Lice - What Happens
Lice will not go away without treatment. If the initial treatment does not kill all of the eggs (nits), a follow-up treatment may be required 7 to 10 days later to kill the newly hatched lice. Itching may last for 7 to 10 days even after successful treatment.
After treatment, dead eggs may remain in the person's hair until they are removed. Some schools have a policy of not allowing children to return to school until they are free of eggs.
If your child has lice, report it to your child's day care provider or school. Other children should be checked, so they can be treated to help prevent new and recurrent infestations.
Complications
Frequent scratching can cause mild complications such as skin infections. In severe cases, hair may fall out. Some people may develop thickened, darkened skin in areas that are infested with lice over a long period.

It’s natural to call the doctor if you think your child is sick. But do you really need to call every time? Not every sniffle is as serious as you may think.
