It's normal to occasionally find a stray eyelash, but if you're noticing more frequent lash loss and your lashes becoming thinner, it can be concerning. In some cases, this may require a closer examination. Continue reading to discover the possible causes of eyelash loss and when to consult a doctor for a thorough assessment.
Common Causes of Eyelash Loss
According to cosmetic dermatologist Paul Jarrod Frank, MD, "Eyelash loss can occur for a variety of reasons. It may be due to using inappropriate products, experiencing high levels of stress, or improperly removing false eyelashes, but it could also indicate a more serious health condition."
As with any bodily change, the key to resolving the issue lies in identifying the underlying cause. Rather than jumping to conclusions and self-diagnosing with a severe illness, there are more likely reasons to consider first. Dermatologists suggest these are the most common causes if you're experiencing noticeable hair loss.
Natural Eyelash Loss as Part of the Hair Growth Cycle
Much like the hair on your scalp, eyelashes naturally shed and regenerate in a cycle that lasts between six and ten weeks. Losing between one and five lashes per day is entirely normal. Thinning lashes are also a natural aspect of aging, so if your lashes appear shorter or less full than before, there’s no need to worry. Shedding and thinning are typically part of the natural process and not a cause for concern.
Excessive Rubbing and Friction
Keeping the eye area clean from debris is important, particularly when removing makeup before bed, but experts recommend exercising caution when cleaning such a sensitive area. "It’s crucial to avoid any trauma to your lashes, including excessive rubbing, tugging, or applying too much force, especially near the eyelid," says Jenny Liu, MD, board-certified dermatologist.
A common source of friction affecting your lashes is your sleep mask. Celebrity lash expert Clementina Richardson, founder of Envious Lashes, notes that sleep masks can cause eyelash extensions to bend and lose their shape from pressure while you sleep. To avoid this, choose sleep masks that are adjustable or designed specifically for lash extension wearers.
Bacterial Infections from Expired Products
Neglecting the
expiration dates on your makeup might be the reason behind your lash loss. Frank highlights the importance of checking expiration dates, particularly on eye products, as expired makeup can lead to bacterial infections. "Mascara, for example, should be replaced every three months, as it is susceptible to staph buildup. A bacterial infection from expired products can cause inflammation, ultimately resulting in lash loss."
Allergic Reactions
While you're at it, it’s a good idea to review the ingredient list on your products. "Allergic reactions to cosmetics, eye makeup, skincare, and even nail polishes are frequent causes of eyelid dermatitis and, in severe cases, eyelash loss," warns Liu. If you think your eyelash loss is due to a reaction from cosmetics or eye cream, discontinue use of these products and get an allergy test to determine the specific allergens.
False Lashes
False lashes are another common culprit that can cause lash loss. "When it comes to extensions, many people develop an allergic reaction to the glue, leading to inflammation which may cause lashes to fall out. In the case of false lashes, the glue can bind to natural lashes, and if removed improperly, it can pull out the natural lashes," explains Frank. He recommends using a specific adhesive remover or an oil-based cleanser for gentler removal.
When to Consult a Specialist for Lash Loss Issues
If you've ruled out other causes and lash loss continues, it might be time to consult a doctor to investigate underlying conditions. If you notice eyelashes falling out on both eyelids, it could be indicative of a more systemic issue," says Frank. If you're also experiencing hair loss on your eyebrows or scalp, or skin issues such as redness, itching, or scaling, this may be a sign of a health concern. Here are some conditions a doctor can evaluate for eyelash loss.
Thyroid Disorders
Frank explains that the thyroid gland regulates the body’s hormones, and any imbalance due to an overactive (hyper) or underactive (hypo) thyroid can lead to eyelash loss. "Other symptoms might include weight fluctuations, temperature sensitivity, increased anxiety, and constipation, all of which are generally addressed through an endocrinologist's evaluation and appropriate medication," he adds.
Blepharitis
"Blepharitis is a condition marked by blocked glands that lead to inflammation, causing eyelashes to fall out. The bacteria that naturally live along the lash line often trigger this condition," explains Audrey Kunin, MD, a board-certified dermatologist. "The eyelids may appear crusty and swollen, red, and watery, with a gritty feeling. For treatment, Avenova Lid & Lash Spray, which contains hypochlorous acid, is gentle on the eyes while effectively targeting the source of blepharitis by eliminating the bacteria responsible for the inflammation."
Trichotillomania
"Trichotillomania is a condition in which individuals pull out their eyelashes due to emotional stress, and it may also have a genetic component," says Frank. Often referred to as a hair-pulling disorder, studies show that approximately one in 50 people will experience trichotillomania in their lifetime. This condition typically begins in late childhood or early adolescence and is commonly treated through therapy and/or medication. It’s recommended to see a therapist who can offer treatment for impulse control disorders like this one.
Certain Cancers
Although uncommon, Kunin points out that localized skin cancers on the eyelids can lead to lash loss because cancer impacts the hair follicles. "Any persistent sores, scabs, or crusting should be warning signs to get your eyes checked." If you notice any of these symptoms, it’s important to consult with your doctor as soon as possible.
Frequently Asked Questions
What purpose do eyelashes serve?
Eyelashes primarily act to sweep away dust, pollen, debris, and other airborne bacteria from the eyes, serving as a protective barrier for sensitive eye tissue. They also help prevent moisture, like sweat, from reaching the eyes.
How can I encourage my lashes to regrow?
Lash growth serums can be used to address hair loss or eyelash hypotrichosis (when there are very few eyelashes). The only FDA-approved treatment for lash regrowth is Latisse. A balanced diet with biotin may also help, as lash serums might not always be effective and could cause irritation. Consider giving your lashes a break from mascara to allow them to recover.
