Inclusion criteria
✓. Signed Institutional Review Board (IRB)-approved informed consent form that meets all criteria of current FDA regulations. For participants who are considered minors in the state the study is being conducted (\<18 years in most states), the parent or legal guardian should sign the consent form and the child will be required to sign a participant "assent" form, as appropriate. Participants 11-17 years of age will read and sign an IRB-approved assent form and participants 6-10 years of age will provide verbal assent. Participants 6 months-5 years of age will be exempt from providing assent based on the child's comprehension and cognitive skills.
✓. The participant and/or the participant's parent (legal guardian) is willing to apply the study product as directed, comply with study instructions, and commit to all follow-up visits for the duration of the study.
✓. Male or non-pregnant, non-lactating female, 6 months of age or older.
✓. Females of childbearing potential must not be pregnant or lactating at Visit 1 (Day -1 to 1) (as confirmed by a negative urine pregnancy test with a sensitivity of less than 50 milli-international units/milliliter \[mIU/mL\] or equivalent units of human chorionic gonadotropin). Women of childbearing potential must agree to the use of a reliable method of contraception. (for example, total abstinence, intrauterine device, a double-barrier method, oral, transdermal, injected, or implanted non-hormonal or hormonal contraceptive) throughout the study. Female participants using hormonal contraceptives should have been on the same product/dosing regimen for at least 28 days before Visit 1 (Day -1 to 1) and should not change this regimen during the study. A sterile sexual partner is not considered an adequate form of birth control.
✓. Index participants (that is, the youngest household member) must have an active head lice infestation, defined as ≥3 live lice (that is, live adults and/or nymphs), at Visit 1 (Day -1 to 1).
✓. Household members participating in the study must have ≥1 live louse (that is; live adults and/or nymphs) at Visit 1 (Day -1 to 1).
