How to Take Care of Eyelash Extensions: Expert Aftercare Guide 2026
Proper eyelash extension aftercare is the difference between lashes that last six weeks and lashes that fall out in ten days. If you’ve invested in professional eyelash extensions, knowing how to take care of eyelash extensions correctly determines whether you’ll love your results or regret your appointment. This guide covers everything from the critical first 48 hours to your daily maintenance routine, product recommendations available in Quebec, and climate-specific tips for Montreal’s humid summers and dry winters.
Whether you’re preparing for your first appointment or looking to improve your lash extension retention, you’ll learn exactly what products to use, which habits damage your lashes, and how to adjust your routine based on lifestyle factors like gym workouts and swimming.
Quick Answer
Keep lash extensions dry for 24-48 hours after application, clean them daily with oil-free cleanser, avoid oil-based products and rubbing your eyes, brush them gently with a spoolie, and book refills every 2-3 weeks to maintain fullness.
Why Proper Aftercare Is Critical for Your Lash Extensions
The adhesive bond between your natural lash and the extension takes 24-48 hours to cure completely. During this time, exposure to water, steam, or oil-based products can weaken the lash bond before it fully sets. After the initial curing period, your daily habits directly impact how long your extensions stay intact.
Most clients who experience poor retention are not dealing with low-quality work. They are unknowingly breaking down the adhesive with oil residue from skincare products, sleeping face-down, or skipping daily cleaning. Natural oils from your skin migrate to your lash line throughout the day, and without proper cleansing, this buildup weakens the bond and attracts bacteria.
At Labelle Eyes’ Westmount and Laval locations, the team provides detailed aftercare instructions specific to Quebec’s climate during every appointment. Clients who follow the recommended routine typically see retention rates above 80% at their three-week refill, while those who skip cleaning or use oil-based products often lose 40-50% of their extensions in the same timeframe.
Key Takeaways
- Wait 24-48 hours before exposing new lash extensions to water.
- Clean your lash extensions daily with oil-free cleanser to maximize retention.
- Avoid oil-based skincare products and makeup removers near your eyes.
- Book refill appointments every 2-3 weeks to maintain fullness and shape.
- Adjust your routine for Montreal’s humid summers and dry heated winters.
Timeline: Your First Week with Lash Extensions
Understanding what to expect during your first week and beyond helps you plan your aftercare routine and avoid common mistakes that compromise retention. This timeline shows the complete journey from application through your first refill appointment.
| Timeframe | What to Expect | What to Do | What to Avoid |
|---|---|---|---|
| Day 1 | Lashes feel slightly heavy as you adjust to the weight | Keep them completely dry, sleep on your back if possible | Water, steam, sweating, touching your lashes |
| Day 2 | Adhesive still curing, lashes settling into position | Continue avoiding water, resist urge to touch or check lashes | Showers on your face, gym workouts, swimming, all eye products |
| Day 3 | Adhesive fully cured, you can resume normal washing | Start daily cleaning routine with oil-free cleanser, brush with spoolie | Oil-based products, rubbing eyes, sleeping face-down |
| Days 4-7 | Lashes feel natural, may notice 1-2 extensions shed with natural lash cycle | Continue morning and evening brushing, clean daily after workouts | Waterproof mascara, oil-based makeup remover, pulling on lashes |
| Week 2 | Lashes remain full, natural shedding continues at 2-5 per day | Maintain daily cleaning and brushing routine consistently | Panicking over normal shedding, trying to remove loose extensions yourself |
| Week 3 | About 40-50% of extensions have shed naturally, time to book refill | Schedule refill appointment to maintain fullness and shape | Waiting beyond week 4, which requires a full new set instead of refill |
The first 48 hours require the strictest precautions. After day three, your focus shifts to daily maintenance habits that protect your investment for weeks to come.
The First 48 Hours: What You Must Avoid After Application
The first two days after your lash extension application require the strictest precautions. The adhesive remains in a semi-cured state during this period, vulnerable to moisture and heat.
Avoid all water contact for at least 24 hours, ideally 48 hours. This means no showers aimed at your face, no face washing, no steam rooms, and no swimming. If you absolutely must shower, angle your head away from the spray and use a shower visor to protect your lashes.
Skip the gym, hot yoga, and any activity that causes heavy sweating during the first 48 hours. Montreal’s humid summer weather makes this especially important. If you book your appointment in July or August, schedule it when you can stay in air conditioning for two days afterward.
Do not apply any products to your eye area. No mascara, no eyeliner, no eye cream, no face oil. Sleep on your back if possible. Side sleeping and stomach sleeping put pressure on your lashes and can cause them to bend or twist while the adhesive is still setting.
Expert Tip from Labelle Eyes
Clients who book evening appointments and go straight to bed after their session often see better retention than those who book midday and spend hours in summer humidity. The adhesive benefits from those still, climate-controlled overnight hours.
Your Daily Lash Extension Care Routine
Once the initial curing period passes, establishing a consistent daily routine becomes your most important retention tool. Lash extension maintenance requires just minutes per day but demands consistency.
Morning Grooming with a Spoolie Brush
Every morning after washing your face, gently brush your lash extensions with a clean spoolie brush. Start at the base of your lashes and brush upward and outward in the direction of the curl. This separates any lashes that crossed while you slept and restores their shape.
Nighttime Care and Sleeping Positions
Before bed, repeat the gentle brushing routine. If you wore eye makeup during the day, complete your cleansing routine first, then brush your lashes once they are dry. Sleep position affects retention more than most clients realize. Back sleeping is ideal, but if you are a dedicated side sleeper, try alternating sides to distribute pressure evenly. Silk or satin pillowcases create less friction than cotton.
Montreal winters present a specific nighttime challenge: bedroom air gets extremely dry when heating systems run constantly. A small bedroom humidifier set to 40-50% humidity helps maintain lash flexibility and comfort.
Expert Tip from Labelle Eyes
Clients who brush their lashes morning and night see 20-30% better retention at refill appointments than those who only brush when they remember. Consistency matters more than technique perfection.

How to Clean and Wash Your Lash Extensions (Step-by-Step)
Daily cleaning is non-negotiable for healthy lash extensions and good retention. Natural oil production, dead skin cells, dust, and makeup residue accumulate at your lash line every single day. Without removal, this buildup creates a barrier between the extension and your natural lash, breaking down the adhesive bond.
Clean your lashes every evening before bed, or twice daily if you wear heavy eye makeup or work out regularly. Fill a small bowl with lukewarm water and add a pump of oil-free lash cleanser or foaming face wash. Wet your lashes with clean water, then apply a small amount of cleanser to a clean spoolie brush or soft eyeshadow brush. Gently brush along the lash line in downward strokes, working the cleanser through the base of your extensions where oil and debris collect.
Focus on the lash line itself, not the length of the extensions. Use gentle pressure and short strokes. After 20-30 seconds per eye, rinse thoroughly with lukewarm water, using your cupped hand to splash water over your closed eyes until all cleanser residue is gone. Pat your lashes dry with a clean, lint-free towel or let them air dry. Never rub. Once dry, brush through with your clean spoolie to reshape and separate the extensions.

Products to Use and Avoid with Lash Extensions
Product selection makes or breaks your retention rate. Oil is the enemy of lash adhesive. Even tiny amounts from moisturizers, cleansers, or makeup removers migrate to your lash line and dissolve the adhesive bond over time.
Best Cleansers for Lash Extensions (Available in Quebec)
Look for cleansers specifically labeled as oil-free and safe for lash extensions. Foam cleansers work particularly well because they are easy to rinse and do not leave residue. Both Labelle Eyes locations sell professional-grade lash cleansers that meet these standards.
For local pharmacy options in Montreal and across Quebec, Neutrogena Oil-Free Eye Makeup Remover, Bioderma Sensibio H2O micellar water, La Roche-Posay Toleriane Dermo-Cleanser, and Cetaphil Gentle Foaming Cleanser are all available at Jean Coutu, Pharmaprix, and Uniprix locations. Always check ingredient lists and avoid any product listing mineral oil, coconut oil, argan oil, or any ingredient ending in “oil.”
Products That Break Down Lash Adhesive
Avoid all oil-based makeup removers, cleansing balms, and cleansing oils near your eyes. Most waterproof mascaras contain oils and waxes that do not rinse away easily. Face oils, serums containing oils, and oil-based moisturizers should stay away from your eye area. Apply these products carefully, stopping well below your orbital bone. Glycol-based products and products containing high concentrations of glycerin can also interfere with adhesive.
Understanding Normal Lash Shedding vs. Poor Retention
Your natural lashes follow a growth cycle: anagen (growth phase), catagen (transition phase), and telogen (resting phase before shedding). Each natural lash completes this cycle independently, which is why you shed 1-5 natural lashes per eye every single day. This is normal, healthy, and continuous throughout your life.
When an extension is attached to a natural lash that is nearing the end of its growth cycle, the extension falls out when that natural lash sheds. This is not poor retention. It is biology. At any given time, roughly 20% of your natural lashes are in the telogen phase, preparing to shed within the next few weeks.
Good retention means that extensions attached to lashes in the anagen or early catagen phase stay attached until those natural lashes complete their growth cycle. Poor retention means extensions fall off natural lashes that are still actively growing.
You should expect to lose 2-5 extensions per day due to natural shedding. If you are losing 10-15 extensions per day within the first two weeks, something is wrong. The most common causes: oil exposure, inadequate cleaning, or rubbing your eyes.
Check your pillowcase every morning. Seeing one or two extensions is normal. Seeing five or more consistently indicates a problem. Similarly, if you notice significant gaps in your lash line within ten days of a fresh full set, review your aftercare routine for mistakes.
Some clients naturally have faster lash cycles than others. If you have always noticed that you shed hair and lashes quickly, you may need refills every two weeks instead of three, even with perfect aftercare. This is not a problem with the application. It is your personal biology.
Common Mistakes That Damage Your Lash Extensions
Even clients who follow most aftercare rules often make subtle mistakes that compromise their results. These errors usually stem from habits so automatic you do not realize you are doing them.
Rubbing your eyes is the most common retention killer. Allergies, dry eyes, and fatigue all trigger the urge to rub. If you have seasonal allergies, take antihistamines before your symptoms get bad enough to make you rub. For dry eyes, use preservative-free artificial tears instead of rubbing for relief.
Pulling on your extensions, even gently, damages both the extensions and your natural lashes. Some clients develop a habit of tugging their lashes to check if they are secure. This creates a self-fulfilling problem: the pulling loosens the bonds, which makes you pull more to check, which loosens them further.
Skipping cleaning is nearly as damaging as using oil-based products. Clients often skip their cleaning routine when tired or when lashes still look clean. But oil buildup is invisible until it has already broken down your adhesive. Even on days when you do not wear makeup and stay home, your skin produces oil that needs removal.
Using regular mascara on extensions creates clumping, makes cleaning difficult, and can pull extensions out when you try to remove it. If you absolutely must add mascara, use only extension-safe formulas and apply them only to the tips of the extensions, never at the base. Better yet, skip mascara entirely and add volume with a heavier set at your next refill instead.
Sleeping face-down consistently crushes your lashes against your pillow every night. Over weeks, this causes extensions to twist, cross, and lose their curl. If you wake up with misshapen lashes that brushing does not fix, your sleep position is likely the culprit.
How Lifestyle Factors Affect Lash Retention
Your daily activities and hobbies directly impact how long your extensions last. Understanding these effects helps you make informed decisions about timing appointments and adjusting your routine.
Gym Workouts and Exercise
Regular gym workouts require a modified aftercare approach. Sweat contains salt and oil, both harmful to lash adhesive. If you work out daily, clean your lashes immediately after each session. Bring a small bottle of lash cleanser and a clean spoolie to the gym. A quick 60-second cleanse in the locker room makes a significant difference in retention. Hot yoga studios maintain 40°C temperatures with high humidity, which softens the adhesive temporarily. Regular hot yoga practitioners often experience slightly reduced retention and should book refills every two weeks instead of three.
Swimming in Quebec Pools and Lakes
Swimming is possible with lash extensions, but it requires precautions. Chlorinated pool water and salt water both affect the adhesive. If you swim regularly during Quebec’s short summer season, rinse immediately after swimming with fresh water and clean thoroughly with oil-free cleanser once you return home. Goggles create pressure on your lashes but protect them from direct water contact. Weekly swimmers should expect to book refills every 2-3 weeks rather than stretching to four weeks.
Skiing and Winter Sports
Winter sports popular in Quebec create unique challenges. Skiing and snowboarding at Mont-Tremblant, Mont-Sainte-Anne, or other Laurentian resorts expose your lashes to cold, windy conditions that cause eyes to water constantly. After a day on the slopes, clean your lashes thoroughly once you are in a warm environment. Regular skiers should expect slightly reduced retention during winter months and may need to book refills more frequently.
Montreal Climate Considerations
Montreal’s dramatic seasonal shifts require aftercare adjustments. Summer humidity above 60% can slightly weaken adhesive bonds over time, while winter indoor heating drops humidity below 30%, making both natural lashes and extensions brittle. During humid summer months, pay extra attention to keeping your lashes clean. Winter heating creates the opposite problem. When indoor air drops below 30% humidity, lashes become dry and prone to breakage. Combat this with a bedroom humidifier.
When and How Often to Book Refills
Refill timing depends on your natural lash cycle, lifestyle, and how full you want to keep your lashes. Most clients book refills every 2-3 weeks. Waiting longer than four weeks means you will need a new full set rather than a refill, because too few original extensions remain to build on.
Book your refill when you have lost about 40-50% of your extensions. For most people, this happens around the three-week mark. If you are diligent with aftercare and have a slower lash cycle, you might stretch to four weeks. If you work out heavily, swim regularly, or have a faster lash cycle, two-week intervals maintain better fullness.
During refill appointments, your technician removes any outgrown extensions, cleans your lashes thoroughly, and applies new extensions to fill the gaps. This process typically takes 45-75 minutes depending on how many lashes need replacement.
Classic lash extensions require refills every 2-3 weeks. Hybrid sets follow the same schedule. Volume lashes sometimes last slightly longer between refills because the multiple-fan technique provides more coverage.
At Labelle Eyes’ Westmount and Laval studios, the team tracks your retention patterns over multiple appointments and can help you identify your ideal refill schedule based on how your lashes respond.
Frequently Asked Questions
How often do I need to get my eyelash extensions filled?
Most clients need refills every 2-3 weeks to maintain fullness. Your natural lash cycle determines the exact timing. Book when you have lost about 40-50% of your extensions. Lifestyle factors like swimming, daily workouts, and oil-based skincare can shorten this timeline to two weeks, while clients with slower lash cycles sometimes extend to four weeks between appointments.
Can I get my eyelash extensions wet, and when is it safe?
Wait 24-48 hours after application before getting your extensions wet. During this time, the adhesive is still curing and remains vulnerable to moisture. After the initial curing period, you can shower, wash your face, and get your lashes wet normally. Avoid high-pressure water directly on your lashes and always clean them thoroughly with oil-free cleanser afterward.
Will cleaning my lashes make them fall out faster?
No. Proper cleaning with oil-free products actually improves retention. Natural oils from your skin, dead skin cells, and environmental debris accumulate at your lash line daily. Without removal, this buildup breaks down the adhesive bond. Daily gentle cleaning removes these retention-damaging elements. Clients who clean daily see 20-30% better retention than those who skip cleaning.
What happens if I accidentally get my lash extensions wet before 24 hours?
Brief moisture exposure within the first 24 hours usually does not ruin your entire set, but it can weaken some bonds and cause premature fallout over the next few days. If you accidentally get your lashes wet early, gently pat them dry with a lint-free towel and let them air dry completely. Monitor them over the next week for increased shedding.
Can I wear mascara on my eyelash extensions?
You can, but it is generally not recommended. If you do choose to use mascara, only use extension-safe formulas that are water-based and oil-free, and apply only to the tips of the extensions, never at the base. Avoid waterproof mascara completely, as the removal process requires oil-based removers that dissolve lash adhesive. If your extensions do not provide enough volume, consider upgrading to a fuller lash style at your next refill.
Your Next Steps for Beautiful, Long-Lasting Lashes
Taking care of your eyelash extensions correctly transforms them from a short-term beauty treatment into a sustainable part of your routine. The difference between lashes that last two weeks and lashes that last six weeks comes down to daily habits: cleaning with oil-free products, avoiding rubbing, adjusting for climate conditions, and booking refills on schedule.
