Even after an infested family member has been treated, for the next 10 days, check them daily for eggs. If there is evidence of new eggs or newly hatched lice, repeat the treatment.

Head checking should then become part of routine hygiene. A family head lice check once a week is a great idea. You'll need an egg removal comb, a magnifying glass and lots of light. Working through a small section at a time, comb through each person's hair, from the root down. If any live lice or eggs are found, begin treatment immediately.
