Professional Head Lice Treatment Seattle — One Visit, Pesticide-Free, At Home
Our TreatmentMost lice treatment options — drugstore shampoos, prescriptions, hours of combing — require multiple rounds, kill some lice but not the eggs, or fail outright against super-lice. Our heated-air method eliminates lice and nits in a single visit, with no pesticides and no follow-up homework.
How Heated-Air Lice Treatment Works — Seattle In-Home & Renton Clinic
The method
Most lice treatments target adult lice with chemical pesticides — the same active ingredients that have been used for decades. Over time, lice have developed resistance, which is why “super-lice” are now common across the U.S. and OTC products often fail.
Heated air works on a completely different principle: it dehydrates both lice and their eggs. Lice and nits can't develop resistance to dehydration. The device delivers controlled, gentle warm air through specialized applicators that part the hair and reach the scalp directly — the same place lice and viable nits live.
After the heat step, our technicians do a thorough comb-out to remove the dead lice and loosened nits. The result: most families finish in one visit and leave non-contagious. No second appointment. No follow-up combing at home. No pesticides on your child's scalp.
Our 4-Step Seattle Lice Treatment Process
What to expectA trained technician does a thorough wet check using oil to immobilize bugs — significantly more accurate than a dry visual inspection. We show you any evidence of lice or nits before treatment begins.
Controlled heated air dehydrates lice and eggs at the scalp. Less painful than aggressive combing, more effective at killing eggs, and only one appointment required.
You leave knowing exactly what to do at home (hint: a lot less than you've heard) and how to avoid reinfestation. We answer every question you have.
The only 60-day guarantee in the nation that covers both treatment failure and reinfestation. If lice come back within 60 days for any reason, we re-treat free. See terms →

What to Expect From Your Seattle Lice Treatment Appointment
Before we arriveHave everyone in the household checked. Even people who haven't shown symptoms — lice are easy to miss with the naked eye and our 60-day guarantee requires that we check all close contacts.
Pack snacks and entertainment. Treatments take 30–60 minutes per person depending on hair length. A family of four may take 1.5 to 4 hours total.
Plan to wash your hair tonight or tomorrow. Hair will feel oily after treatment from the dimethicone we use during the comb-out.
You'll get a clearance letter. Most schools, daycares, and camps accept it for same- or next-day return.
Pay with HSA, FSA, debit, credit, or cash. We provide a receipt you can use to request out-of-network insurance reimbursement.
