The technique described by Dr. Pearlman describes three steps:

1. Apply the wet lotion throughout the scalp.
2. Comb out as much excess lotion as possible.
3. Use a blow dryer to dry your child's hair. This dries the lotion on the scalp, and coats any lice in a shrink-wrap-like layer. The dry lotion must remain on the hair and scalp for at least 8 hours. Usually parents leave it in place until the child’s usual bath or shower the next day.

I wonder if step 3 is actually the key. As we see in a more recent publication that describes the use of a hair dryer alone to rid the scalp of head lice.

This is now my preferred treatment for head lice. When done correctly, I have had no problems with recurrence. Since treatment is benign, it is easy to treat the entire family.

This is a gem!
