TL;DR
Schools can help prevent head lice by encouraging weekly checks, sharing evidence-based information, and avoiding "no nit" policies that exclude children. Parents should check at home and treat promptly.
Checking for head lice on your child
Use the wet combing method: conditioner, fine comb, good light. Comb from roots to ends and wipe the comb on a tissue. Check weekly, especially after holidays and half-term. One live louse means treatment is needed.
Head lice school policy
Many schools no longer have "no nit" policies — they exclude children unnecessarily. Better approach: inform parents when there's an outbreak, share our school resources, and encourage treatment. Checker here. Clinics can support schools — find one. See daily check routine.
