- Tickling feeling as if something is moving in your hair.Centers for Disease Control and Prevention: Lice: Head Lice: Factsheet
- Intense itchingMayoClinic.com: Head Lice: Symptoms
- Small red bumps on your scalp, neck and shoulders (caused by an allergic reaction to the saliva).MayoClinic.com: Head Lice: Symptoms

Lice are fast moving, small (about the size of a strawberry or sesame seed) and avoid light, so they can be tricky to find. Using a fine-toothed louse comb can be helpful.Centers for Disease Control and Prevention: Lice: Head Lice: Diagnosis Lice eggs (nits) may be visible on hair shafts, but can be mistaken for dandruff. Eggs, however, can not be easily brushed away.
