“Why Won’t These Lashes Stay On?” — What to Know When Extensions Just Won’t Stick

Let's face it, there aren't many things more annoying than spending time applying gorgeous lash extensions only to have them fall out much too quickly. This situation may be perplexing and discouraging, whether you're a client wondering why your new set didn't endure or a lash artist doubting your expertise.

You're not alone if you've ever cried out in silence, thinking, "Why aren't these lashes sticking?" The good news? Nothing is wrong with you. However, certain things are worth knowing.

Let's dissect it—not with blame, but with love.

1. It Might Not Be You — It Might Be the Environment

Lash glue is surprisingly particular. Temperature and humidity have an impact on how quickly (or slowly) it heals. The lash glue won't adhere correctly in an environment that is either too dry or too humid. If you try to bake a cake in an oven that is either too hot or too cold, the cake won't rise as much.

What helps:
  • 45–60% humidity is ideal.
  • Temperature range: 68–75°F (20–24°C)
  • A trustworthy hygrometer to keep an eye on conditions 
Sensitive lash glue


2. Oils Are Sneaky Little Saboteurs

Lash bonding may be hampered by greasy eyes, cosmetics residue, or skincare products. You might be surprised to learn how quickly glue can be broken down by even natural skin oils. For this reason, a very thorough cleaning is essential.

Before every set:
  • Make use of a lash cleanser without oil.
  • Steer clear of using thick creams around the eyes.
  • Use a lint-free applicator rather than merely water to clean.
Bonus tip: After your lashes are set, advise your customers not to use mascara or greasy makeup removers.

3. Poor Isolation = Poor Retention

For a moment, let's go technical. The link won't last if you're not adequately isolating, which means one natural lash will adhere to its neighbour. It may result in pain, injury, or early fallout.

It's more about accuracy than speed.
Go slowly. Make use of good tweezers. And because we've all been there, perhaps it's time to take a refresher course or improve your tools if you're having trouble. 

4. Wrong Lash + Wrong Lash = Trouble

A weak natural lash may become overloaded if a thick or heavy extension is applied. At first, it might not be apparent, but after a day or two, it disappears.

What is more effective:
  • Align the weight of your lashes with their natural health.
  • Make use of light, fluffy fans that are either handmade or Promade.
  • When in doubt, choose lighter lashes since they stay healthier and have better retention.

5. Adhesive Timing Is Everything

The lash simply won't attach if it is applied too late (already semi-dry) or too early (wet adhesive). It requires practice to become proficient at timing your dip-to-place rhythm.

A quick test: Does the fan "wrap and hug" the natural lash when it is in place? or simply perch atop? Try to get the former. The timing is incorrect if it pops off or slides about.

6. Client Habits Make a Difference

It's difficult since you have no control over it. Frequently, clients who avoid aftercare, sleep face down, or touch their eyes are inadvertently undermining your efforts.

Good communication makes a big difference.

Provide gentle reminders rather than reprimands:
  • Consider using a silk pillowcase or sleeping on your back.
  • Stay away from saunas and hot steam for 24 to 48 hours.
  • Use a lash-safe cleaner to clean your lashes every day.
When lashes don't stick, it's easy to lose hope. However, instead of descending into self-doubt, take use of it as a teaching opportunity. The surroundings might be the cause at times. Occasionally, it's the method. At times, it's simply life.

How you react—with compassion, curiosity, and a dedication to honing your craft—is what counts.

Because ultimately, you're doing more than just applying eyelashes; you're fostering beauty, establishing trust, and assisting someone in feeling their best.

And that? That endures.
