Why Do My Eyelashes Fall Out More In Winter Causes And Simple Solutions

It’s not your imagination—many people notice their eyelashes thinning or falling out more during the winter months. While some shedding is natural, excessive lash loss in cold weather can be alarming. The good news is that most causes are temporary and manageable with the right care. From dry indoor heating to harsh skincare routines, winter creates a perfect storm for weakened lashes. Understanding the underlying reasons and adopting targeted strategies can make a significant difference in maintaining full, healthy lashes throughout the season.

The Science Behind Eyelash Growth and Shedding

Eyelashes follow a natural growth cycle similar to scalp hair, consisting of three phases: anagen (growth), catagen (transition), and telogen (resting/shedding). On average, each lash grows for about 30 to 45 days before entering the resting phase and eventually falling out. A person typically loses 1 to 5 lashes per day—this is normal and part of the renewal process.

However, external stressors can disrupt this cycle, pushing more lashes into the telogen phase prematurely. This condition, known as telogen effluvium, can be triggered by seasonal changes, hormonal shifts, nutritional deficiencies, or environmental damage. In winter, multiple factors converge to increase lash shedding, making it seem more pronounced than at other times of the year.

“Seasonal changes, especially reduced humidity and increased exposure to indoor heating, create a dehydrating environment that directly impacts the health of delicate facial hair like eyelashes.” — Dr. Lena Patel, Dermatologist & Hair Specialist

Top 5 Causes of Increased Eyelash Loss in Winter

1. Low Humidity and Dry Air

Winter air, both outdoors and indoors, tends to be extremely dry. Central heating systems reduce indoor humidity to as low as 10–20%, far below the ideal 40–60%. This dryness strips moisture from skin and hair follicles, including those on your eyelids. Dehydrated follicles become brittle, weakening the lash shaft and increasing breakage and fallout.

2. Overuse of Harsh Makeup and Removal Products

Colder months often mean heavier makeup use—thicker mascaras, waterproof formulas, and false lashes. While these enhance appearance, they can stress natural lashes. Waterproof mascara, in particular, contains polymers that bind tightly to lashes and require aggressive rubbing or oil-based removers to remove. This friction weakens the lash base over time.

Tip: Always use a gentle, non-irritating eye makeup remover. Micellar water or dual-phase removers designed for sensitive eyes minimize tugging.

3. Frequent Rubbing Due to Dry or Irritated Eyes

Dry eyes are common in winter due to low humidity and prolonged screen use. When eyes feel gritty or itchy, people instinctively rub them—often without realizing how much pressure they’re applying to the lash line. Chronic rubbing can dislodge lashes prematurely and even damage follicles, leading to longer-term thinning.

4. Nutritional Deficiencies That Worsen in Winter

During colder months, dietary variety may decrease, and vitamin D synthesis drops due to limited sun exposure. Deficiencies in biotin, iron, vitamin E, and omega-3 fatty acids—all essential for hair strength—are linked to increased hair and lash shedding. These deficiencies may go unnoticed until symptoms like brittle lashes appear.

5. Skincare Ingredients That Irritate the Eye Area

Night creams, anti-aging serums, and acne treatments containing retinoids, alpha hydroxy acids (AHAs), or fragrances can migrate toward the eyes while sleeping. These ingredients may irritate the delicate skin along the lash line, causing inflammation that disrupts follicle function and accelerates shedding.

Effective Solutions to Prevent Winter Lash Loss

Combatting winter-related lash loss requires a multi-pronged approach focused on hydration, gentle care, and targeted nourishment. Implementing a few key habits can significantly reduce shedding and support regrowth.

Hydrate Your Environment

Since indoor dryness is a primary culprit, restoring moisture to your surroundings is critical. Using a humidifier in your bedroom overnight helps maintain optimal humidity levels, preventing your lashes (and skin) from drying out. Aim for 40–50% humidity, which supports healthy hair follicles without encouraging mold growth.

Switch to Lash-Safe Makeup Habits

Opt for lightweight, non-waterproof mascaras during winter. They’re easier to remove and less likely to cause buildup or brittleness. Avoid false lashes and heavy extensions if you're already noticing thinning—they add weight and stress to natural lashes. When removing makeup, use a cotton pad soaked in remover and hold it over closed eyes for 10–15 seconds to dissolve product before gently wiping downward.

Nourish Lash Follicles with Serums

Lash growth serums containing peptides, hyaluronic acid, or panthenol can strengthen follicles and improve retention. Look for ophthalmologist-tested formulas free from parabens and prostaglandins (which can cause side effects like darkening of the eyelid). Apply nightly to clean lash lines using the provided applicator, just as you would eyeliner.

Protect Lashes During Sleep

Sleeping face-down or on rough pillowcases increases friction. Switch to a satin or silk pillowcase to reduce drag on lashes and hair. Additionally, avoid sleeping with eye masks that press directly against lashes unless they’re made from soft, non-abrasive fabric.

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

1. Evening Cleanse: Remove eye makeup gently using a hydrating micellar water or oil-free dual-phase remover. Never tug or rub.
2. Treat: Apply a nourishing lash serum to the base of upper lashes using a sterile brush. Let dry completely before applying any night cream.
3. Moisturize Skin (Carefully): Apply facial moisturizer, avoiding direct contact with the lash line to prevent ingredient migration.
4. Humidify: Run a bedroom humidifier from evening until morning to maintain moisture in the air.
5. Morning Refresh: Rinse eyes with cool water and pat dry. Avoid touching or rubbing unless necessary.
6. Daytime Protection: If wearing mascara, choose a lengthening formula over volumizing ones, which tend to be heavier and more damaging.

Tip: Wash makeup brushes weekly to prevent bacterial buildup, which can lead to follicle infections and lash loss.

Mini Case Study: Sarah’s Winter Lash Recovery

Sarah, a 32-year-old teacher from Chicago, noticed her lashes were noticeably thinner by mid-January. She was using waterproof mascara daily and removing it with coconut oil and vigorous rubbing. After two months of persistent shedding, she consulted a dermatologist who identified dry environment and mechanical trauma as the main culprits.

Following a tailored plan—switching to a non-waterproof mascara, using a peptide-based lash serum, running a humidifier, and eliminating eye rubbing—Sarah saw improvement within six weeks. By March, her lashes had regained density and appeared healthier. Her experience highlights how simple behavioral changes can reverse seasonal lash loss.

Frequently Asked Questions

Is it normal to lose more eyelashes in winter?

Yes, mild increases in shedding can be normal due to dry air, indoor heating, and lifestyle changes. However, sudden or severe loss should be evaluated by a healthcare provider to rule out underlying conditions like blepharitis or thyroid disorders.

Can I use castor oil on my eyelashes?

Many people report benefits from castor oil due to its ricinoleic acid content, which may improve circulation to follicles. However, scientific evidence is limited. If you choose to use it, apply a tiny amount with a clean spoolie brush and avoid getting it into your eyes. Discontinue if irritation occurs.

How long does it take for eyelashes to grow back?

If the follicle is undamaged, lashes typically regrow within 6 to 8 weeks. Full restoration of length and thickness may take up to 12 weeks. Consistent care during regrowth improves outcomes.
