How to Improve Lash Retention: The 5-Step System Every Lash Tech Should Follow’

Lash retention is the holy grail for every lash artist. Clients might not know the science behind adhesives or humidity levels, but they definitely notice when their lashes don’t last. 

Poor retention leads to frustrated clients, awkward “Can you squeeze me in for a touch-up?” texts, and your reputation taking the hit. But great retention? That’s what makes clients loyal, rebooking on repeat, and raving about you to all their friends.

If you’ve already nailed the basics, clean lashes, proper humidity, high-quality adhesive, it’s time to level up. This isn’t just another “wash the lashes” reminder. This is a 5-step lash retention system with advanced, practical tips you can start using right away.

Step 1: Keep Lash Prep Simple (But Powerful)

More products don’t automatically mean better retention. In fact, overloading lashes with too many pre-treatment steps can work against you. What clients really need? Clean, perfectly prepped lashes, and nothing extra that gets in the way.

Here’s your prep checklist:

• Start with a thorough cleanse. Get rid of oils, proteins, and makeup residue.

• Test how extensions adhere before adding anything else.

• Don’t use primer or booster by default, if the client’s natural lashes are already in great condition, less is more.

• Stick to one prep product that consistently gives you the best results.

This approach keeps natural lashes balanced, helps adhesive bond properly, and saves you time without compromising retention.

Step 2: Check Your Work From Every Angle

You’ve finished a set, it looks great from the front, and you’re ready to take a picture. But here’s the thing: retention issues often hide in the angles you don’t look at.

Before calling it done:

• Tilt your head or use tweezers to gently shift the lashes sideways.

• Double-check that every extension is fully bonded, not just sitting pretty.

• Pay extra attention if you apply from the top down, the underside is where sneaky attachment flaws like to hide.

That extra check makes the difference between lashes that fall out too soon and lashes that keep clients booking refills right on schedule.

Step 3: Track Retention for Each Client

Every client is unique. What works perfectly for one person might flop for another. Lifestyle, hormones, diet, or even skincare routines can all impact lash longevity. That’s why tracking retention is such a game changer.

Make it part of your client file to note things like:

• Which glue and lash type you used

• What you observed (oily lids, brittle natural lashes, etc.)

• Any lifestyle changes (new meds, workouts, skincare) that could affect retention

Not only does this help you troubleshoot and tailor your approach, but it also shows clients you’re paying attention to their lashes, not just lashes in general. That kind of care builds trust, and loyalty.

Step 4: Recommend the Right Aftercare Products

Let’s be real: retention doesn’t live and die in your lash room. Clients have to do their part at home. That’s where retail comes in, not just as a sales boost, but as an extension of your service.

Stock and recommend essentials like:

• Oil-free lash cleansers – to keep lashes fresh without weakening the adhesive

• Sealants or gels – to lock in bonds and protect against everyday wear

• Brushes/spoolies – for daily maintenance

The key isn’t just handing them a product. It’s showing them why it matters. Once clients understand that aftercare = better lash retention, they’re more likely to follow through, and you’ll see it in their refills.

Step 5: Control Your Environment Like a Pro

Even flawless technique can flop if your environment is working against you. Adhesives are picky, they need the right conditions to perform at their best.

Always monitor:

• Humidity: Keep it in that sweet spot (usually 40–60%).

• Temperature: Avoid extremes; glue doesn’t like surprises.

• Adhesive freshness: Refresh glue drops every 20–30 minutes and store unopened bottles properly.
  

Consistency in your lash room = consistency in your retention results. Period.
