How can you remove lice and nits from long hair? - briefly
Use a fine-toothed nit comb on wet, conditioned hair, combing from scalp to ends in small sections. Apply an approved pediculicide treatment, then repeat the process after 7–10 days to eliminate any newly hatched eggs.
How can you remove lice and nits from long hair? - in detail
Treat the infestation with a systematic approach that combines chemical or natural agents, precise combing, and thorough cleaning of the environment.
Begin by selecting an appropriate pediculicide. Permethrin 1 % lotion, pyrethrin‑based spray, or dimethicone‑based product can be applied to damp hair, following the manufacturer’s instructions for exposure time. For families preferring non‑chemical options, apply a saturated mixture of olive oil, coconut oil, or a 10 % tea‑tree oil solution; allow it to coat the strands for 30 minutes before combing.
Use a fine‑toothed nit comb designed for long hair. Section the hair into manageable 2‑inch portions, secure each section with a clip, and run the comb from scalp to tip in a single, steady stroke. After each pass, wipe the comb on a white paper towel to visualize removed eggs; clean the comb with hot, soapy water after each section to prevent re‑attachment.
Repeat the combing process at least twice, spaced 7–10 days apart, to eliminate newly hatched nymphs before they mature. If the initial treatment was chemical, a second application may be required according to product guidelines.
Simultaneously, decontaminate personal items. Wash all bedding, towels, and clothing used within the previous 48 hours in hot water (≥ 60 °C) and tumble‑dry on high heat. Seal non‑washable items such as hats, hair accessories, and plush toys in airtight bags for two weeks to starve any remaining lice.
Maintain scalp hygiene during the treatment period. Avoid excessive use of styling products that can obscure the comb’s teeth. Encourage regular inspection of the hair, focusing on the nape, behind the ears, and crown, for at least four weeks after the final combing session.
Implement preventive measures: discourage head‑to‑head contact, do not share combs or hats, and educate household members about early signs of infestation. Consistent vigilance reduces the risk of recurrence in long hair.
