. If the first class fails after a full, timed course, switch classes. Keep laundry simple and skip room sprays.
Wrap-Up Actions You Can Take Right Now

- Light-clean the items that touch the scalp and soak combs in hot water.
- Check every 2–3 days for the next two weeks.
