For head lice, a 1% permethrin lotion or cream rinse is typically used. It is applied to washed and towel-dried hair, left on for 10 minutes, and then rinsed off. For scabies, a 5% permethrin cream is used. It is applied to the entire body from the neck down and left on for 8 to 14 hours before washing off. It’s crucial to follow the instructions provided by healthcare professionals.
