Using conditioner in your kids hair, then bonecombing, maybe two or three times a week, is the most effective way to treat headlice.
The pharmacy treatments of headlice are too irritating on the scalp and should only be used rarely.
But as this problem, (healice), occurs frequently, it really is better to go with the hair conditioner, and get your kids into the habit of using it when they bathe. They don't have to use a shampoo beforehand.Most young kids are put off by shampooing as it gets in their eyes, so this can be limited to a once weekly useage.
