Lice and Dandruff share some similarities, but are two totally different conditions of the scalp. Which means they also have two completely different causes and treatments.
The two symptoms common to both head lice and dandruff are itching and white particles in your hair and scalp.
Symptoms unique to head lice are: movement of white particles on your scalp, also known as head lice. Also, having nits, eggs stuck to your hair and scalp.
Dandruff symptoms: white specks in your hair that easily fall out, and a white or yellow scalp that is scaly.
If you have symptoms that are similar to lice or dandruff, it is important to get it checked by a lice treatment professional. It is better to be safe than sorry!
