Treatments Your Provider May Prescribe
In order to make a diagnosis of head lice, the doctor must see a louse or a nit on the scalp. Occasionally, a Wood's lamp is used to look for lice and nits. In this procedure, the doctor shines a black light at the scalp, and the insects and eggs appear as yellow-green fluorescent spots under this light.

Once the diagnosis of head lice has been confirmed, the doctor may recommend one or more of the following treatments in addition to the self-care measures outlined above:
  • Permethrin lotion or shampoo
  • Malathion lotion
  • Lindane lotion, cream, or shampoo (not used as much anymore due to potential toxicity)
  • Ivermectin pills
