As a lecturer in pharmaceutical sciences, Catherine Combescot-Lang recommends the manual method for reliable results. Use a fine-toothed metal lice comb to meticulously comb through dry or wet hair daily, targeting lice and nits. Check every family member's head weekly over a sink, and treat immediately if any are found—ideally on weekends.
Selecting the right lice product is crucial. Choose modern formulas with dimeticone or oxyphthirine, which suffocate lice. Consult your pharmacist for age-appropriate options (some unsuitable under 3 years). For shoulder-length hair like Lea's, apply half a bottle to ensure full coverage. Prioritize products that eliminate both lice and nits in one application.
Repellents have limited evidence. Traditional remedies like lavender essential oil on temples and ears or vinegar rinses lack scientific backing. Commercial preventive shampoos and lotions are often ineffective unless applied daily.
