Leave the medicine in your hair for 10 minutes, keeping your eyes closed and covered during this time. Then rinse the medicine out thoroughly with warm water.
You may also use a nit comb to remove lice eggs from the damp hair. Work on only one section of hair at a time, combing through 1- to 2-inch strands from the scalp to the ends. Rinse the nit comb often during use. Place removed nits into a sealed plastic bag and throw it into the trash to prevent re-infestation.
Check your scalp again daily to make sure all nits have been removed.
Use a second application of spinosad topical if lice are still seen 7 days after your first treatment.
For the most complete treatment of head lice and to prevent reinfection, you must treat your environment at the same time you treat your scalp.
