How and how to use tar soap for lice? - briefly

How and how to use tar soap for lice? - in detail
Tar‑based soap is employed as a topical pediculicide to eradicate head‑lice infestations. The active component, coal‑tar, possesses insecticidal properties that disrupt the nervous system of lice and their eggs. Proper application maximises efficacy while minimising skin irritation.
The treatment protocol consists of several distinct steps:
- Clean the scalp with a mild shampoo; rinse thoroughly and towel‑dry. Removing excess sebum facilitates penetration of the tar formulation.
- Apply a generous layer of the tar soap directly onto the hair and scalp, ensuring coverage of the entire hair shaft from root to tip. Use a comb to distribute the product evenly.
- Leave the soap in place for the duration specified by the manufacturer, typically 10–15 minutes. During this period, the active compounds act on both adult lice and nits.
- Rinse the hair with lukewarm water until all residue is removed. Avoid hot water, which can increase skin sensitivity.
- After drying, repeat the procedure after 7–10 days to target any newly hatched lice that survived the first application.
Additional considerations:
- Conduct a patch test on a small area of skin 24 hours before the first use to detect possible allergic reactions.
- Do not apply the soap to broken or inflamed skin; discontinue use if severe irritation occurs.
- Combine chemical treatment with mechanical removal by using a fine‑toothed nit comb at least twice daily for the first week.
- Wash bedding, clothing, and personal items in hot water (≥ 60 °C) or seal them in airtight containers for two weeks to prevent re‑infestation.
Tar soap remains a viable option when resistance to conventional pyrethroid treatments is documented. Its mode of action, topical administration, and repeat‑dose schedule provide a comprehensive approach to eliminating head‑lice populations.
