Lice
Lice are tiny, wingless parasitic insects that feed on the blood of humans. They are typically found on the scalp, but may also be found in the eyebrows and eyelashes. Lice are spread between people through direct contact with the hair, clothing, or other personal items of an infected person. Symptoms of lice include intense itching, red bumps on the scalp, and visible lice or eggs in the hair.
Dandruff
Dandruff is a scalp condition caused by an overgrowth of a yeast-like fungus called Malassezia. This fungus is naturally found on the scalp, but when it grows too much it can cause irritation and flaking. Symptoms of dandruff include white flakes of dead skin in the hair, itching, and redness.

The primary difference between lice and dandruff is the cause. Lice are caused by parasites that feed on the blood of humans, while dandruff is the result of an overgrowth of a yeast-like fungus. Additionally, lice can be spread between people, while dandruff cannot.
Treatment
