Why Are My Eyebrows Falling Out?
Eyebrows rarely come up in conversations about hair loss, even though thinning eyebrows is more common than it seems.
Published: 23 August 2026 · Updated: 23 August 2026
The most common causes
- Excessive mechanical removal — frequent plucking or tweezing.
- Hormonal disorders, including thyroid conditions.
- Certain skin conditions and nutrient deficiencies.
- The natural ageing process.
When it's a matter for a dermatologist
Sudden, asymmetric eyebrow loss, or loss accompanied by other skin changes — these are signals worth reporting to establish the cause, instead of waiting for it to "pass on its own".
What to discuss during a consultation
An article about “Why Are My Eyebrows Falling Out?” can help organise the subject, but the cause of a hair or scalp problem needs an individual assessment. Sudden or worsening hair loss, pain, itching or changes to the scalp should be discussed with a doctor or dermatologist.
Bring information about when the symptoms started, your health conditions, medicines and recent health changes. This helps clarify whether further tests are appropriate and what next steps may make sense.
