What are the Common Conditions That Cause Eyelash Loss?

Sometimes eyelash loss, or madarosis, is caused by more than the effects of aging, improper makeup or eye makeup use, or harsh products. There are many different physical conditions and bodily reactions that can trigger madarosis, which is also known as milphosis. It can then be important to rule out these causes with a thorough medical evaluation. They include:


An irritation of the lash line that cause itching and redness. The skin often becomes flaky, and the eyelashes may fall out.


Is an abnormal growth of lashes. It may cause lashes to be pushed out or irregular growth patterns along the eyelids.


Refers to ingrown eyelashes, which can cause irritation and infection leading to eyelash loss.

Staphylococcal infections may cause eyelash lightening, trichiasis, and loss. Other infections that may lead to eyelash loss include leprosy, chronic ulcerative blepharitis, tuberculosis, severe acute bacterial infections such as scarlet fever, viral infections such as herpes zoster, smallpox, measles, hepatitis, and Chlamydia trachomatis. Fungal infections may also cause madarosis.


The irritation and rubbing caused by allergic reactions may lead to eyelash loss. Tumors both benign, and malignant tumors in the eyelids can have eyelash loss as a symptom.

Thyroid disorders

Hypothyroidism may cause hair to become brittle, coarse, and thinner, which can lead to a diminished* appearance of eyelashes and possible loss.


Some drugs can cause eyelash loss as a side effect. Drugs are known to cause eyelash loss include the psoriasis medications Acitretin, Soriatane, and Neotigason. Other drugs that may cause eyelash loss include miotics, anticoagulants, anticholesterol drugs, antithyroid drugs, boric acid, bromocriptine, propranolol, valproic acid, cocaine use, and intoxication with arsenic, bismuth, thallium, gold, quinine, and vitamin A.
