    • look for tiny nits near scalp, beginning at back of neck and behind ears
    • examine small sections of hair at a time
    • unlike dandruff which moves when touched, nits stick to the hair
    • if either lice or nits are found, treat with this product
    Treat
    • apply thoroughly to dry hair or other affected area. For head lice, first apply behind ears and to back of neck.
    • allow product to remain for 10 minutes, but no longer
    • use warm water to form a lather, shampoo, then thoroughly rinse
    • for head lice, towel dry hair and comb out tangles
    Remove lice and their eggs (nits)
    • use a fine-tooth or special lice/nit comb. Remove any remaining nits by hand (using a throw-away glove).
    • hair should remain slightly damp while removing nits
    • if hair dries during combing, dampen slightly with water
    • for head lice, part hair into sections. Do one section at a time starting on top of head. Longer hair may take 1 to 2 hours.
    • lift a 1- to 2-inch wide strand of hair. Place comb as close to scalp as possible and comb with a firm, even motion away from scalp.
    • pin back each strand of hair after combing
    • clean comb often. Wipe nits away with tissue and discard in a plastic bag. Seal bag and discard to prevent lice from coming back.
    • after combing, thoroughly recheck for lice/nits. Repeat combing if necessary.
    • check daily for any lice/nits that you missed
    • a second treatment must be done in 7 to 10 days to kill any newly hatched lice
