Rubbing alcohol has not been shown to effectively kill lice. Topical benzyl alcohol lotion, however, is prescribed to treat head lice, according to MedlinePlus. Benzyl alcohol lotion is only for use on people six months of age and older.
Benzyl alcohol lotion is classified as a pediculicide, and it requires multiple applications because it does not kill lice eggs, states MedlinePlus. The prescription amount is based on hair length and must be applied to only the scalp and hair, avoiding the eyes.
Ovide topical lotion treatments kill both lice and lice eggs, indicates WebMD. The lotion is safe for people six years of age and older and should be left on for eight to 12 hours once applied to the head. Ovide lotion is flammable, so avoid all heat sources while using it.
