The eggs hatch after ten days, and the eggs are harder to kill than the bugs. So after you kill all the lice in your hair, comb out all the nits (eggs) you can find, and clean everything that might have lice or nits on them (clothes, bedding, furniture, etc.), you have to keep doing it all over again--and again--for at least ten days. Otherwise, those few nits you didn't manage to find will hatch, mate, lay more nits, and start it all over again.
