In brief: Yes!
Lice are small insects that live in hair and nest there.
The eggs can hatch later even if shampoo has killed all the live bugs. Even if you have eliminated them from the hair, others can always re-infest if you come into contact with clothing, hats, combs, or other people who are still infested. It's important to wash all clothes, bedding, and other items that the whole family has used as well.
