Signs and symptoms of lice include:
Intense itching.
Tickling feeling from movement of hair.
Lice on your scalp, body, clothing, or pubic or other body hair. Adult lice may be about the size of a sesame seed or slightly larger.
Lice eggs (nits) on hair shafts. Nits resemble tiny pussy willow buds. Nits can be mistaken for dandruff, but unlike dandruff, they can't be easily brushed out of hair.
Small, red bumps on the scalp, neck and shoulders.
