Flashback to 2010: One day my nine year old said, My head itches (scratch, scratch). . .Jane Doe (friend) said she had lice last week, but it's not her fault. She got it at her cousin's house.â€ After visual confirmation, I went to Google to research which OTC brand was most effective. Couldn't find much difference between permethrin and pyrethrin, so though I hated using pesticides on her, I picked one, put on a long DVD, and got started. A couple days later, there was still a live louse. I did some more research, read lice are becoming resistant to these pesticides, and looked up the active ingredient in the expensive ($90ish a bottle) newer Rx treatment â€“ benzyl alcohol. I found its available cheaply from chem suppliers online. When looking for an emollient substrate to mix with it, I stumbled across the Nuvo (Cetaphil) Method.â€ Turns out Cetaphil Gentle skin cleanser contains cetyl alcohol which has been shown to be effective in smothering lice. Google Dr. Pearlman â€“ he's a derm who tried to formulate an exclusive lice tx to sell to his wealthy clients and used Cetaphil as the control. It worked better than his product, so he repackaged it as Nuvoâ€, and tried to make $$$$ off it. His study was published in the September 2004 issue of Pediatrics. He couldn't interest pharm companies to invest in it, so he came clean (haha) and released the Nuvo Methodâ€ using Cetaphil on the web.
My daughter already showers with Cetaphil since she has mild eczema, so I had it on hand and just switched to it for the 7 day follow up tx. I get it at Costco, or at CVS when they send out coupons. Worked great, smelled better, and left her hair soft. Still took a lot of time because you blow dry it in to shrink wrap the lice, but hey, they won't become resistant to suffocation, will they!
