TL;DR
Head lice peak when children return to school — September, after half-term, and after holidays. Close contact in classrooms and sleepovers drives spread. Check regularly and treat promptly.
Half-term holiday head lice?
After half-term, children mix with new groups at activities and playdates. Sleepovers and shared hats increase contact. A quick wet comb check when they return can catch infestations early.
Summer holiday camp head lice?
Camps and holidays bring children together for long periods. Head-to-head contact is common. Check before and after. Use silicone- or oil-based treatment or wet combing. Schools can use our school resources for guidance.
