How should I treat the head for fleas? - in detail
Treating a flea‑infested scalp requires a systematic approach that eliminates adult insects, immature stages, and prevents re‑infestation.
First, remove visible fleas and eggs. Use a fine‑toothed comb on damp hair, working from the scalp outward. After each pass, wipe the comb on a paper towel and discard it. This mechanical removal reduces the immediate parasite load.
Second, apply a topical insecticide approved for scalp use. Products containing permethrin (1 %) or pyrethrins combined with piperonyl‑butoxide are effective. Follow the manufacturer’s instructions precisely: apply the solution to dry hair, massage gently into the scalp, leave for the recommended period (usually 10–15 minutes), then rinse thoroughly with lukewarm water. Repeat the treatment after 7 days to target newly hatched larvae.
Third, administer an oral systemic agent if topical options are insufficient. Ivermectin, dosed at 200 µg/kg body weight, eliminates fleas throughout the body, including the scalp. A single dose is usually adequate; a second dose after 48 hours addresses any surviving insects. Prescription and dosage verification by a veterinarian or medical professional are mandatory.
Fourth, cleanse the environment. Wash all bedding, towels, and clothing in hot water (> 60 °C) and dry on high heat. Vacuum carpets, upholstery, and floor surfaces, discarding the vacuum bag or cleaning the canister immediately. Treat the living area with a residual insecticide spray that contains an active ingredient different from the one used on the scalp to avoid resistance.
Fifth, implement preventive measures. Use a monthly preventative shampoo or a flea‑combing routine to detect early infestations. Maintain regular grooming and inspect the scalp after outdoor activities where flea exposure is likely.
The combined use of mechanical removal, topical and systemic treatments, environmental decontamination, and ongoing prevention provides comprehensive control of fleas on the head.
