What is it used for?

Important: Read warnings before use Age supervision: Children 6 months to under 12 years: an adult should supervise use. Adults and children 6 months and over: use as directed. Inspect: Have another person check all household members for lice and/or nits (eggs). Use a comb or two unsharpened pencils to lift and part the hair.

Look for tiny nits near the scalp, beginning at the back of the neck and behind the ears. Examine small sections of hair (1–2 inches wide) at a time. Unlike dandruff, nits stick to the hair. Dandruff moves when lightly touched. If lice or nits are found, treat with this product. Treat: Hair and scalp must be dry before applying product.

Use the top of the cap to break the tamper seal on the tube. Apply product directly to dry hair and scalp. Wait and rinse: Leave product on hair and scalp for 10 minutes after application. Use a timer or clock. Start timing after you have completely covered your hair and scalp. After 10 minutes, rinse product completely from hair and scalp using only water.

After rinsing, dry and style as usual. Wait 24 hours before applying shampoo. After treatment: Wash hands after applying the product. Not combing is not necessary for the product to work. If desired, use a fine-tooth comb or special nit comb to remove dead lice and nits. This is a single-use product.

Discard tube after use. Do not use again on the same person for the same lice infestation without talking to a healthcare provider first. If infestation continues, see a doctor for other treatments. Machine wash any bedding and clothing used by anyone with lice. Wash at high temperature (150°F) and tumble in a hot dryer for 20 minutes.

After finishing treatment, check everyone in your family for lice after one week. Consider treatment for those who have lice.
