What helps with lice on the head? - briefly
Effective treatment involves applying an FDA‑approved pediculicide (shampoo, lotion, or mousse) exactly as directed and then combing the hair with a fine‑toothed nit comb to eliminate live insects and eggs. Follow up by laundering bedding, clothing, and personal items in hot water and vacuuming the living area to reduce the risk of recurrence.
What helps with lice on the head? - in detail
Effective treatment of head lice requires a combination of chemical, mechanical, and environmental strategies.
Over‑the‑counter pediculicides containing permethrin (1 %) or pyrethrin with piperonyl butoxide act by disrupting the nervous system of the insects. Apply the product according to the label, leave it on the scalp for the specified time, then rinse thoroughly. A second application 7–10 days later eliminates newly hatched nymphs that survived the first dose.
Prescription options include benzyl alcohol lotion (5 %), ivermectin (0.5 % lotion), and malathion (0.5 %). These agents are reserved for cases where resistance to first‑line treatments is documented.
Mechanical removal complements chemical agents. Use a fine‑toothed lice comb on wet, conditioned hair. Process each section from scalp to tip, cleaning the comb with hot water after each pass. Repeat combing every 2–3 days for at least two weeks.
Environmental measures reduce re‑infestation. Wash bedding, hats, and clothing in hot water (≥ 55 °C) and dry on high heat for 30 minutes. Items that cannot be laundered should be sealed in a plastic bag for two weeks. Vacuum carpets and upholstered furniture to remove stray nits.
Adjunctive practices enhance efficacy:
- Trim or shave hair to shorten the length, making combing easier.
- Avoid the use of hair sprays, gels, or oily products during treatment, as they can interfere with pediculicide absorption.
- Educate all household members about detection and prevention to prevent cross‑contamination.
Monitoring after treatment involves inspecting the scalp daily for live insects or viable nits. Persistence of live lice after two treatment cycles warrants consultation with a healthcare professional for alternative regimens.
