❌ Myth: More glue = better retention
✅ Truth:
Using too much adhesive can actually reduce retention.
A properly sized adhesive bead cures evenly and creates a strong bond. Too much adhesive:
-
Takes longer to fully cure.
-
Can become brittle or create a bulky bond.
-
Increases the chance of stickies.
-
Adds unnecessary weight to the natural lash.
Lash Savvy Tip:
Aim for a small, smooth bead that lightly coats the extension's base. The extension should "wrap" the natural lash with just enough adhesive—not a visible blob.
❌ Myth: Refrigerating glue fixes everything
✅ Truth:
Refrigeration doesn't revive old or degraded adhesive.
Keeping unopened adhesive cool can help slow aging, but refrigeration isn't required by every manufacturer. If you refrigerate it:
-
Keep it sealed in an airtight container with a desiccant packet.
-
Allow it to return completely to room temperature before opening to prevent condensation inside the bottle.
Once adhesive has thickened from age or moisture exposure, refrigeration will not restore its original performance.
Lash Savvy Tip:
For everyday use, store adhesive upright in a cool, dry place away from sunlight. Opened bottles are best replaced within their recommended use period (often around 6–8 weeks, depending on the product and storage conditions).
❌ Myth: Faster drying glue is always better
✅ Truth:
The best drying speed is the one that matches your application speed.
If an adhesive cures faster than you can place the extension:
-
It may begin curing before full contact.
-
Bonds can be weaker.
-
Retention may suffer.
If it cures too slowly:
-
Extensions can shift.
-
Stickies become more likely.
-
Application may take longer.
Lash Savvy Tip:
Choose an adhesive that matches both your experience level and your room's humidity and temperature. A "faster" adhesive isn't automatically a "better" adhesive.
❌ Myth: Humidity doesn't matter
✅ Truth:
Humidity is one of the most important factors affecting cyanoacrylate adhesive performance.
Cyanoacrylate cures by reacting with moisture in the air.
If humidity is too low:
-
Adhesive cures more slowly.
-
Bonding may be incomplete.
-
Retention can decrease.
If humidity is too high:
-
Adhesive may cure too quickly.
-
Less time for proper placement.
-
Shock curing or blooming can occur in some situations.
Lash Savvy Tip:
Use a hygrometer to monitor your room and choose an adhesive designed for your typical humidity range.
❌ Myth: Shaking for 5 seconds is enough
✅ Truth:
Five seconds often isn't enough to fully mix the ingredients.
Adhesives contain ingredients that can separate during storage, including pigments and stabilizers. Inadequate mixing can lead to inconsistent viscosity and performance.
Many manufacturers recommend shaking for 1–2 minutes before first use of the day and about 20–30 seconds before each subsequent glue drop (always follow the specific manufacturer's instructions if they differ).
Lash Savvy Tip:
Shake thoroughly, wipe the nozzle after dispensing, and burp the bottle if recommended for your packaging before replacing the cap tightly.
Bonus Myth
❌ Myth: If my retention is poor, I need a stronger glue.
✅ Truth:
Most retention issues are caused by application technique or environmental factors, not adhesive strength.
Common causes include:
-
Dirty natural lashes.
-
Incorrect humidity or temperature.
-
Too much or too little adhesive.
-
Poor isolation.
-
Improper placement or wrapping.
-
Old adhesive.
-
Slow pickup-to-placement time.
Lash Savvy Tip:
Before switching adhesives, evaluate your environment, adhesive freshness, and application technique. A consistent setup often improves retention more than changing to a different formula.
