The only way to prevent head lice from moving onto your head would be to never have head-to-head contact with anyone – an unlikely situation, particularly for children. The best you can do is check for head lice on a regular basis using the detection method, carry out contact tracing if a louse is found, and don’t forget to check if you are told about an infection through contact tracing from someone else.

That way you have the opportunity to treat a head louse infection before they lay too many eggs and before it is passed on to too many others.
