10 Symptoms of Head Lice

5. Irritation of the Scalp

Lice are hungry creatures, and their hunger's hard to satisfy. That's why they're almost on a permanent mission to grow and consume. Sweat, blood and dead skin cells are just some of the many delicacies that head lice like to munch on. As a result, irritation to the scalp and surrounding area is a common symptom of head lice. To make matters worse, scratching on the surface of the scalp will only make the area more inflamed and irritated. You may experience bleeding, and even in some cases, an infection may develop. Irritation may also occur on the ear.
