You booked a full set. They looked amazing. And then-one week later-they’re gone.
If your lash extensions are falling out faster than they should, something is interfering with retention. In a healthy cycle, extensions should shed gradually over 2–3 weeks, not all at once. When they drop early, there’s always a reason.
As someone who has seen this happen countless times in a professional setting, I can tell you this: it’s rarely “bad luck.” It’s usually one of the factors below.
Let’s break it down clearly so you know exactly what’s happening-and how to fix it.
First: What’s Normal Shedding?
Your natural lashes grow and shed in cycles. On average:
You naturally lose 2–5 lashes per day
A full set typically lasts 2–3 weeks before needing a fill
Some minor shedding in the first 3–5 days can happen
If you’re losing large clusters within a few days, that’s not normal retention.
Now let’s talk about why.
1. Toronto Weather (Yes, It Matters)
Humidity and temperature affect lash adhesive.
In Winter:
Toronto air is extremely dry. Indoor heating lowers humidity even more. Lash glue needs proper humidity to cure correctly. If it cures too slowly or too quickly, bonding weakens.
In Summer:
High humidity speeds up adhesive curing. If the lash tech doesn’t adjust adhesive type or application speed, bonds can become brittle.
What this means for you: Retention can suffer simply because environmental conditions weren’t managed properly during application.
Professional lash artists monitor humidity and temperature in the room. If this isn’t controlled, retention drops fast.
2. You Got Them Wet Too Soon
This is one of the most common issues.
For the first 24 hours, you should avoid:
Steam
Heavy sweating
Sauna
Hot yoga
Long hot showers
Toronto example: You leave your appointment and head straight to a workout class or take a long hot shower in a condo with high humidity. The adhesive hasn’t fully stabilized yet-extensions start sliding off.
3. Oil-Based Products Are Breaking Down the Glue
Oil dissolves lash adhesive over time.
Common hidden oil sources:
Micellar water (some contain oils)
Cream cleansers
Eye creams migrating into lashes
Makeup removers
Face oils
Even sunscreen can migrate upward in summer.
If extensions are falling out quickly and you’re using heavy skincare around the eyes, this is often the reason.
Solution: Switch to an oil-free cleanser specifically safe for extensions.
4. You’re Touching or Sleeping on Them
Be honest-are you:
Rubbing your eyes?
Sleeping face-down?
Picking at lashes?
Pulling out loose ones?
Mechanical stress breaks bonds.
Side sleepers often lose more lashes on one side. If one eye looks thinner than the other, this is usually why.
Fix:
Sleep on your back if possible
Use a silk pillowcase
Brush lashes gently daily
5. Your Natural Lash Cycle Is the Real Cause
Sometimes retention is fine-the problem is your natural lashes.
Stress, illness, seasonal shedding (common in fall), hormonal changes, and even starting or stopping certain medications can increase natural lash shedding.
If extensions are falling out attached to your natural lash, that’s normal shedding-not glue failure.
If extensions fall off alone (no natural lash attached), that’s a bonding issue.
6. Poor Application Technique
This is uncomfortable to say, but it’s real.
Retention suffers when:
Too little adhesive is used
Extensions are applied too far from the lash base
Isolation is poor
Lashes are applied to baby lashes that aren’t strong enough
Lashes are too heavy for your natural lash strength
Overly heavy volume fans are one of the biggest causes of early loss.
If retention has suddenly changed and nothing else is different, it may be internal.
How to Improve Lash Retention Immediately
Here’s a simple checklist:
✔ Keep lashes dry for 24 hours ✔ Avoid steam and heavy sweating right away ✔ Use only oil-free products ✔ Wash lashes gently every 1–2 days ✔ Brush daily with a clean spoolie ✔ Sleep on your back or use silk ✔ Book fills every 2–3 weeks ✔ Choose a reputable, experienced lash artist
Realistic Expectations
Good retention means:
Full, fluffy look for 2 weeks
Noticeable thinning around week 3
Time for a fill
If you expect them to look perfect for 4–5 weeks without maintenance, that’s unrealistic.
When to Talk to Your Lash Tech
If your extensions:
Fall out in large clusters within 3–5 days
Drop without natural lashes attached
Irritate or burn
Shed significantly more than usual
A professional should assess humidity, glue type, lash weight, and your aftercare routine.
Fast Lash Shedding is Almost Always Preventable.
It’s usually one of three things:
Environment
Aftercare
Application technique
If you live in Toronto, seasonal dryness and indoor heating alone can impact retention-but with the right technique and care, your lashes should last.
