While hair is still damp, start at the top of the head and lift a 2cm section of hair. Ensure the teeth of the comb are as deep into the hair as they can go and touching the scalp. Comb with a firm even motion away from the scalp to the end of the hair. Wipe nits completely from the comb with a tissue. Continue process with each section of hair. NeutraLice Natural Spray and Advance Lotion contain a lice comb to help detect and remove eggs. Also available is the NeutraLice Nitcomb-M3, a metal comb developed by a pharmacist. It has three rows of teeth which are fine and extra fine, and increases the effectiveness you get with a single row comb.
