How long can you have lice before showing symptoms?
3 doctors weighed in across 2 answers
Weeks: Head lice can live up to 30 days on a human and heir eggs can live for more than 2 weeks, so that is why it is so hard to get rid of lice. Symptoms can include intense itching of the scalp and visible lice and nets at the hair shaft. Fortunately, although a nuisance, lice do not transmit infectious diseases.
