What is the Difference Between Lice and Dandruff?

Lice and dandruff may look similar, but they have key differences that can help you distinguish between the two. Here are the main differences:

1. Cause: Lice are small parasitic creatures that feed off human blood, and their saliva irritates the scalp, causing itchiness and sores. Dandruff, on the other hand, is caused by sensitivity to oleic acid, a by-product of the Malassezia globosa microbe, which we all have on our scalps.
2. Location: Lice lay eggs called nits on hair strands, while dandruff causes flaky skin on the scalp. Nits stick to the hair and are hard to remove, whereas dandruff flakes easily and falls off hair.
3. Contagion: Dandruff is not contagious, but lice spread easily from person to person. Lice are contagious parasites that exist in three forms: eggs (nits), nymphs (young adults), and adult lice.
4. Appearance: While both lice and dandruff can cause an itchy scalp, lice can cause severe itching and red, bloody spots on the scalp. Dandruff is generally associated with patches of red skin.
5. Treatment: Due to their different causes, lice and dandruff require different treatments. Lice are typically treated with over-the-counter or prescription medications, while dandruff can be managed with medicated shampoos and maintaining a healthy scalp environment.
