Why Are My Eyelashes Falling Out? 6 Everyday Causes

TL;DR: Losing 1–5 lashes a day is completely normal. When shedding spikes, everyday culprits like mascara habits, extensions, or inflammation are usually to blame. Here’s how to identify what’s going on — and how to give your lashes some love. The good news: that love is a ten-second daily habit, not a project.

You spotted a lash on your cheek and made a wish. Cute. But lately it feels like every time you take off your makeup there are more lashes on the cotton pad than on your actual lids. What gives?

Let’s break down the six most common reasons lashes shed — and separate the totally-normal from the worth-paying-attention-to.

1. The Normal Lash Cycle (Yes, This Is Supposed to Happen)

Each eyelash follows a three-phase growth cycle: anagen (active growth), catagen (transition), and telogen (resting/shedding). Because each lash is on its own independent schedule, you’ll naturally lose a few every single day. According to the Cleveland Clinic, losing 1 to 5 eyelashes per day is completely normal — and most of us barely notice it. The full cycle takes roughly 4 to 11 months from growth to shed, so patience is key after any noticeable loss.

2. Rubbing Your Eyes

It feels so satisfying in the moment, but rubbing your eyes is one of the fastest ways to mechanically dislodge lashes before they’re ready to fall. The friction also irritates the delicate eyelid skin and can introduce bacteria to the lash follicles. If you’re a habitual eye-rubber — especially during allergy season — this one’s worth breaking.

3. Eyelash Extensions and Traction Alopecia

Extensions can look incredible, but there’s a real trade-off. The AAO EyeWiki notes that eyelash extensions have been associated with traction alopecia — hair loss caused by the sustained weight and pull on natural lashes. The adhesives used can also trigger allergic blepharitis, with symptoms like redness, swelling, and irritation appearing hours or even days after application. If you’re a regular extension-wearer and noticing shedding between fills, your natural lashes may be under stress. For a deeper look, see our full guide: Are Eyelash Extensions Bad for Your Lashes?

4. Mascara and Curler Habits

Waterproof mascara requires more aggressive removal, and vigorous rubbing at the end of the day can pull lashes out. Using a mechanical curler on already-brittle lashes adds physical stress that compounds over time. Sleeping in mascara is another major offender — it dries out the lashes overnight, making them more prone to breakage come morning.

Simple swaps: use an oil-based or micellar cleanser, press don’t rub, and always remove makeup before bed.

5. Blepharitis and Other Eye Conditions

Blepharitis is inflammation of the eyelids — often caused by skin conditions like seborrheic dermatitis, rosacea, or a Demodex mite overgrowth. The Cleveland Clinic identifies blepharitis as a leading cause of lash loss because the inflammation can disrupt the follicles right at the lash line. If your lids are consistently crusty, itchy, or red, see an eye doctor — this isn’t a skincare fix, it’s a medical one. This article is not medical advice.

6. Aging, Nutrition, and Underlying Health

Just like scalp hair, lashes can thin with age as follicle activity naturally slows. Nutritional gaps — particularly in biotin, iron, or protein — can accelerate shedding. Autoimmune conditions like alopecia areata may also affect lashes and brows. If shedding is sudden, patchy, or accompanied by other symptoms, check in with your doctor before reaching for any topical product.

The 10-second daily habit that puts you back in control

Here’s the good news: while you sort out the underlying cause, you don’t have to just watch the cotton pad and hope. A little daily attention to the lashes you have is the one move that’s completely in your control — and doing something feels a whole lot better than doing nothing.

That’s exactly what our Let It Thrive Eyelash Serum is made for. It’s a lightweight, water-based formula built on pumpkin seed extract and rosemary — two of the most-studied botanicals in hair and scalp care — that conditions lashes along the lash line and supports the appearance of fuller, healthier-looking lashes, with no prostaglandins and no biotin. It’s a quick step to add wherever your routine already lives.

Why those ingredients? Pumpkin seed and rosemary are among the most-studied botanicals in hair and scalp care — honest caveat, because we don’t do hype: most of that research is on scalp hair, not lashes specifically, so it’s supportive, cosmetic lash care; it won’t replace addressing an underlying cause like blepharitis or a nutrient gap.

Once you’ve ruled out the medical stuff, give your lashes the daily habit that’s actually in your control. Shop the Let It Thrive Eyelash Serum. Explore more in our face collection.

FAQ

Is it normal to lose eyelashes every day?

Yes. Losing 1 to 5 lashes per day is within the normal range, per the Cleveland Clinic. Each lash is on its own growth cycle, so a few on your pillow or cotton pad is nothing to panic about.

Can stress cause eyelash loss?

Significant physical or emotional stress can push hair follicles — including lash follicles — into a resting/shedding phase earlier than usual. This is called telogen effluvium. If stress-related shedding is severe or prolonged, a doctor can help assess it.

Will my eyelashes grow back?

In most cases, yes — provided the follicle isn’t permanently damaged. The timeline depends on the underlying cause. Cosmetically, a gentle conditioning serum can help support lash appearance while you wait. For any medical concern, please consult an eye doctor or dermatologist.

Can eyelash extensions cause permanent loss?

Repeated traction stress over time can damage follicles. The AAO EyeWiki specifically flags traction alopecia as a known risk with extensions. Taking breaks between sets and using a lighter extension weight can help minimize stress on your natural lashes.
