TL;DR

Head lice are common, especially in children. They spread by head-to-head contact. Treat with silicone- or oil-based products or wet combing. Repeat after 7–10 days. Check everyone in the household.

What is the difference between a nit and an egg?

A nit is a head louse egg. They're the same thing. Nits are oval, yellowish-white, and glued to hair near the scalp. Empty casings stay attached after hatching.

How do you get head lice?

Lice crawl from one head to another during close contact. They can't jump or fly. Common sources: school, sleepovers, sports, playdates. Check with a wet comb. Not sure? Check first. For hands-on help, find a clinic near you. Schools can use our resources.
