After my clients receive treatment, I encourage them to perform weekly head checks on their children to catch future lice outbreaks early before they become severe. I created a video showing you just what I mean by that. This is what I recommend parents do on a weekly basis. It is not thorough, something could be missed. If there is something there, it would likely be caught by the second check if not the first. I wanted to keep it simple so that it would not be an overwhelming weekly task. It is quick and easy and will keep a severe lice outbreak away.
