Does Nix continue to kill lice after treatment?

Is it normal to find live lice after treatment?

Can you get lice by sitting next to someone?
You can get head lice from sitting at a desk next to someone who is infested with head lice. Head lice are spread through direct head-to-head contact. The lice do not hop, jump, or fly, so sitting near someone with head lice does not increase the risk of getting the lice.
Do dead lice fall out of hair?
But unfortunately, the nits will not simply fall out. The lice themselves take 7 to 11 days to hatch, so after that what is attached to the hair is the empty eggshell or the dead nit. These will stay attached to the hair and as the hair grows you will find them further and further down the hair shaft.

Is it possible to only have 1 lice?
Your child may have nits in his or her hair but may not develop a case of head lice. Some nits are empty eggs. However, nits that are found within 1/4 inch (6 millimeters) of the scalp typically should be treated — even if you find only one — to prevent the possibility of hatching.
At what stage is head lice contagious?

Eggs generally hatch 7 to 10 days after being laid on the hair shaft (the part of your hair closest to the scalp). The 10-day treatment period helps break the reproductive cycle of the head lice. Even if only one or two adult lice are missed, they can lay about 6 eggs per day, and the cycle of outbreaks will continue.
How come adults don’t get lice?
Head lice live off human blood, and whilst they like high blood sugar levels which make children their preferred feeding ground, it doesn’t mean they won’t like adult blood. Women have more naturally higher blood sugar levels than adult men, so you see more women than men with an infestation.
