Adults and children 2 years and over:

Inspect

• check each household member with a magnifying glass in bright light for lice/nits (eggs)
• 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 the 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
• if infestation continues, see a doctor for other treatments
