How can you get rid of head lice with shampoo? - briefly
Apply a lice‑killing shampoo containing an approved insecticide (e.g., permethrin or pyrethrin), massage it into the scalp, leave it on for the recommended time, then rinse and comb out nits with a fine‑toothed comb; repeat the treatment after 7–10 days to eliminate any newly hatched lice.
How can you get rid of head lice with shampoo? - in detail
To eradicate head lice using a shampoo, follow a systematic protocol that combines chemical treatment, mechanical removal, and environmental control.
Begin with a product that contains an approved pediculicide, such as 1% permethrin, 0.5% pyrethrin, or a dimethicone‑based formula. Verify that the label indicates efficacy against both lice and nits. Apply the shampoo to dry hair, saturating the scalp and roots. Massage gently for the duration specified on the packaging—typically 10 minutes—to ensure the active ingredient contacts all insects.
Rinse thoroughly with lukewarm water. While the hair remains wet, use a fine‑toothed lice comb to remove live lice and detached eggs. Work from the scalp outward, cleaning the comb after each pass with a disposable wipe or hot water. Repeat combing at least three times during the initial session to capture hidden nits.
Allow the treated hair to air dry; do not use heat styling devices, which can reduce the residual effect of the shampoo. After 7–10 days, repeat the entire process with the same shampoo to eliminate any newly hatched lice that survived the first treatment. A third application, spaced another 7 days later, is advisable in severe infestations.
Simultaneously, decontaminate personal items:
- Wash all bedding, towels, and clothing worn in the previous 48 hours in hot water (≥ 60 °C) and dry on high heat.
- Seal non‑washable items in a sealed plastic bag for two weeks.
- Vacuum carpets, upholstered furniture, and car seats; discard vacuum bags immediately.
Avoid sharing combs, hats, or hair accessories throughout the treatment period. Monitor the scalp daily; the absence of live lice after the second treatment confirms success. If live insects persist after three cycles, consult a healthcare professional for alternative prescription options.
