Head louse infestations continue to concern public health in most countries, including the most developed ones. The present recommendations are intended to inform and stress the role and impact of the different authorities, institutions, industry, and the public in controlling head lice to reduce the prevalence of this parasite. We encourage health authorities to pursue more effective methods to identify such infestations correctly and evaluate existing and new pediculicides, medical devices, louse repellents, and louse‐ and nit‐removal remedies. Pediculicides and medical devices must have verifiable claims in the instructions for use. They should be tested periodically to document current resistance levels by lice to the active ingredients and the formulated products.

Where the prevalence of lice is claimed to be epidemic, children should be periodically evaluated objectively to document the majority’s actual level. Continuing education for health providers and the general population promises to correct misinformation regarding the biology, prevention, and management of lice. Parents should regularly inspect their children for head lice and treat them as necessary. Health authorities are encouraged to eliminate policies and practices that rely upon school exclusion to reduce incidence and prevalence, e.g., the ‘no-nit policy, which lacks scientific justification and is counterproductive to children’s health and welfare.
