How do you know the difference between lice and dandruff? It’s a common question, especially when you notice an itchy scalp or flaky skin. While both conditions can cause discomfort and embarrassment, they are caused by different factors and require different treatments. Understanding the key differences can help you identify the problem and take appropriate action to alleviate your symptoms.
Lice are tiny, parasitic insects that infest the hair and scalp. They are usually found on the scalp, but can also be found in the eyebrows and eyelashes. Lice are spread through close contact with an infected person, such as sharing hats, combs, or brushes. The most common symptom of lice is intense itching, which is caused by the lice biting the scalp to feed on blood. Lice can be identified by their small, white eggs, called nits, which are glued to the hair shafts close to the scalp. These nits are difficult to remove and require special treatment to eliminate the infestation.
On the other hand, dandruff is a common scalp condition characterized by flaking and itching. It is caused by a fungus called Malassezia, which naturally resides on the scalp. When the fungus overgrows, it can cause inflammation, irritation, and flaking. Dandruff can be influenced by factors such as stress, hormonal changes, poor diet, and harsh hair care products. Unlike lice, dandruff does not have eggs or live insects attached to the hair shafts. Instead, the flaky skin is a result of dead skin cells that are shed from the scalp.

When in doubt, it’s always best to consult a healthcare professional or dermatologist for an accurate diagnosis and appropriate treatment. If you suspect you have lice, it’s important to treat all family members and close contacts to prevent reinfestation. For dandruff, try using an anti-dandruff shampoo and maintain a healthy scalp care routine.
