How To Improve Lash Retention?

Expert tips every lash artist should know!

If you're a lash technician or salon owner, you've probably heard this:
“My lashes didn’t last as long this time—what happened?”

Lash retention—how long eyelash extensions stay in place—is critical to client satisfaction. Fortunately, improving retention is entirely possible when you combine the right techniques, products, and environmental control.

Here’s a breakdown of London Lash expert-backed steps to help you maximize eyelash retention—plus the professional tools that make all the difference.

1. Start With a Flawless Prep Routine

Great retention begins with perfectly clean natural lashes. Oil, dust, and makeup residue are major culprits behind poor adhesion.

• Use a lash cleanser to thoroughly clean the lash line.
  
  

• Apply a primer to balance pH and increase glue grip.
  
  

• Dry completely before application.
  
  

London Lash Cleanser & Primer Duo is professional-grade set preps lashes with a gentle yet effective formula that increases adhesion without drying out the natural lash. A must-have in any pro kit.

2. Match Adhesive to Your Room Conditions

Temperature and humidity affect how your adhesive cures. Using the wrong glue for your environment is one of the most common causes of lash fallout.

• Use fast-curing glues in higher humidity.
  
  

• Choose slower-drying options in drier climates.
  
  

• Track room conditions with a hygrometer.
  
  

London Lash Power Bond Adhesive - Formulated to work in a wide humidity range (30–70%) and with a drying time of just 0.5–1 second, Power Bond is a favourite among professionals who need reliable retention and fast application. Perfect for both volume and classic lash sets.

3. Fine-Tune Your Application Technique

Application is where art meets science—and retention is won or lost.

• Isolate lashes thoroughly to avoid stickies.
  
  

• Use a consistent glue bead—too little = weak bond, too much = excess weight.
  
  

• Dip straight into the glue, don’t swipe.
  
  

4. Control the Curing Process

Lash adhesives cure using moisture in the air. If that process is too fast or too slow, the bond will weaken.

• Use a nano mister to assist curing.
  
  

• Apply a London Lash superbonder at the end to reduce fumes and lock in retention.
  
  

• Avoid drafts from fans or open windows that can shock-cure the glue.
  
  

Bonus: A bonder can also allow clients to get their lashes wet the same day, increasing comfort and convenience.

5. Coach Clients on Proper Aftercare

Even perfect applications can’t stand up to poor aftercare.

Educate your clients to:

• Clean lashes daily with an oil-free lash foam
  
  

• Avoid oil-based skincare and makeup removers
  
  

• Refrain from rubbing or sleeping face-down
  
  

• Book infills every 2–3 weeks
  
  

Consider retailing a gentle lash cleanser and brush set to support aftercare between appointments.
