The infested areas should be washed and towel dried. The instructions on the pediculicide should be read and carefully followed. The pubic hair and other infested areas (excluding eyebrows and eyelashes) should be thoroughly saturated with the pediculicide. After leaving on the pediculicide for the recommended time, it should be removed according to the package instructions. Clean clothing and underwear should be put on after treatment. Towels, clothing, and bedding used within the 2-3 days before treatment should be machine-washed in water of at least 130°F and dried in a hot dryer. [13] Items that cannot be laundered should be dry-cleaned or stored in a sealed plastic bag for 2 weeks. [13]
