Why Do My Eyelashes Fall Out Seasonally Common Triggers And Prevention Tips

It’s not uncommon to notice more eyelashes on your pillow or in the sink during certain times of the year. While losing a few lashes daily is normal—just like hair shedding from the scalp—a noticeable increase during seasonal transitions can be alarming. Seasonal eyelash loss isn’t always a sign of a serious condition, but it can point to environmental changes, hormonal shifts, or lifestyle habits that affect lash health. Understanding the underlying causes and how to respond effectively can make a significant difference in maintaining strong, full lashes throughout the year.

The Natural Eyelash Growth Cycle

Eyelashes follow a growth cycle similar to scalp hair, consisting of three phases: anagen (growth), catagen (transition), and telogen (resting and shedding). Each lash stays in the anagen phase for about 30 to 45 days, much shorter than scalp hair, which explains their limited length. After this, the lash enters the resting phase before naturally falling out to make room for a new one.

On average, people lose 1 to 5 eyelashes per day. However, during seasonal shifts—particularly in spring and fall—many report increased shedding. This phenomenon may be linked to broader biological rhythms influenced by light exposure, temperature, and humidity.

“Just like our skin and scalp, eyelashes respond to environmental stressors. Seasonal changes can disrupt the delicate balance of the follicle cycle.” — Dr. Lena Patel, Dermatologist & Cosmetic Specialist

Common Seasonal Triggers of Eyelash Loss

Several factors tied to seasonal fluctuations contribute to temporary increases in lash shedding. Identifying these can help you take preventive steps before damage becomes noticeable.

1. Allergies and Eye Rubbing

Spring and early fall are peak allergy seasons due to pollen, mold spores, and dust. These allergens trigger histamine release, causing itchy, watery eyes. Frequent rubbing—even gently—can pull out lashes prematurely and inflame the follicles, weakening them over time.

2. Dry Air and Low Humidity

Colder months bring dry indoor air from heating systems, while summer heat and air conditioning can also reduce moisture. Dry conditions dehydrate lashes, making them brittle and prone to breakage. The meibomian glands along the lash line may also produce less oil, leading to irritation and poor lash retention.

3. UV Exposure and Sun Damage

Increased sun exposure in summer can damage lash proteins and follicles. UV radiation contributes to oxidative stress, accelerating aging in hair structures—including lashes. Without protection, prolonged exposure may shorten the anagen phase and lead to thinning.

4. Hormonal Fluctuations

Seasonal changes can subtly influence hormone levels. For example, melatonin production varies with daylight hours, and cortisol (stress hormone) levels may rise during transitional periods. These shifts can indirectly affect hair cycles, including lashes.

5. Changes in Skincare and Makeup Routines

People often switch products with the seasons—using heavier creams in winter or waterproof mascara in summer. Harsh removers, especially those containing alcohol or acetone, strip natural oils and weaken lash shafts. Waterproof mascara, if not removed properly, increases mechanical stress when tugged off.

Tip: Use a gentle, oil-based eye makeup remover to dissolve products without tugging or irritation.

Do’s and Don’ts: Lash Care Across Seasons

Season	Do’s	Don’ts
Spring	Use antihistamine eye drops for allergies; clean lashes daily; apply a nourishing serum	Rub eyes; use expired mascara; skip removing makeup
Summer	Wear sunglasses; hydrate lashes with castor oil; remove waterproof makeup gently	Leave makeup on overnight; swim with mascara; overuse eyelash curlers
Fall	Switch to hydrating facial products; avoid heavy eye creams near lash line	Introduce too many new products at once; ignore early signs of irritation
Winter	Use a humidifier; apply vitamin E-infused serums; avoid hot showers near face	Use drying cleansers; rub eyes due to dryness; sleep in eye makeup

Prevention Tips for Year-Round Lash Health

Maintaining strong, resilient lashes requires consistent care tailored to seasonal demands. Here are practical strategies to minimize seasonal shedding and support regrowth.

Nourish from Within

Diet plays a crucial role in hair health. Lashes benefit from nutrients such as biotin, vitamin E, omega-3 fatty acids, and protein. Incorporate foods like eggs, salmon, nuts, spinach, and sweet potatoes into your meals to support keratin production and follicle strength.

Use Lash Serums Wisely

Pep-boosting serums containing peptides, hyaluronic acid, or prostaglandin analogs (like bimatoprost, available by prescription) can extend the anagen phase. Over-the-counter options with panthenol or niacinamide offer milder but effective support. Apply nightly to clean lash lines for best results.

Avoid Mechanical Stress

Everyday habits like sleeping on your stomach, using eyelash extensions frequently, or over-curling can cause traction alopecia—hair loss from repeated pulling. Limit extension use to special occasions and give your natural lashes recovery time between applications.

Keep Your Eyes Clean

Buildup of oil, makeup, and debris can clog follicles and promote infection. Gently cleanse your lash line with a mild foaming cleanser or diluted baby shampoo on a cotton pad. Do this every evening to prevent styes or blepharitis, both of which can lead to lash loss.

Protect Against Environmental Damage

Sunglasses aren’t just for UV protection—they shield lashes from wind, dust, and pollution. In winter, wear goggles when skiing or avoid sitting directly in heated air vents, which accelerate dryness.

Tip: Store lash serums in a cool, dark place to preserve active ingredients and avoid contamination.

Real-Life Example: Sarah’s Spring Shedding Struggle

Sarah, a 34-year-old teacher from Oregon, noticed her lashes thinning dramatically each April. She blamed her new waterproof mascara, then her lash lift treatments. After consulting a dermatologist, she learned she had seasonal allergic conjunctivitis. Her nightly habit of rubbing her eyes after school was pulling out lashes already in the telogen phase.

Her doctor recommended non-drowsy antihistamines, daily lid scrubs, and a switch to hypoallergenic makeup. Within six weeks, shedding slowed, and by summer, her lashes were fuller than before. “I didn’t realize how much I was damaging them just by trying to relieve the itch,” Sarah said. “Now I keep eye drops handy and use a silk pillowcase to reduce friction.”

Step-by-Step Guide: Building a Seasonal Lash Care Routine

1. Assess Your Current Routine (Monthly): Note any changes in shedding, product use, or eye comfort.
2. Cleanse Gently Every Night: Use a fragrance-free cleanser to wipe the lash line without tugging.
3. Apply Lash Serum (Evening): Dab a thin layer along the upper lash line on clean skin.
4. Switch Products with the Seasons: Opt for hydrating formulas in winter, lightweight ones in summer.
5. Protect During High-Risk Periods: Wear glasses during allergy season; use UV-protective sunglasses in summer.
6. Take a Break from Extensions/Mascara (Quarterly): Allow lashes 4–6 weeks to recover from styling stress.
7. Monitor Diet and Supplements: Ensure adequate intake of biotin, iron, and essential fats.

When to See a Doctor

While seasonal shedding is usually temporary, persistent or patchy lash loss could indicate an underlying issue. Conditions such as blepharitis, thyroid disorders, alopecia areata, or fungal infections require medical diagnosis and treatment. If you experience any of the following, consult a dermatologist or ophthalmologist:

• Lash loss accompanied by redness, swelling, or crusting
• Bare patches on the lash line
• Symmetrical thinning that doesn’t improve after 8–10 weeks
• Loss of eyebrows or other body hair alongside lashes

“If shedding lasts longer than two months or appears abnormal, don’t wait. Early intervention can prevent permanent follicle damage.” — Dr. Raj Mehta, Oculofacial Surgeon

Frequently Asked Questions

Is it normal for eyelashes to fall out more in spring and fall?

Yes, many people experience increased shedding during seasonal transitions due to allergies, humidity changes, and hormonal shifts. As long as regrowth occurs within a few weeks and there’s no inflammation, it’s typically harmless.

Can stress cause my eyelashes to fall out?

Yes. Physical or emotional stress can trigger telogen effluvium, a condition where more hairs than usual enter the resting phase and shed. This can affect scalp hair and lashes alike. Managing stress through sleep, exercise, and mindfulness may help reduce shedding.

Are eyelash serums safe for long-term use?

Most over-the-counter serums with conditioning ingredients (like peptides or plant extracts) are safe for ongoing use. However, those containing prostaglandin analogs may cause side effects like darkened eyelids or iris pigmentation with prolonged use. Always follow label instructions and consult a doctor if using prescription formulas.
