In brief: Not always. Depends

On pediculicide used.
The most effective approach is to retreat lice. The reason is that not all pediculicides kill the eggs. It is best to retreat in the window when the eggs have hatched into nymphs but are not yet hatching new eggs. There are however, some pediculicides which are strongly ovicidal.
