How should hair be treated to remove lice? - briefly
Use an approved lice‑killing shampoo or lotion, apply it according to the label, then comb the hair thoroughly with a fine‑toothed nit comb to remove dead insects and eggs; repeat the treatment after 7–10 days to eliminate any newly hatched lice. Ensure the hair remains dry during treatment and wash all bedding and clothing in hot water to prevent re‑infestation.
How should hair be treated to remove lice? - in detail
Effective lice eradication from hair requires a systematic approach that combines thorough inspection, mechanical removal, appropriate topical agents, and post‑treatment hygiene.
Begin with a complete visual assessment. Separate the scalp into sections, using a fine‑toothed lice comb on dry hair. Move the comb from the scalp outward, cleaning each stroke on a white surface to detect live insects and nits. Repeat the process every 2–3 days for two weeks to capture newly hatched lice.
When mechanical removal proves insufficient, apply a licensed pediculicide. Choose a product containing dimethicone, ivermectin, or a pyrethrin‑piperonyl butoxide combination, following label directions precisely. Apply the solution to saturated hair, ensuring coverage to the roots and tips. Leave the preparation on for the recommended duration, then rinse thoroughly. Avoid excessive exposure by limiting use to the prescribed number of applications, typically two treatments spaced 7–10 days apart.
For individuals preferring non‑chemical options, a hot oil treatment can suffocate insects. Heat a suitable oil (e.g., olive or coconut) to 45–50 °C, apply to the scalp, cover with a plastic cap, and maintain the temperature for 30 minutes. After cooling, comb out debris and wash the hair. This method should be followed by a standard nit‑comb routine.
After each treatment, wash all bedding, clothing, and personal items in hot water (≥60 °C) or seal them in a plastic bag for two weeks to prevent re‑infestation. Vacuum carpets and upholstered furniture, focusing on areas where the head rested.
Maintain scalp health by avoiding harsh shampoos or frequent bleaching, which can weaken hair and irritate the skin. Use a gentle, pH‑balanced cleanser and condition regularly to keep strands pliable for effective combing.
Document treatment dates, monitor for live lice, and repeat the nit‑comb process until no insects are observed for three consecutive examinations. This disciplined regimen ensures complete elimination and reduces the likelihood of recurrence.
