Detection and diagnosis
Head lice and nits are usually most prevalent around and behind the ears and near the neckline at the back of the head.
Diagnosis to confirm the louse infestation is by finding a live nymph or adult louse on the scalp or hair, although this may be difficult as adult and nymphal lice are very small, move quickly, and avoid light. Use a fine toothed louse comb to help with correctly diagnosing head lice.
Lice Eggs that are attached within 6mm of the base of hair shafts suggest the person may have an active infestation.
Symptoms and diagnosis
Because head lice and lice eggs are very small and hard to see, a louse infestation is often difficult to detect and diagnose. At the time of detection, an average infestation often includes only 10-15 hatched lice and 20-30 eggs.
Symptoms and signs of infestation
Tickling feeling, like something’s moving in the hair. Excessive itching, usually caused by an allergic reaction to the bites of the head louse. Irritability and difficulty sleeping; head lice are most active in the dark
