How many eyelashes do you lose a day?

how many eyelashes do you lose a day

Lash loss can be distressing, but a certain amount of it is actually pretty normal. So how many eyelashes do you lose in a day? If all is going well, the number is pretty small. In some cases, however, lash loss can indicate that you’re not gentle enough with your lashes or have an underlying health issue. This post explores everything you need to know about losing lashes.

Our lashes go through a growth and shedding cycle, so losing a few lashes a day is perfectly normal. If you notice a few lashes dropping to your cheeks over the course of a day or coming off on your cotton pad at the end of the night, there’s no need to worry. 

In fact, losing a lash is usually a signal that you have a hair follicle moving into its anagen phase, which is the phase when a new lash starts to grow. For that to happen, the old lash no longer growing must fall out first. 

However, if you’re losing a lot of lashes every day, you might be experiencing abnormal lash loss, which might require some action. This post explains what can cause lash loss and what you should do depending on the cause. 


According to the American Academy of Ophthalmology, losing between one and five lashes daily is normal. This number is likely approximate since the topic hasn’t been investigated closely in the academic literature. If you lose more than five lashes one day but only one or two lashes on a different day, there’s probably no cause for concern.


Depending on how many lashes you’re losing per day, any of the following could be the reason why: 

Your Natural Lash Cycle

The main reason lashes fall out is simply because they reach the end of their life cycle and must fall out so a new lash can take their place. This is a natural and necessary process that is nothing to be concerned about. 

Excessive Friction

Lashes can also fall out prematurely because of too much rubbing or friction. The sources of friction can be anything, from how often you rub your eyes to whether you sleep with your face buried in your pillow. 

Mascara (And How You Remove It) 

Mascara, especially waterproof mascara, is a major culprit for excessive lash loss. Research shows that wearing mascara frequently over the course of a few years corresponds with greater lash loss. Additionally, removing mascara incorrectly, like trying to take off waterproof mascara with water, can lead to even more significant lash loss. 

Treatments and Medications 

Some medical treatments can impact the body in ways that lead to lash loss, sometimes along with hair loss from other body parts. That includes chemotherapy treatments, certain anticoagulants, hormonal medications, and more. These treatments are often life-saving, so speak to your doctor about potential ways to mitigate your treatment-induced lash loss. 

Health Conditions

Many health conditions can lead to lash loss and are quite diverse. They include skin and eye diseases like blepharitis, psoriasis, dermatitis, lupus, hormonal conditions like hypothyroidism, and even certain types of cancer. Mental health conditions can also lead to trichotillomania, which leads to compulsive pulling on hair or lashes. 

It’s important to address the underlying cause of all of these health conditions. If you’re experiencing severe lash loss, hair loss, or skin irritation, speak to your doctor. 


There are a few situations when you should worry about unusual lash loss and consider speaking to your doctor: 

  • Your lash line is becoming visibly sparse or with noticeable bald patches due to lash loss. 
  • You’re also losing hair from other body parts, like the brows or head.
  • You’re experiencing skin or eye irritation that might be related to your lash loss. 
  • You’re dealing with other health symptoms, including fatigue or stress. 


You can do many little things to keep your lashes healthy and prevent lash loss. Here are our key tips: 

  • Avoid rubbing your eyes or tugging on your lashes if that’s ever been your habit. 
  • Wear mascara less often. 
  • Use a quality, oil-based eye makeup remover to remove your mascara and other eye cosmetics. Let it soak through your lashes completely to break down your makeup so you can remove it with less rubbing. 
  • Sleep on your back to avoid your lashes coming in contact with your pillowcase at night. 
  • For even more protection, wear a 3D sleep mask at night to create a barrier around your eyelashes. 
  • Use a nourishing lash serum to promote better lash growth. 
  • Make sure you’re eating a healthy and nutritionally-complete diet with many vegetables, protein sources, complex carbs, and healthy fats. 
  • Prioritize your mental health and find ways to limit sources of stress in your life. 
  • If necessary, speak to your doctor about your lash loss. 


Losing lashes isn’t always a matter of concern. Losing between one and five eyelashes a day is normal as part of your natural lash cycle. Losing more lashes than that on a consistent basis can be a signal that there's something wrong, though. To preserve your lashes, make sure to care for them gently, and speak to your doctor if you think you’re dealing with an underlying health problem.
