With all of our technology you'd think somebody would have thought of a way to kill head lice. Over the past 6 weeks I think I have treated my daughter about 4 times and it's driving me crazy. Disgusting little creatures! I'm considering buying one of those electric lice combs but wondering if others had found them any good? With the lotion costing about $20 a pop I thought paying for an electric lice comb for about $50 might be worth it in the long run!
