10 Symptoms of Head Lice

9. Visible Eggs

One of the easiest ways to tell if lice have infected you is to look out for lice eggs (nits). They appear whitish-gray and are often confused with dandruff. Regarding size, they are often compared to a grain of sand, which might make spotting them difficult. To determine if you have lice eggs, try brushing your hair. Nice eggs won't disappear if touched, unlike dandruff, which is easily combed away. What makes lice eggs difficult to remove is the fact that they are attacked at the base of the hair, giving them a protective barrier.
