2. Polycystic Ovary Syndrome (PCOS) in Women
While ear hair is more common in men, women who develop coarse ear hair may have hormonal imbalances.
What it might mean:
-
PCOS causes excess androgens, leading to hirsutism (excess hair growth) in male-pattern areas
-
Other signs include irregular periods, acne, and scalp hair thinning
When to see a doctor: If you’re a woman with unexpected ear hair plus other hormonal symptoms.
3. Congenital Adrenal Hyperplasia (CAH)
This genetic condition affects adrenal gland function and can cause excess androgen production, leading to early or excessive hair growth.
4. Medication Side Effects
Certain medications can trigger hair growth, including:
-
Some blood pressure medications
-
Certain seizure drugs
-
Anabolic steroids
-
Cyclosporine (immunosuppressant)
