• . Household members that have an active head lice infestation defined as: At least 1 live louse (adult and/or nymph) present on the scalp and/or hair, as determined by a trained evaluator (with the exception of the male head of household who may self-assess as being lice free) will receive the Standard of Care with an over-the-counter head lice treatment product. Up to 3 infested household members may receive treatment, if more than 3 household members are infested, the entire household will be excluded from the study.
