How long can dead nits stay in hair?
Nits (eggs) that are over ½ inch (1 cm) from the scalp are empty egg cases. They are very white in color. Off the scalp, nits (eggs) can’t survive over 2 weeks. Adult lice survive 3 weeks on the scalp or 24 hours off the scalp.
What if nits are still in hair after treatment?
Have the infested person put on clean clothing after treatment. If a few live lice are still found 8–12 hours after treatment, but are moving more slowly than before, do not retreat. The medicine may take longer to kill all the lice. Comb dead and any remaining live lice out of the hair using a fine–toothed nit comb.
Can dead nits stay in your hair?
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. They can stay there to the very end.
How do you keep lice eggs from hatching?
The only way to prevent them from hatching would be to remove them with a good metal nit comb, or your fingertips. Nits are laid by the mother and attached with a glue she formulates, to sit on the hair shaft. The glue is so strong that they won’t simply fall off; they have to physically be removed!
Does a nit comb get rid of eggs?
The first combing session should remove all hatched head lice but does not remove eggs. Therefore, lice that hatch from eggs after the first session may still be present. Subsequent sessions clear newly hatched lice.

How do you remove lice nits from hair?
To remove lice and nits by hand, use a fine-tooth comb on wet, conditioned hair every 3–4 days for 3 weeks after the last live louse was seen. Go through small sections of hair at a time. Wetting the hair temporarily stops the lice from moving, and the conditioner makes it easier to get a comb through the hair.
Can head lice turn into body lice?
In addition, fieldwork has shown that, in populations living in extreme poverty, the proliferation of head lice led to the emergence of lice able to adapt to clothes and turn into body lice. These body lice were then able to cause epidemics of body lice and bacterial epidemics.
