How to use tar soap for lice? - briefly
Apply the tar‑based soap directly to the affected scalp area, massage gently, leave it on for the recommended duration (usually 5–10 minutes), then rinse thoroughly; repeat the treatment once daily for seven days. Ensure the hair is washed with a mild shampoo after each application to remove residues.
How to use tar soap for lice? - in detail
Tar‑based soap provides a direct method for eliminating head‑lice infestations. The product combines the insecticidal properties of coal‑tar with the cleansing action of soap, allowing contact with the parasite while minimizing the need for separate rinses.
Preparation
• Choose a soap that lists coal‑tar or tar as an active ingredient, with a concentration of 2–5 % for optimal efficacy.
• Verify that the formulation is intended for scalp use and is free of harsh detergents that could irritate the skin.
Application procedure
- Wet the hair and scalp thoroughly with lukewarm water.
- Dispense a generous amount of the tar soap into the palm; the quantity should be sufficient to cover the entire scalp when massaged.
- Work the soap into a rich lather, ensuring contact with hair shafts and the skin surface.
- Massage the lather for 5–7 minutes, focusing on the nape, behind the ears, and any areas where lice are commonly found.
- Allow the product to remain on the scalp for an additional 5 minutes; this dwell time permits the tar component to penetrate the exoskeleton of the insects.
- Rinse the hair completely with warm water, removing all residues.
Post‑treatment measures
• Repeat the process after 7–10 days to target any newly hatched nymphs, as tar soap does not affect eggs.
• Comb the hair with a fine‑toothed lice comb after each application to physically remove dead insects and eggs.
• Launder bedding, clothing, and personal items in hot water (≥ 60 °C) or seal them in plastic bags for 48 hours to prevent reinfestation.
Safety considerations
• Perform a patch test on a small skin area 24 hours before full application to detect possible allergic reactions.
• Avoid contact with eyes; if irritation occurs, rinse immediately with plenty of water.
• Do not use on children under 2 years of age or on compromised scalp conditions without medical advice.
Effectiveness depends on correct dosage, thorough coverage, and adherence to the repeat‑treatment schedule. Proper execution of these steps eliminates active lice and reduces the risk of recurrence.
