How should the head be treated with chervil water for lice? - briefly
Prepare a decoction by steeping fresh chervil leaves in boiling water, allow it to cool to lukewarm, then saturate the scalp and hair, cover with a shower cap for 30 minutes, and rinse with warm water. Repeat the process every three days for two weeks to eliminate the infestation.
How should the head be treated with chervil water for lice? - in detail
Prepare a fresh chervil decoction: rinse 30 g of clean, chopped chervil leaves in 1 L of cold water, bring to a boil, simmer for 10 minutes, then let cool to lukewarm. Strain thoroughly to remove plant material; the liquid must remain clear.
Apply the liquid to the hair and scalp while it is still warm enough to penetrate the hair shaft but not so hot as to cause burns. Use a spray bottle or a cup to saturate the entire scalp, ensuring that each hair strand is coated. Massage gently for 30 seconds to distribute the solution evenly.
Cover the head with a waterproof cap or plastic wrap to retain moisture. Leave the treatment in place for 45–60 minutes. During this period, the aromatic compounds in chervil act as a mild insecticidal agent, disrupting the nymphal development of the parasites.
After the exposure time, rinse the hair with warm water followed by a mild, non‑medicated shampoo to remove residual plant matter. Dry the scalp thoroughly.
Repeat the entire procedure every 3 days for a total of three applications. This schedule aligns with the life cycle of the lice, ensuring that newly hatched insects are exposed before they can reproduce.
Precautions: perform a patch test on a small skin area 24 hours before full application to rule out allergic reactions. Avoid use on broken skin, open wounds, or in children under two years of age. Store any unused decoction in a sealed container in the refrigerator for no longer than 24 hours; discard thereafter.
