  According to the American Academy of Pediatrics guidelines, the gold standard for diagnosing head lice is to identify a live nymph or adult louse. […] The guidelines recommend examining wet hair lubricated with hair conditioner or another product. Your child’s health care provider will carefully comb your child’s hair with a fine-toothed comb (nit comb) from the scalp to the end of the hair. If no live louse is found, the provider will likely repeat the entire exam at a second appointment. […] Your health care provider will also look for nits in your child’s hair. To find nits, your child’s provider may use a specialized light called a Wood’s light, which causes nits to appear bluish. But the identification of nits does not necessarily confirm the diagnosis of live lice. […] A live nit needs to be near the scalp to survive. Nits found more than about 1/4 inch (6 millimeters) from the scalp are likely dead or empty. Suspect nits can be examined under a microscope to determine if they’re living.

[…] Head lice, the most common of the three types, is rarely a cause for concern and will be the primary type covered in this writing. […] Head lice are the most common type of lice and live out their entire lives in human hair. There are six to twelve million cases of head lice every year in the United States, with most of those cases in children between the ages of three and eleven.

A trained physician can examine pictures or videos and evaluate symptoms to determine if your suspicions are correct. They can recommend the best course of treatment based on your child’s age and the severity of infestation.
