Common Causes of Sudden Eyelash Itchiness
There are several reasons why your eyelash might itch suddenly. Some of the most common causes include:
- Allergic reactions to makeup, contact lenses, or eye drops
- Demodex mites, tiny parasites that live in the hair follicles
- Dry eyes or blepharitis, an inflammation of the eyelids
- Irritation from rubbing or touching the eyes
- Infections such as blepharitis or conjunctivitis
Allergic Reactions
Allergic reactions are a common cause of sudden eyelash itchiness. This could be due to an allergic reaction to a new makeup product, eye drops, or contact lenses. The immune system reacts to the perceived threat, releasing histamine and other chemicals that cause itching, redness, and swelling.

Demodex Mites
Demodex mites are tiny parasites that live in the hair follicles of humans. They can cause itchiness, redness, and inflammation in the eyelash area. These mites are usually harmless but can multiply rapidly, leading to uncomfortable symptoms.
Symptoms of Demodex mites include:
- Itching or tickling sensation in the eyelashes
