Head lice treatment overview and key facts

  • Lice live on the scalp and feed on small amounts of blood. They don’t jump or fly.
  • Finding live, moving lice means active infestation; nits (eggs) alone don’t always mean you need to retreat.
  • Treat infested family members the same day and check close contacts.
  • Most products target live lice more than eggs, so timing and combing matter.

Head lice treatment life cycle basics and why retreatment matters

  • Eggs (nits) hatch in about 7–10 days. Many products don’t kill all eggs.
  • If your product isn’t fully ovicidal, plan a second treatment around day 9–10.
  • Combing removes eggs that survive and reduces reinfestation risk.

Our Promise

A 60-day guarantee that actually means something.

As of 1/1/2026, we’re the only service in the nation with a 60-day guarantee covering both treatment failure and reinfestation. Most clinics only cover treatment failure — because once you leave, no one can prove whether a new bug is a survivor or a fresh catch. We’d rather just fix it than argue about it.

You’re covered when

  • Everyone with lice was treated by us within the last 60 days.
  • Everyone in — or in regular contact with — your household was checked and cleared or treated by us.
  • You can show physical evidence (e.g. a dead louse), or we find one during the appointment.

How it works

If lice return within 60 days of your appointment, we provide one free retreatment — plus checks — for each person we treated the first time, at our nearest clinic.

If evidence isn’t found, we’ll need to charge for the checks. All guaranteed checks and retreatments must be completed within 24 hours of the initial free retreatment.

Seattle-area families trust Lice Charmers

Don’t take our word for it — here’s what local parents are saying.

★★★★★

“Lice Charmers are a Godsend. Especially Melanie. I was so anxious and so uncomfortable. She was knowledgeable and so kind — an expert with compassion. I personally thought the price was low compared to what they do. Don’t even try to do this on your own. The products I bought to do it myself cost me more than what they charged. Thank you Melanie.”

“Such a great place! Responded immediately and got us an appointment the next day. It’s a small spot, so you’re the only family there. Lots of toys for kiddos and the staff is so friendly and knowledgeable. Inside is welcoming and clean. Highly recommend.”

“June was very nice and she answered all of our questions. She guided us on aftercare, what to expect and how to address it. She’s very hands-on and you can see how much she loves her job. Definitely deserves a raise for a job well done. 😊”

Before You Book

What to expect & common questions

What to expect at your appointment

  • Book a clinic or in-home appointment.
  • It’s best if everyone in the household attends.
  • Pack snacks and entertainment — a family of four may take 1.5–4 hours.
  • A skilled technician performs the checks and treatment.
  • Your hair will be oily afterward, so plan accordingly.
  • Pay with HSA/FSA, card, or cash.

How long does a lice treatment appointment take?

Most lice treatment appointments take 30–60 minutes for one person, depending on hair length and density. A family of four may take 1.5–4 hours.

Does your lice treatment kill the eggs (nits)?

Yes. Our heated-air lice treatment dehydrates live lice and their eggs during the appointment, followed by a thorough comb-out to remove them.

Is your lice treatment safe for kids?

Yes. Our lice treatment uses controlled heated air and no pesticides, so it is safe for children and adults and works across most hair types.

How much does lice treatment cost?

Professional lice treatment ranges from $199 to $225 depending on hair length and density. We accept HSA/FSA, credit, debit, and cash.

Do you offer in-home lice treatment, or clinic only?

Both. You can book lice treatment at our Renton clinic or request in-home mobile lice treatment across the Seattle metro. Both use the same heated-air method and the same 60-day guarantee.

Do you guarantee your lice treatment?

Yes. Our lice treatment comes with a 60-day guarantee that covers both treatment failure and reinfestation, subject to everyone in the household being checked and cleared or treated by us.

Do I have to deep-clean my whole house after lice treatment?

No. Focus on the last 48 hours: hot-wash pillowcases and hats, soak combs in hot water, and vacuum where heads rested. Skip sprays and foggers — they add no benefit.

Do I need to treat everyone in the household?

Check all close contacts the same day and treat anyone with evidence of lice. This prevents the ping-pong reinfestation that causes most repeat cases.

What if over-the-counter lice treatment didn’t work?

Over-the-counter products often miss eggs, and many lice are now resistant to them. Our heated-air lice treatment targets both lice and eggs in a single visit, including resistant super lice.

Is your lice treatment pesticide-free?

Yes. Our lice treatment uses controlled heated air and a finishing oil, with no pesticides. This is consistent with American Academy of Pediatrics guidance favoring physical over neurotoxic methods.

Will I be lice-free and non-contagious the same day?

Yes. After your lice treatment appointment you leave lice-free and non-contagious the same day, with no chemical wait time.

Do I have to remove every nit after treatment?

No. After heated-air lice treatment and comb-out, remaining nits are dehydrated. You can remove any visible nits for cosmetic reasons, but it is not required.

Can my child return to school after lice treatment?

Yes. Because you leave non-contagious the same day, your child can return to school after lice treatment. No-nit school policies are generally discouraged, since nits alone don’t prove active infestation.

How is professional lice treatment better than DIY?

DIY lice treatment commonly fails because drugstore products don’t kill all eggs, resistant super lice survive, and one missed nit restarts the infestation. Professional lice treatment clears lice and eggs in one guaranteed visit.

Do I need a second lice treatment appointment?

No. Our lice treatment is one-and-done with no required aftercare or second paid appointment. The only return visits are guarantee checks if lice reappear within 60 days.

How do I prepare for my lice treatment appointment?

Bring everyone in the household, pack snacks and entertainment for longer family appointments, and plan for oily hair afterward. No pre-treatment products or special prep are needed.

We understand that for many families, discretion and comfort are the top priorities. Our premium mobile service brings the same technology used in our clinics directly to your living room.

  • Total Discretion — Our technicians arrive in unmarked vehicles. We respect your privacy; your neighbors won’t even know we’re there.
  • Simple Setup — We only need a small workspace near a standard power outlet. Our technicians bring all necessary equipment.
  • A Familiar Environment — Kids are often more relaxed at home. They can sit on their favorite chair and watch their own TV while we work.
  • The “Clean Sweep” — While we treat your family, we provide clear, low-stress guidance for your home. You’ll learn exactly what needs to be washed and what you can ignore.

Same “One & Done” Results — You get the exact same treatment and 60-day guarantee as our in-clinic patients. When we leave, your family is lice-free and non-contagious.

Over-the-counter: permethrin 1%

How it works: Nerve-targeting pesticide that kills live lice.
How to use: Apply to clean, towel-dried hair with no conditioner. Saturate from scalp to ends, wait per label, rinse over a sink, and comb with a fine-tooth nit comb. Recheck every 2–3 days and retreat on day 9–10 if needed.
Shortcomings: Not 100% ovicidal (eggs can survive). Some lice show resistance. Requires careful timing and thorough combing. Can feel drying or irritating.

Over-the-counter: pyrethrins with piperonyl butoxide

How it works: Plant-derived pyrethrins plus booster; kills live lice, not eggs.
How to use: Apply to dry hair per label, rinse after the set time, then nit-comb thoroughly. Always retreat around day 9–10.
Shortcomings: Not ovicidal — retreatment required. Ragweed/chrysanthemum allergy risk. Resistance is common. Multiple rounds increase effort and cost.

Prescription: spinosad 0.9%

How it works: Targets lice and many eggs; often effective with a single application.
How to use: Saturate dry scalp and hair, wait per label, rinse, and comb if you want faster cosmetic cleanup. Retreat only if live lice are seen after 7 days.
Shortcomings: Cost can be higher. May need a prescription. Oily feel and mild irritation possible. Rare retreatment still needed.

Prescription: ivermectin 0.5% lotion

How it works: Paralyzes lice and prevents survival of newly hatched lice.
How to use: Single application to dry hair; rinse after the labeled time. Combing optional but helpful for speed.
Shortcomings: Cost may be high. Age limits (typically ≥6 months). Not primarily ovicidal, so visible nits can remain. Some cases still need follow-up.

Prescription: benzyl alcohol 5%

How it works: Suffocates live lice, not eggs.
How to use: Apply to dry hair, wait per label, rinse, and nit-comb. Repeat on day 7.
Shortcomings: Always needs retreatment. Possible stinging/irritation. Can be messy and time-consuming on long or thick hair.

Prescription: malathion 0.5%

How it works: Kills lice and some eggs (partly ovicidal).
How to use: Apply to dry hair, let it air-dry for the labeled time, then rinse and comb. Repeat day 7–9 if needed.
Shortcomings: Flammable — avoid heat sources while it’s on the hair. Strong odor, longer processing time, age limits (often ≥6 years), and potential irritation.

Non-chemical: wet-combing and manual nit removal

How it works: Mechanically removes lice and eggs with a fine-tooth metal comb on wet, conditioned hair.
How to use: Comb in small sections from scalp to ends every 3–4 days for at least 2 weeks, wiping the comb on a white towel to check progress.
Shortcomings: Time-intensive and technique-dependent. Easy to miss tiny nits. Requires multiple sessions, consistent lighting, and patience.

Professional heated-air treatment (what we do)

Why it’s best: Controlled heated air dehydrates lice and eggs right on the scalp — no pesticides, and highly effective against resistant lice. Most families finish in one visit, with minimal aftercare. Works across hair types and lengths.
What it solves: Avoids chemical side effects, retreatment schedules, and days of meticulous combing. Great for busy households and repeated school exposures.

  • Focus on the last 48 hours: wash pillowcases, hats, and hair accessories in hot water and high-heat drying (≥130°F).
  • Soak combs/brushes in hot water for 10 minutes.
  • Vacuum car seats and sofas where heads rested.
  • Skip sprays and foggers — they don’t add benefit and can irritate.

School & return-to-school: Most kids can return after treatment begins. “No-nit” policies are generally discouraged because nits alone don’t prove active infestation. Tell close contacts to check and treat if needed to prevent ping-pong spread.

Ask these before booking anywhere. The answers might surprise you:

  • Do they require a second paid visit? (We don’t.)
  • Does the guarantee outlast the hatch cycle (30 days)? (Ours does — multiple times.)
  • Does the guarantee cover reinfestation? (We do.)
  • Will you leave non-contagious the same day?
  • Are you expected to comb at home afterward? (You shouldn’t be.)

HSA/FSA: We are a qualified expense.
Insurance: We provide a receipt you can use to request out-of-network reimbursement. Medicaid discounts are available with proof of coverage.
Methods: We accept credit/debit and cash, but we do not have change.
