TL;DR
If your child's friend has lice, check your child's hair with a fine-toothed comb. Treat only if you find live lice. Tell the friend's parents (discreetly) so they can treat. Avoid head-to-head contact until both are clear.
What do you do if you've been around someone with head lice?
Check your hair (and your child's) using the wet combing method: conditioner, fine comb, good light. Comb from roots to ends and wipe the comb on a tissue to spot lice or eggs. One live louse means treatment is needed.
How long can you have head lice without noticing?
It can take 2–4 weeks for itching to start. Some people never itch. Regular checks — especially after sleepovers or close play — help catch infestations early. Use our head lice checker for an indicative result.
