Losing a few eyelashes here and there is normal — but what if you’re suddenly noticing gaps or excessive lash fallout? If you’ve typed “Why are my eyelashes falling out?” into Google, you’re not alone. Eyelash loss (known medically as madarosis) can be caused by everything from bad beauty habits to underlying health issues.
In this post, we’ll break down:
-
The most common causes of eyelash loss
-
When to see a doctor
-
The best ways to regrow healthy, full lashes
1. Eye Makeup Habits
Heavy mascara, waterproof formulas, or forgetting to remove your makeup at night can weaken lash hairs and clog follicles.
Fix:
Use a gentle, oil-based eye makeup remover and avoid sleeping with makeup on. Choose conditioning mascaras and take makeup breaks when you can.
2. Overusing Eyelash Curlers or Extensions
Mechanical curlers and lash extensions can pull at your natural lashes — especially during removal.
Fix:
Use curlers sparingly and avoid extensions by using an eyelash growth serum instead. Avoid pulling or rubbing your eyes.
3. Blepharitis or Eye Infections
Chronic eyelid inflammation (blepharitis), styes, or infections like pink eye can lead to temporary lash loss.
Fix:
Practice good eyelid hygiene: wash your eyelids gently with diluted baby shampoo or a commercial lid scrub. If you suspect an infection, see your eye doctor.
4. Alopecia or Thyroid Disorders
Autoimmune conditions like alopecia areata or hormonal imbalances (like hypothyroidism) can cause eyelashes to fall out.
Fix:
If lash loss is sudden or paired with fatigue, weight changes, or hair loss elsewhere, speak to your healthcare provider. A blood test may be needed.
5. Nutritional Deficiencies
Lack of iron, biotin, zinc, or protein can lead to weaker hair growth, including lashes.
Fix:
Eat a balanced diet rich in leafy greens, lean proteins, and healthy fats. Consider a biotin supplement (after consulting your doctor).
6. Stress and Hormonal Changes
Physical or emotional stress can disrupt the natural lash growth cycle.
Fix:
Manage stress through sleep, exercise, or mindfulness. Lash fallout often reverses once stress levels normalize.
7. Certain Medications or Treatments
Chemotherapy, retinoids, and some blood pressure medications can cause lash thinning or loss.
Fix:
If you're on medication, talk to your doctor about side effects. They may recommend lash-safe alternatives.
Can Eyelashes Grow Back?
Yes! Most of the time, eyelashes do grow back — but it depends on the cause. The lash growth cycle takes about 6–8 weeks, so be patient. Treat your lashes gently and avoid harsh products during recovery.

When to See a Doctor
If your eyelashes are falling out in large patches, if you notice bald spots on your scalp or brows, or if you have eye pain, itching, or vision issues — it’s time to see a dermatologist or eye doctor.
Final Thoughts:
Eyelash loss is common and often reversible. By adjusting your beauty habits, boosting your nutrition, and being gentle with your lashes, you can help them grow back longer and stronger.
