Head Lice are a pain in the neck and sometimes one lice treatment is just not enough, especially when they keep coming back. Most people forget that manually nitpicking while using a Nit Comb is one of the most reliable treatments for head lice. Choose a metal comb – they have finer, thinner teeth. Wash your hair, and cover it with conditioner to facilitate easy movement of the comb in a painless manner. Put a white towel around your shoulder, then comb from the top downward. The towel will catch all the bugs that fall and you can remove the nits manually.
