Have you ever noticed an eyelash on your cheek or pillow and wondered, “How many eyelashes do you lose a day?” You’re not alone. Eyelashes, just like the hair on your head, follow a natural growth and shedding cycle. Losing a few each day is normal—but how much is too much, and what can you do to keep your lashes healthy?
In this blog, we’ll explain the eyelash growth cycle, how many lashes you naturally shed, what can cause extra eyelash loss, and tips to maintain strong, beautiful lashes.
The Eyelash Growth Cycle
Before we talk numbers, it’s important to understand the eyelash growth cycle. Your lashes don’t last forever. They go through three main phases:
-
Anagen Phase (Growth Stage):
This is when eyelashes actively grow. Each lash stays in this stage for about 30–45 days. -
Catagen Phase (Transition Stage):
Growth stops, and the follicle shrinks. This lasts 2–3 weeks. -
Telogen Phase (Shedding Stage):
The lash falls out naturally, making room for a new one. This stage lasts 4–9 weeks.
Because each lash is in a different phase, you don’t lose them all at once. That’s why your lash line usually looks even, even when some lashes fall out.
How Many Eyelashes Do You Have?
Most people don’t know the actual number of lashes they have. On average:
-
Upper eyelid: 90–160 lashes in 5–6 rows.
-
Lower eyelid: 70–80 lashes in 3–5 rows.
That means you have about 200–300 eyelashes per eye. With this many lashes, losing a few each day won’t make a noticeable difference.
How Many Eyelashes Do You Lose a Day?
Here’s the answer you’ve been waiting for: It’s normal to lose 1–5 eyelashes per day per eye.
This natural shedding happens because old lashes fall out and new ones grow in. Over a month, you might lose 30–150 lashes from each eye—but they are quickly replaced thanks to the lash growth cycle.
If you’re losing more than that, or if your lashes don’t seem to grow back, it could be a sign of an underlying issue.
Do Eyelashes Grow Back?
Yes—eyelashes grow back in most cases. After a lash falls out, a new one usually takes 6–8 weeks to grow in fully. The regrowth time depends on your age, health, and whether the lash follicle is damaged.
If the follicle is intact, your lashes will regrow. But if the follicle is damaged by pulling, burns, or certain medical conditions, regrowth may take longer—or might not happen at all.
Why Are My Eyelashes Falling Out? Common Causes
While normal eyelash shedding is healthy, sometimes you may notice more lashes falling out than usual. Here are some common reasons:
1. Normal Shedding
Part of the eyelash growth cycle—completely natural.
2. Eye Rubbing
Frequent rubbing, especially when tired or removing makeup, can pull out lashes.
3. Mascara and Extensions
-
Heavy or waterproof mascara can stress your lashes.
-
Eyelash curlers may break lashes if used too roughly.
-
Lash extensions add weight and adhesive, sometimes leading to more shedding.
4. Medical Conditions
Issues like blepharitis (eyelid inflammation), thyroid disorders, alopecia, or infections can lead to lash loss.
5. Lifestyle Factors
Stress, poor sleep, and lack of nutrients (like biotin, vitamin E, and omega-3s) can weaken lash follicles.
How to Keep Eyelashes Healthy
Want to minimize eyelash shedding and support natural lash growth? Try these simple tips:
-
Be gentle with makeup removal. Use a mild, oil-free cleanser instead of scrubbing.
-
Avoid rubbing your eyes. Pat gently when washing your face.
-
Limit lash extensions and heavy mascaras. Give your lashes breaks to recover.
-
Eat a balanced diet. Nutrients like biotin, zinc, and healthy fats encourage stronger lash growth.
-
Practice good eye hygiene. Wash your eyelids if you have buildup or irritation.
Some people also use eyelash serums designed to support growth, but results can vary.
When to See a Doctor
Shedding 1–5 lashes daily is normal, but you should see a doctor or dermatologist if:
-
You consistently lose more than 5 lashes per day.
-
You notice bald patches along your lash line.
-
Your eyelids are swollen, itchy, or painful.
-
Your lashes aren’t growing back after several months.
These symptoms may signal an infection, skin condition, or other medical issue that needs treatment.
Fun Facts About Eyelashes
-
Eyelashes last about 3–5 months before shedding.
-
Lashes grow faster in younger people and slow down with age.
-
Everyone’s lash pattern is unique—just like fingerprints.
-
Ancient Egyptians were among the first to darken their lashes using kohl.
Final Thoughts: How Many Eyelashes Do You Lose a Day?
On average, you lose 1–5 eyelashes per eye each day—and that’s completely normal. Your lashes follow a natural growth cycle, so while some fall out, new ones are always growing in.
If you notice more shedding than usual, or your lashes aren’t coming back, it might be time to check your beauty routine or see a doctor. With the right care—like being gentle with your lashes, eating a healthy diet, and limiting heavy makeup—you can keep your lashes strong, full, and healthy.
