It'd be possible that a child get head lice from another child that is getting treated for it?

If still present: Head lice are sometimes hard to get rid of.Sometimes multiple treatments and meticulous removal of egg casings are needed before they are gone for good. If present and the child shares a sleeping mat, headgear, brush or other item they can be passed easily.It can also take 10 or more days before you pick up that your kid has them.It takes that long for new lice to start laying visable eggs.
