What should be done if lice appear on the head at home? - in detail
When live insects are discovered on the scalp, immediate action prevents spreading and reduces discomfort. First, isolate the affected individual to avoid contact with others, especially in shared sleeping areas. Remove clothing and bedding that may have come into contact with the hair; place these items in a sealed plastic bag for at least 48 hours or wash them in hot water (minimum 130 °F) followed by a high‑heat dryer cycle.
Next, apply a pediculicide approved for household use. Follow the product label precisely: apply the lotion or shampoo to dry hair, leave it on for the recommended duration, then rinse thoroughly. After treatment, use a fine‑toothed nit comb—spacing of 0.2 mm—to systematically comb each section of hair from the scalp to the ends. Perform this combing at least twice daily for ten days, removing any visible insects or eggs.
Clean personal items that cannot be laundered by soaking them in a solution of 0.5 % permethrin for 10 minutes, then rinse and dry. Vacuum carpets, upholstery, and car seats; discard the vacuum bag or clean the canister afterward. Seal non‑washable objects (toys, hats, scarves) in airtight containers for two weeks, the typical lifespan of a louse egg.
Monitor the scalp for a week after the initial treatment. If live insects or viable eggs persist, repeat the pediculicide application according to the manufacturer’s guidance, usually after seven days. Persistent infestation after two cycles warrants consultation with a healthcare professional for alternative medications or prescription‑strength options.
Finally, educate all household members about avoidance measures: discourage sharing of hairbrushes, hats, pillows, and enforce regular hair inspections, especially after sleepovers or school events. Consistent implementation of these steps eliminates the problem and minimizes the risk of recurrence.
