Lash retention tips for lash artists: how to keep your lashes flawless for longer

If you've ever wondered why some lash extensions last forever while others fall out in days, you're not alone. Lash retention is extremely important for client satisfaction, lash health, and repeat appointments, and it should be taken seriously by both lash artists and clients.

If you're looking for lash retention tips, you're in the right place. You'll learn pro-tested retention strategies for beginners and advanced artists alike. These expert lash retention tips will help you achieve better, longer-lasting results every time.

What is lash retention?

Lash retention refers to how long your eyelash extensions last before falling out, either naturally or prematurely. Ideally, lash extensions should stay in place until your natural lash completes its growth cycle and sheds on its own. That’s considered good retention.

On the other hand, poor retention causes your extensions to fall off much sooner (sometimes just days after application), resulting in gaps, frustration, and disappointed clients.

There are several factors that influence lash retention (don't worry, we'll get to those soon), but one thing is certain: understanding what affects retention and how to improve it is the key to longer-lasting lashes and satisfied clients who return.

Lash retention checklist

Here are 12 expert-approved tips to help improve lash retention, from adhesive selection to client aftercare:

1. Choose the right lash adhesive
2. Ensure the adhesive is fresh and properly stored
3. Shake your eyelash glue before use
4. Control the lash room environment (temperature, humidity)
5. Thoroughly clean and prime natural lashes
6. Use appropriate base attachment and placement techniques
7. Isolate natural lashes precisely
8. Apply the right amount of adhesive
9. Avoid overly heavy extensions
10. Shock cure or seal the bond after application
11. Educate clients on the aftercare routine
12. Schedule regular infills

1. Choose the right lash adhesive

Lash glue isn’t one-size-fits-all. For the best lash retention, use an adhesive that matches your environment and speed. If you need to work quickly and have maximum hold, choose a quick-drying formula. Consider flexible options for clients with sensitive skin or fluctuating humidity levels.

Looking for the next level of retention? Our Magnet UV Lash Glue provides a stronger bond while emitting fewer fumes, making it ideal for long-lasting results with minimal irritation. Choosing the right glue makes all the difference in how well your lashes stay put.

2. Ensure fresh, properly stored adhesive

Even the best glue will fail if it is old or stored improperly. Once opened, the lash adhesive should be replaced every 4-6 weeks and stored upright in a cool, dry place. Avoid extreme temperatures, such as hot rooms and cold windowsills!

To extend its life, store it in an airtight container or glue storage capsule. Fresh glue results in stronger bonds, faster curing, and, ultimately, better lash retention. If you're unsure about your adhesive's shelf life, it's probably time to replace it.

3. Shake your eyelash glue before use

It might seem like a small step, but shaking your adhesive properly is crucial. Lash glue contains a number of ingredients that can separate if left standing. If you don't shake your glue, it won't perform properly, resulting in weak bonds and low retention. Use a glue shaker or shake by hand for at least 30-60 seconds before each use. 

Pro tip: shake your glue before placing each new drop to ensure consistent results throughout the treatment.

4. Control lash room environment (temperature & humidity)

Your lash glue is picky; it works best in a specific temperature and humidity range. Too dry or too humid, and it won't cure properly, resulting in poor lash retention. Always keep a hygrometer in your room and use a humidifier or dehumidifier as needed.

Most adhesives perform best between 21-23°C and 45-60% humidity, but check your glue's exact specifications. A stable lash room = more consistent and longer-lasting results for your clients.

5. Thoroughly cleanse & prime natural lashes

Clean lashes are happy lashes! Starting with a clean slate is one of the most straightforward ways to improve lash retention. Always start by thoroughly cleansing your client's natural lashes with a gentle, oil-free lash shampoo, such as our Eyelash Foam Cleanser. This removes any makeup, oils, or debris that may weaken the bond.

After cleaning the lashes thoroughly, apply a high-quality primer to ensure maximum adhesion. Skipping this step may result in early lash fallout, so take the time; it only takes a few minutes and lays the groundwork for stronger, longer-lasting results.

6. Use proper base attachment & placement techniques

The way you place each lash extension can make or break your retention. Always keep the extension 1-2 mm away from the skin and securely bond it to the natural lash base. Ensure that the extension's base completely hugs the natural lash, without tilting or hovering in the middle shaft. Incorrect placement (too far from the lash line or on the tip) can result in poor retention or discomfort. 

Remember that proper attachment is more than just precision; it is about promoting natural lash growth and ensuring that each extension stays in place until the lash sheds naturally.

7. Isolate natural lashes accurately

Lash isolation may seem tedious, but it is one of the most important steps for good retention. When you properly isolate each lash, you ensure that the extension only bonds with one natural lash. This prevents "stickies," in which multiple lashes are glued together, causing discomfort and premature shedding.

Use tweezers with precision and take your time. Even if it slows you down slightly, the reward is worthwhile. Proper isolation improves retention and lash health, both of which are essential components of a flawless lash set.

8. Apply the right amount of adhesive

Finding the optimal glue balance is key. Using too much adhesive results in heavy, clumpy bonds that may not cure evenly. Too little and the lashes will fall out prematurely. Aim for a thin, even layer that is just enough to completely cover the base of the extension without forming beads.

The adhesive should wrap around the natural lash for optimal grip. Every 15-20 minutes, apply a fresh glue drop and evenly dip the lash base. When attempting to achieve perfect lash retention, consistency of technique and adhesive control are essential.

9. Avoid overly heavy extensions

Choosing the right weight and length matters more than you think. If your client's extensions are too long or heavy for her natural lashes, they can cause strain, poor retention, and even lash damage. Always assess the lash line before selecting extensions.

Depending on the client's lash strength, use lighter weights of 0.10 mm for classic and 0.05 mm for volume sets. It's all about striking a balance between giving clients the glam they want and preserving their natural lashes for long-lasting results.

10. Shock cure or seal the bond after application

Finish your set with a curing solution like Instant Cure to lock in all of your hard work. This retention-boosting mist instantly polymerizes the adhesive, sealing it and reducing exposure to humidity and pollutants. It also reduces fumes, which makes the experience more pleasant for sensitive clients.

To achieve the best results, apply two minutes after completing the set. It's a simple step that improves retention, reduces lash shedding, and allows your clients to go about their day without fear of water or steam.

11. Educate clients on aftercare routine

Retention does not stop at the salon. Prepare your clients for success by clearly explaining aftercare. Inform them to avoid steam, saunas, oil-based products, and rubbing their eyes, especially within the first 24-48 hours. Encourage daily cleansing with oil-free lash shampoo and brushing with a clean spoolie.

Good habits help extensions last longer by preventing infection or buildup. Send them home with a digital or printed care guide, and don't forget to read our eyelash extension aftercare tips for more useful advice.

12. Schedule regular infills / fills

Even the best lash sets lose volume over time. Natural lashes shed in cycles, so clients need infills every 2-3 weeks to keep their lashes looking fresh and full. Waiting longer results in gaps, unbalanced sets, and a longer next appointment.

Regular infills improve both appearance and retention, ensuring that your clients receive consistent results and that your schedule remains predictable. Send reminders and educate clients about the importance of infills.

Bonus: pre- and post-appointment tips

• Timing matters: If your client has recently had a facial or skincare treatment, particularly one that involved oils or steam, they should wait 24-48 hours before scheduling a lash appointment. These treatments may leave residue on the skin and lashes, weakening adhesive bonds.

• Avoid caffeine before appointments because it can cause fluttery eyes and make lash application more difficult, potentially jeopardizing lash isolation and placement.

• Post-treatment tip: For better retention between fills, suggest clients sleep on their backs or use a silk pillowcase. It reduces friction, which can cause premature lash loss.

• Retail add-on idea: Providing your own mini aftercare kit (including a cleanser, spoolie, and instruction card) reinforces good habits and builds trust, and it looks great on your retail shelf!
