Why Are My Lash Extensions Falling Out So Fast?

why my lash extensions fall fast

A Straightforward Guide for Toronto Clients

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.

A proper lash application should:

  • Match extension weight to natural lash strength
  • Maintain correct distance from lash line
  • Use proper adhesive amount
  • Ensure clean, oil-free lashes before starting
mastering lash retention

7. You Didn’t Clean Them (Yes, That’s a Problem)

Many people think washing lashes makes them fall out.

Actually, not washing them causes buildup. Oil, makeup residue, and debris weaken the bond and cause premature shedding.

Clean your lashes gently every 1–2 days using:

  • Oil-free lash cleanser
  • Soft brush
  • Pat dry (don’t rub)

Especially important in Toronto winters when indoor air increases eye dryness and rubbing.

8. You Waited Too Long for a Fill

If you wait 4 weeks between fills, you’ll look like they “all fell out.”

Reality:
You shed about 30–40% of lashes every 2–3 weeks naturally.

Fills are needed every:

  • 2–3 weeks for classic
  • 2–2.5 weeks for volume

9. Health or Hormonal Factors

Some conditions affect retention:

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:

  1. Environment
  2. Aftercare
  3. 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.
