How to treat a head for fleas? - in detail
Fleas on the scalp require immediate removal, thorough cleansing, and environmental control.
First, confirm infestation by inspecting hair and skin for live insects, flea dirt (tiny black specks), or itching marks. Use a fine-toothed comb on damp hair; run the comb from the scalp outward, wiping each stroke on a white towel to reveal trapped fleas.
Second, cleanse the affected area. Apply a medicated shampoo containing pyrethrins or permethrin, following the product’s instructions for concentration and contact time. Rinse with lukewarm water, then dry the scalp completely. Repeat the wash every 48 hours for one week to break the life cycle.
Third, apply a topical antiparasitic lotion or spray approved for scalp use. Common active ingredients include spinosad or ivermectin. Apply a thin layer to the entire scalp, avoiding excessive amounts that could cause irritation. Allow the product to absorb fully before styling or covering the hair.
Fourth, treat the surrounding environment:
- Wash all bedding, hats, scarves, and hair accessories in hot water (≥ 60 °C) and dry on high heat.
- Vacuum carpets, upholstery, and vehicle seats; discard vacuum bags or clean canisters immediately.
- Use an indoor flea fogger or spray containing adulticide and larvicide, focusing on areas where the head rests (pillows, headrests).
- Consider a single dose of oral flea medication for the individual, if medically appropriate, to eliminate any residual insects that may have migrated to the body.
Fifth, monitor for recurrence. Check the scalp daily for new bites or live fleas for at least two weeks. If symptoms persist beyond this period, seek professional medical advice to rule out secondary infections or allergic reactions.
Consistent application of these steps eradicates scalp fleas, prevents re‑infestation, and restores comfort.
