How can nits and lice be removed from hair? - briefly
Apply a pediculicide shampoo, then comb wet, conditioned hair with a fine-toothed nit comb, repeating the process every few days for two weeks. Wash or seal all clothing, bedding, and personal items in hot water or airtight containers for at least 14 days.
How can nits and lice be removed from hair? - in detail
Effective elimination of head lice and their eggs requires a systematic approach that combines chemical treatment, mechanical removal, and environmental control.
A thorough chemical protocol begins with a pediculicide approved by health authorities. Apply the product according to the label, ensuring complete coverage of the scalp and hair shaft. After the recommended exposure time, rinse thoroughly. A second application, typically 7–10 days later, targets any newly hatched nits that survived the initial dose.
Mechanical removal follows the chemical step. Use a fine‑toothed nit comb, preferably metal, on wet, conditioned hair. Starting at the scalp, pull the comb through each section slowly, rinsing the comb after each pass to avoid re‑depositing eggs. Process the entire head in multiple passes until no live lice or viable nits are observed. Repeat combing daily for at least one week.
Environmental measures reduce reinfestation risk. Wash all bedding, clothing, and personal items used within the previous 48 hours in hot water (≥ 130 °F) and dry on high heat. Items that cannot be laundered should be sealed in plastic bags for two weeks. Vacuum carpets, upholstery, and car seats to remove stray hairs that may contain eggs.
For resistant infestations, consider alternative treatments such as dimethicone‑based lotions, which suffocate lice without neurotoxic action, or prescription oral agents (e.g., ivermectin) administered under medical supervision.
Monitoring continues after treatment. Inspect the scalp every 2–3 days for live insects or live nits. Persistence of any suggests treatment failure and warrants repeat of the full protocol or consultation with a healthcare professional.
