How many eyelashes are usually lost in a day?

Eyelashes are essential in protecting our eyes from dust, debris, and other harmful particles. However, like all hair on our bodies, eyelashes naturally fall out and are replaced with new growth. A look at the rate at which eyelashes fall out, and the factors that may play a part in this are discussed in this article.

How Many Eyelashes are Usually Lost in a Day?

On average, losing one to five eyelashes per day is customary. This may seem like a lot, but it is important to note that we have between 90 to 150 lashes on our upper eyelids and 70 to 80 on our lower eyelids. Losing a few lashes daily is a natural part of the growth cycle and should not cause concern.

Factors that Affect Eyelash Loss

Eyelash loss is a common occurrence that affects many people. While losing a few eyelashes daily is normal, excessive eyelash loss can be concerning. Several factors can contribute to the loss of eyelashes. Here are some of the most common factors that affect eyelash loss:


As mentioned earlier, age is a significant factor that affects eyelash loss. Our hair follicles become less active as we age, leading to thinning and hair loss. The same is valid for eyelashes. While it is normal to lose a few eyelashes every day, the rate of eyelash loss tends to increase with age. It is because the hair growth cycle slows down, resulting in fewer new lashes replacing the old ones that have fallen out. Additionally, the quality of lashes also tends to decline with age, becoming thinner, shorter, and less pigmented.

While aging is a natural process and cannot be stopped, several steps can be taken to slow down the rate of eyelash loss. Using a nourishing lash serum or applying castor oil to the lashes can help keep them healthy and promote growth. Maintaining the health of lashes can also be achieved by eating a healthy diet rich in vitamins and minerals. As a temporary solution to severe age-related eyelash loss, eyelash extensions or false lashes can be used. It is essential to consult a professional to ensure their safety and proper application.

Eye Irritation

Eye irritation is another factor that can lead to increased eyelash loss. When the eyes are irritated, it is common to rub or scratch them, which can result in the loss of eyelashes. Using specific eye makeup or removers can also cause irritation and lead to eyelash loss.

To minimize eye irritation, it is essential to use gentle and non-irritating products around the eye area. Avoid rubbing or scratching the eyes and lashes as much as possible, and be sure to remove eye makeup thoroughly at the end of the day using a gentle, oil-free remover. Keeping the eye area clean and free of bacteria is also essential, which can cause infections and further irritation.

Hormonal Changes

Hormonal changes can also be a factor in increased eyelash loss. The hormonal fluctuations that occur during pregnancy, menopause, and other times of hormonal imbalance can cause changes in hair growth patterns, including eyelashes. In some cases, hormonal imbalances can lead to hypotrichosis, which causes a significant loss of eyelashes and hair.

If hormonal changes are causing eyelash loss, it is essential to address the underlying hormonal imbalance through medical treatment. A doctor may prescribe medications or hormone replacement therapy to balance hormone levels and reduce eyelash loss. In some cases, using lash growth serums or products containing prostaglandin analogs can also effectively promote eyelash growth. However, discussing such treatments with a healthcare professional before use is essential.


Certain medications can also lead to increased eyelash loss as a side effect. Chemotherapy drugs, for example, can cause hair loss all over the body, including the eyelashes. Eyelash loss can also be caused by other medications, such as those used to treat glaucoma. A healthcare professional should be consulted if medication is causing eyelash loss.

Sometimes, switching medications that do not have the same side effects may be an option. In other cases, the medication may be necessary to treat a more severe condition, and eyelash loss may be a temporary side effect that will resolve once the medication is discontinued. A healthcare professional can provide guidance on the best course of action in such cases.

Eye Makeup

Wearing eye makeup can also be a factor in increased eyelash loss. Mascara, eyeliner, and other eye makeup products can cause eyelashes to become brittle and more likely to break. Additionally, not removing eye makeup properly can accumulate makeup residue on the eyelashes, which can cause irritation and damage to the hair follicles.

Choosing high-quality products that are gentle on the eyes and eyelashes is essential to minimize eyelash loss from makeup use. Removing eye makeup thoroughly every night with a gentle makeup remover is also important. Avoiding the use of eyelash curlers can also help to prevent damage to the eyelashes. If eyelash loss has already occurred, using a lash growth serum or consulting a healthcare professional may help to promote regrowth.


Stress is another factor that can contribute to increased eyelash loss. When the body is under stress, it produces hormones such as cortisol, which can impact hair growth cycles. High-stress levels can cause the hair follicles to enter the telogen (resting) phase prematurely, leading to increased hair shedding, including eyelashes.

To manage stress and prevent increased eyelash loss, it is important to prioritize self-care and stress-reducing activities such as exercise, meditation, or spending time with loved ones. Stress levels can also be managed by seeking professional help from a therapist or counselor. As well as ensuring a healthy diet, eyelashes can get the nutrients they need to grow strong and healthy.

Nutritional Deficiencies

Nutritional deficiencies can also cause eyelash loss. Biotin, vitamin E, and iron deficiencies have been linked to hair loss and brittle hair. B vitamin biotin is essential for healthy hair growth. Vitamin E acts as an antioxidant and promotes hair health. In order for hair follicles to receive oxygen, iron is necessary for the production of hemoglobin.

To prevent nutritional deficiencies that can contribute to eyelash loss, eating a well-balanced diet that includes a variety of nutrient-rich foods such as leafy greens, whole grains, nuts, and lean protein sources is essential. A healthcare professional may also recommend supplementation with vitamins and minerals if necessary. Before starting a new supplement regimen, seeking advice from a healthcare provider is important.

When to Seek Medical Attention

While losing a few eyelashes daily is normal, excessive eyelash loss may indicate an underlying medical condition. If you notice a sudden increase in eyelash loss, it is best to consult a healthcare provider or dermatologist. They can help determine if the eyelash loss is due to a medical issue or a medication side effect.

Final Thoughts

In conclusion, losing a few eyelashes daily is normal and should not cause concern. Factors such as age, eye irritation, hormonal changes, and medications can affect the amount of eyelash loss one experiences. However, if you notice a sudden increase in eyelash loss, it is best to seek medical attention to determine the underlying cause.
