What should be done if fleas are on the head? - in detail
If the scalp becomes infested with fleas, immediate action is required to eliminate the parasites and prevent secondary skin irritation.
First, isolate the affected individual to reduce the risk of spreading the insects to other persons or pets. Remove any headwear, scarves, or hair accessories and place them in a sealed plastic bag for at least 48 hours to kill any hidden fleas.
Second, conduct a thorough cleansing of the hair and scalp. Use a medicated shampoo containing pyrethrins, permethrin, or another approved ectoparasiticide. Apply the product according to the label, allowing it to remain on the skin for the stipulated contact time before rinsing. Repeat the treatment after 7–10 days to address any newly hatched fleas.
Third, treat the surrounding environment. Vacuum carpets, upholstery, and bedding; discard the vacuum bag or empty the canister into a sealed container. Wash all linens, pillowcases, and clothing in hot water (≥ 60 °C) and tumble‑dry on high heat. For persistent infestations, apply a residual insecticide spray to flooring and baseboards, following safety guidelines.
Fourth, monitor for signs of allergic reaction or infection. Redness, swelling, or pus may indicate secondary bacterial involvement; seek medical evaluation if these symptoms appear.
Finally, implement preventive measures. Regularly groom pets with veterinarian‑approved flea control products, maintain clean living spaces, and schedule periodic inspections of hair and scalp, especially after contact with animals or outdoor environments.
