Before using this product, wash your hair with conditioner-free shampoo; rinse it, and towel-dry.
Shake the bottle well. Apply enough of the product to ensure that the hair and scalp are completely covered, especially behind the ears and at the base of the neck. Typically, 25 mL to 50 mL is needed. Keep it in your hair for 10 minutes and then rinse with water. Comb your hair with a regular comb to remove tangles. Then, separate a strand of hair no wider than the nit comb and remove nits using the nit comb. Wipe off the comb and repeat until all the hair has been combed with the nit comb. Check the hair and remove nits daily for 7 days after treatment.
Do not apply permethrin cream rinse to mucous membranes (inside of mouth, nose) or near the eyes.
It is unlikely that you will need a second application. However, if you observe lice 7 days after the first treatment, repeat the process again.
Since lice infestations are spread through contact, you should make sure that your family members and sexual partner(s) are examined for lice infestation. If they are infested, they should speak to their doctor or pharmacist immediately about using this product. Also notify your child's school, daycare, or other people who have been in close contact.
To prevent reinfestation, contaminated items such as bedding, clothing, towels, and hats should be washed in hot water and dried in the dryer using the hot cycle for at least 20 minutes. If items cannot be washed and dried this way, dry-clean or seal them in a plastic bag for 2 weeks and wash normally. Combs and brushes should be soaked in hot water above 54°C or in undiluted product for 5 to 10 minutes and rinsed with hot water.
