You probably need information more than you need a professional.
Another thing I get frequently asked about is what products I endorse. While I don't have any connection to particular products, I have good things to say about effective metal lice combs such as the Licemeister and the Nit Free Terminator. But that doesn't mean that you have to have one of these combs. I also have good things to say about the generic metal, purple-handled, cheap, dual-sided comb that sells at my local Wal-Mart. It's the comb I use. If you find a metal comb that has teeth that are long, very rigid, and close together, then I'm sure it will have some effectiveness and get the job done over time.
Lice removal should be accessible, inexpensive, and easy to do. Don't think that you have to trouble yourself by ordering items from far away, travelling a long distance to get to a lice professional, or spending buckets of money on so-called "treatments". If you are not a lice expert now, you will be once you read the research and have tried a few days of wet combing. If there are services or products you want to try and you have more than enough money to spend on them, go for it. But if you are sacrificing your schedule, budget, or sanity to acquire these things, know that they aren't necessary. Your time might be better spent by grabbing the comb closest to you and getting started on that wet combing. Your money might be better spent by renting that new movie you've been wanting to see to watch while doing it.
