How can fleas be removed from a person's head? - briefly
Apply a flea‑specific shampoo or insecticidal spray to the scalp, then comb the hair with a fine‑toothed flea comb while the product is still wet. Rinse thoroughly, dry completely, and repeat the process if needed, ensuring bedding and surrounding areas are also treated to prevent re‑infestation.
How can fleas be removed from a person's head? - in detail
Fleas that have infested a human scalp require immediate and systematic removal to prevent irritation, infection, and further spread. Begin by isolating the affected individual in a well‑ventilated area and wearing disposable gloves to avoid secondary bites. Use a fine‑toothed comb or a specialized flea comb, pulling the hair taut and running the comb from the crown toward the hairline. After each pass, wipe the comb on a white paper towel; any fleas or eggs will be visible and can be discarded.
Once the mechanical extraction is complete, wash the hair with a medicated shampoo containing pyrethrins, permethrin, or another approved ectoparasiticide. Follow the product’s instructions regarding contact time, typically 5–10 minutes, then rinse thoroughly. For persistent infestations, apply a topical insecticide spray to the scalp and hair, ensuring coverage of the entire affected area while avoiding the eyes and mucous membranes. Allow the spray to dry before combing again to remove any remaining organisms.
If the scalp shows signs of inflammation, secondary bacterial infection, or if the person experiences severe itching or allergic reactions, seek medical evaluation. A physician may prescribe oral antihistamines, corticosteroids, or systemic antiparasitic medication such as ivermectin, adjusted to the patient’s weight and health status.
Finally, decontaminate the environment. Wash all bedding, clothing, and towels in hot water (≥ 60 °C) and dry on high heat. Vacuum carpets, upholstery, and pet bedding; discard the vacuum bag or clean the canister afterward. Treat pets with a veterinarian‑approved flea control product, as animals often serve as the primary reservoir for human re‑infestation. Regular grooming and environmental maintenance will reduce the risk of recurrence.
