Comb strand by strand, starting closest to the scalp. Carefully set aside each strand free of nits and dead lice. Clean the comb between each strand with a cotton ball to prevent re-infestation. 5- Wash the hair: without rinsing out the lice treatment, apply shampoo for oily hair, distributing it throughout the hair. Use water to lather. Wash and rinse the hair thoroughly. Clean the comb with water and mild soap. Wipe it with a dry towel. Do not put in the dishwasher.
