Indications & Clinical Uses

This shampoo is used to treat head and body lice infestations. It works by targeting the nervous system of lice, causing paralysis and death. The formula is intended for external use only and helps eliminate live lice and nits from the scalp and hair. It is commonly used as part of a comprehensive lice treatment plan.

Side Effects

When applied as directed, the shampoo begins to work by paralyzing lice within minutes of application. Users may notice a reduction in itching and irritation as lice are eliminated. The formula is designed to break down the protective coating of lice, leading to their quick demise. Regular use helps prevent reinfestation.

Avoid contact with eyes, mouth, or broken skin during application. Do not use on individuals with known allergies to pyrethrum, chrysanthemums, or ragweed. Keep out of reach of children and pets. If irritation occurs, rinse thoroughly and discontinue use. Always perform a patch test before full application.

No significant drug interactions are reported with this topical treatment. However, avoid combining with other head lice treatments unless directed by a healthcare professional. Alcohol-based products may increase skin sensitivity, so use caution if applying other hair or scalp treatments simultaneously. Consult a doctor if using on infants or pregnant individuals.
