Lice vs Dandruff – What is Difference Between
Lice and dandruff can look similar, but they’re actually really different in many ways. Here are some important differences between lice and dandruff include:
- Location: Lice lay eggs called nits and dandruff causes flaky skin on the scalp. Both look similar but the close inspection reveals key differences. Nits stick to the base of the hair or on hair – not on the scalp, while dandruff is visible on the scalp. Since dandruff is just flaky or dry skin, it will be easy to remove as you brush your hair, but nits are actually a bit challenging to remove.
- Itching: Lice and dandruff both itch, dandruff tends to itch when the scalp is dry, and lice may feel a crawling sensation on your scalp.
- Contagion: Dandruff is not contagious; the dry skin flakes can get anyone but they do not spread person to person. The head lice, in other hand, can easily spread person to person either through direct head-to-head contact or by wearing a helmet or other headgear.
- Lymph nodes: Dandruff is not causing any infection, but lice can cause bacterial infections, especially when a person scratches their scalp too hard and causes bleeding. Some people with lice notice that the lymph nodes are behind their ears or on their neck.
- Color: Dandruff are white or perhaps a little yellowish, and lice are tiny, and you need magnifying glass to see them. If you have bugs or black or brown spots in the hair or on the scalp, then this usually means you have lice, not dandruff.
