Sometimes 'effective' can also be 'inexpensive'.
Never underestimate a decent lice comb. And I'm not talking about the plastic comb that comes in the Nix package. A proper metal lice comb is an extremely wise investment as it can cut your nit picking in half. I have always recommended the Licemeister, which is a great comb, but the cost is prohibitive for some. Then a client told me about a good comb that she found at Wal-Mart - the Pharmasystems dual-sided lice comb (see the blurry picture). It is a pretty generic comb, but I tried it and have found it to be both effective and inexpensive. I bought mine at Wal-Mart for around $9. You may have to ask the pharmacist where the lice combs are located as they are not stocked beside the regular brushes and combs. I don't think this comb is as durable as the Licemeister, but it can still be boiled and is good for multiple uses. On the back of the package, it tells you to "shampoo with pediculicide". As you know, I don't think this is necessary or beneficial. Just use the comb regularly. If you want to clean out the comb between strokes, dip it in water and wipe with toilet paper or a paper towel. If you want to clean between the teeth, do not pry the teeth apart - just clean between them with dental floss.
