What to do if people have fleas in their hair? - in detail
If fleas are discovered in a person’s scalp, immediate action is essential to prevent further infestation and possible skin irritation.
First, isolate the individual from close contact with others and pets. Remove any head coverings, hats, or hair accessories that may harbor insects. Wash these items in hot water (minimum 60 °C) and dry on high heat.
Next, perform a thorough cleansing of the hair and scalp:
- Wet hair with warm water.
- Apply a medicated shampoo containing pyrethrin, permethrin, or another approved insecticide. Follow the product label for concentration and contact time.
- Massage the scalp gently to dislodge fleas and eggs.
- Rinse completely and repeat the treatment after 24 hours if instructed by the label.
After shampooing, use a fine-toothed comb (often supplied with anti‑lice kits) to comb through damp hair from root to tip. Clean the comb with hot, soapy water after each pass. This mechanical step removes remaining insects and nits.
Treat the surrounding environment to eliminate sources of re‑infestation:
- Vacuum carpets, upholstery, and bedding; discard vacuum bags or clean canisters immediately.
- Wash all bedding, towels, and clothing in hot water and dry on high heat.
- Apply an insecticide spray or powder to upholstered furniture and floor coverings, adhering to safety guidelines.
If the person experiences intense itching, redness, or signs of secondary infection, seek medical evaluation. A healthcare professional may prescribe oral antihistamines, corticosteroids, or stronger topical agents.
Finally, educate all household members on preventive measures: avoid sharing personal items, maintain regular hair hygiene, and inspect pets for fleas, treating them concurrently if necessary. Continuous monitoring for at least two weeks ensures that the infestation has been fully eradicated.
