Eyelashes are a group of hairs that grow on the edge of eyelids. They are designed to protect the eye from debris, dust, and objects that can cause injury or infection.
Like other body hair, natural lashes fall out and grow back following a 10-week eyelash growth cycle. It is common to lose one to five eyelashes a day.2
However, chronic eyelash loss (also called madarosis) can signify an underlying medical condition. Common health conditions that cause eyelashes to fall out include:
Certain medications, chronic stress, and nutritional deficiencies (iron, zinc, niacin) are less common causes of eyelash loss.
Eyelashes typically grow back, but it depends on the underlying cause of lash loss and if there is permanent hair follicle damage.
The natural eyelash life cycle takes 4 to 11 months and consists of three phases:
Treating the underlying medical condition or secondary cause of eyelash loss can help get the growth cycle back on track.
Eyelashes take about 4 to 10 weeks to regrow. However, they might take longer depending on the cause of lash loss. For example, pulled or burned lashes can take 6 weeks to a couple of months to grow back.4
For people with a health condition causing eyelashes to fall out, hair growth may not be stimulated until the medical condition is treated and managed. People with alopecia areata can be effectively treated with a topical bimatoprost-induced eyelash growth serum.5
Various eyelash growth serums on the market are proven to stimulate active growth.
The most common lash serums stem from topical bimatoprost 0.03%, approved by the FDA to increase lash length and thickness and make them darker. Bimatoprost is also used to treat glaucoma.5
Common growth serum products include:
Vitamins are essential for hair growth and healthy lashes. Multivitamin supplements can help you get daily doses of specific vitamins linked to hair growth, including:9
What you eat plays a significant role in eyelash growth. Nutritional deficiencies can lead to hair loss.10
Eating a diet rich in fruits, vegetables, and protein ensures you get the proper vitamins and minerals. To encourage eyelash growth, you should include the following in your diet:
Many mascaras and cosmetics also contain biotin, peptides, and vitamins that nourish lashes and promote hair growth.
Switching your eye makeup to include products that contain these ingredients can leave you with lush, beautiful lashes.
Tips for Preventing Eyelash Loss
Eyelashes are a big part of our appearance. Daily habits and behavior changes can help prevent unnecessary eyelash loss.
Try incorporating these tips into your daily routine:
Eyelashes follow a natural hair growth cycle; losing a couple of eyelashes a day is typical. However, certain medical conditions and medications can cause extensive eyelash loss.
The good news is that eyelashes typically grow back in 4 to 10 weeks with the help of growth serums and treating the underlying health condition. Eyelashes that were pulled out or burned may take longer to regrow.
