How can you get rid of fleas from the head? - in detail
Fleas on the scalp require immediate mechanical removal, chemical treatment, and environmental control.
First, isolate the affected person to prevent spreading. Use a fine-toothed comb or flea comb on dry hair, working from the scalp outward. Comb each section for two minutes, wiping the comb on a white towel after each pass to detect any insects. Dispose of collected fleas by flushing them down a toilet or sealing them in a plastic bag and discarding.
Second, apply a topical insecticide approved for human use. Products containing permethrin (1%) or pyrethrin can be sprayed directly onto the scalp, following the manufacturer’s instructions regarding dosage and exposure time. Allow the medication to remain for the recommended period, then rinse thoroughly with lukewarm water. Avoid applying excessive amounts, as irritation may occur.
Third, wash all clothing, bedding, and towels used within the past 48 hours in hot water (≥ 60 °C) and dry on high heat. Soak hair accessories, hats, and hairbrushes in a solution of water and a mild detergent, then rinse and dry completely.
Fourth, treat the living environment. Vacuum carpets, upholstered furniture, and cracks in flooring. Immediately discard the vacuum bag or empty the canister into a sealed bag. Apply a household flea spray or fogger containing an insect growth regulator (IGR) such as methoprene to inhibit egg development. Follow the product’s safety guidelines, especially regarding ventilation and pet exposure.
Fifth, monitor for reinfestation. Perform daily combing for one week, and repeat the topical treatment after seven days to target any newly hatched fleas. If itching persists, consider a prescription oral antihistamine or a short course of corticosteroid cream to reduce inflammation.
Finally, seek professional medical advice if symptoms include severe itching, rash, fever, or signs of secondary infection. A physician can prescribe stronger systemic agents, such as oral ivermectin, and assess the need for allergy testing.
