During a visit, my husband's uncle tried brushing him. I said, "You'll never get to the end of all that hair." He said, "No, I probably won't today, but if he got a more regular brushing, you probably would." I knew he was right. You see, I don't give my dog a thorough brushing that often. Once a month if he's lucky. But if he was brushed regularly, I know I would get to the bottom of his shedding. His hair loss is not endless. I just need to take the time needed to get it under control.
This is how it is with head lice. At first, it may seem like the job of checking, combing, picking and blowing is never ending. It will consume you for a little while, a few days, and then you may feel like (a) you can stop regularly checking and combing because you've solved the problem, or (b) you can stop checking and combing because it's all for nothing - you feel the head lice will be there forever. You are wrong on both accounts. You should keep checking and combing and even blowing every couple of days after head lice or nits have been spotted because even if you think you've beat it, you may have missed something, or, if you know that you haven't beat it, but keep going, you will beat it eventually. Don't waste your time on housecleaning - focus 99% of your energy on the scalp. Give it regular time and you CAN be completely head lice free. You can always call me if you have any questions, need some encouragement, or want some in-home assistance.
