Vamousse Lice Defense Daily Shampoo is designed for treatment follow-up and for anyone exposed to head lice to start killing lice that may have been contracted and not yet detected. Did you know that it takes 4 - 6 weeks for itching symptoms to start? By the time a head lice infestation is identified, others have been exposed likely for weeks and may have contracted the infestation themselves (siblings, parents, friends). When there is news of an outbreak, check for lice. Lice can be very difficult to find. If you do not find any, you can still make a simple swap to a pesticide-free daily shampoo that will go to work killing any contracted lice not yet detected. Vamousse Lice Defense Daily Shampoo, made with Eucalyptus Oil, is gentle on hair but tough on lice. Use just as a regular daily shampoo, lather for 3 minutes, and rinse to begin killing lice by contact, defending against the growth of an infestation. Suggested Use: Product may be used as often as needed. Adults and Children 2 Years and Older: Apply a generous amount of shampoo to wet hair, work into a lather and massage into scalp. Leave shampoo in hair for at least 3 minutes. Rinse. For defense against a head lice infestation, use daily for at least 10 to 14 days to kill any lice that may have hatched. For an active head lice infestation, use Vamousse Lice Treatment before using this shampoo. Children Under 2 Years: Ask a doctor. UPC: 358962191626 Weight: 1 lbs RKU: WAL150916463
