Can Lice Cause Hair Loss?


Yes, lice infestations can potentially lead to hair loss, but it is not the lice themselves that directly cause the hair loss. Instead, it is the scratching and irritation associated with a lice infestation that can result in hair loss.

When lice infest the scalp, they bite and feed on small amounts of blood from the scalp. This can cause intense itching and irritation. When a person repeatedly scratches their scalp to relieve the itching, it can lead to hair breakage and even hair loss over time. Additionally, the physical act of scratching can damage the hair shafts and weaken them, making them more prone to breakage.

It’s important to treat a lice infestation promptly to prevent further irritation, scratching, and potential hair loss. Over-the-counter and prescription treatments are available to eliminate lice, and it’s also essential to thoroughly comb and remove nits (lice eggs) from the hair to prevent reinfestation. If you or someone you know has a lice infestation and is experiencing hair loss, it’s a good idea to consult a healthcare professional or a dermatologist for guidance on how to address the issue and minimize hair damage.
