What should I do if lice are in long hair? - in detail
When lice infest long hair, thorough removal and prevention are essential. Begin by selecting a medicated shampoo or lotion containing permethrin, pyrethrin, or dimethicone. Apply according to the product instructions, ensuring the scalp and the entire length of hair are covered. Leave the treatment on for the recommended time, then rinse completely.
While the hair is still damp, use a fine‑toothed nit comb. Section the hair into manageable strands; start at the scalp and pull the comb through to the tips. After each pass, wipe the comb on a white tissue to detect live insects or eggs. Repeat the combing process at least three times, allowing a 7‑ to 10‑day interval between sessions to capture newly hatched nymphs.
Wash all personal items that may harbor lice: pillowcases, bedding, towels, hats, hairbrushes, and combs. Use hot water (≥130 °F/54 °C) and high‑heat drying cycles, or seal items in plastic bags for two weeks if laundering is impractical. Vacuum carpets and upholstered furniture to eliminate stray nits.
Inspect close contacts—family members, classmates, caregivers—and treat any infestations simultaneously. Advise them to avoid sharing hair accessories, hats, or headrests until the problem is resolved.
Maintain a regular combing schedule for two weeks after the last treatment, checking each section of hair daily. If live lice persist after two complete treatment cycles, consult a healthcare professional for alternative prescription options.
