Head lice and nits are very common in young children. They don’t have anything to do with dirty hair and are usually picked up from head-to-head contact.

The only way to be sure someone has head lice is by finding live lice or eggs.
You can do this by combing their hair with a special fine-toothed comb (detection comb). You can buy these online or at pharmacies.
How to get rid of head lice
You can treat head lice without seeing a GP.
Treat head lice as soon as you spot them. You should check everyone in the house and treat them on the same day if they have head lice.
There’s no need to keep your child off school if they have head lice.
