Top Tips for Lash Technicians During an Eyelash Extension Infill


When it’s time to infill a client’s lashes, it can feel a bit daunting. Don’t stress – we’ve got your back! With a few key rules and handy tips, infills will soon become second nature and a nice break from full eyelash extension sets.

Setting Yourself Up For Success

First off, always give yourself enough time. If you're just starting out, schedule at least an hour and a half for each infill appointment. Don't worry if you need more time – it's not a race!

Encourage clients to book their infill appointment at the end of their full eyelash extension treatment. This way, you avoid long gaps between infills. Don’t schedule infills more than three weeks after the full set, and let clients know they should have at least 50% of the lash extensions still attached for their infill.

Emphasize the importance of proper eyelash extension aftercare. Clients should clean their lashes daily with a specially formulated Lash Shampoo and Cleansing Lash Brush. Applying lash extensions to dirty lashes can be very frustrating. Encourage proper aftercare by selling your own aftercare kits and providing an Aftercare Leaflet at the end of each appointment to teach them how to look after their new lashes.


Squeaky Clean Lashes!

Even after advising your client about the importance of aftercare, there will always be someone who comes in with dirty lashes. Be prepared by keeping Lash Shampoo and Cleansing Lash Brushes handy so you can clean their lashes before starting. This is also a great opportunity to demonstrate proper lash care.

Once the lashes are clean, you’re ready to apply the under eye patches.

Removing Unwanted Lashes

Next, remove any lash extensions that make the set look messy. These are usually lashes that have grown out more than 3mm or have twisted.

The quickest method is the 'Banana Peel Method' using your eyelash tweezers. Hold the natural lash with one pair of tweezers and the extension with another, then gently peel off the extension.

If the lash glue is too strong, use a small amount of eyelash extension remover directly on the lash extension to dissolve the glue.

Another way to remove grown-out lash extensions is by pinching the bottom of the extension to break the glue bond between the natural lash and the extension.

Talk to your client about how their extensions felt and if there's anything they’d like to improve. Feedback helps you become more efficient and improve your technique.

An infill is also a good time to check your work and correct any mistakes from the previous set, like any stickies or poorly applied lashes.

It's Time to Apply New Lashes!

We’re at the final step. Before applying new extensions, use Cleanser and Primer pre-treatment on the natural lashes with Micro Fiber Lash Brushes, just like you would for a full set. Check out this blog for more details on the perfect pre-treatment routine.

If you're a beginner, you might feel more confident by repeating the lash mapping process before applying new extensions. Do whatever makes you feel comfortable!

You might notice one lash line is fuller than the other. This could be due to various reasons, like the side your client sleeps on or if they touch one eye more often. This is normal.

When dealing with an uneven infill, start with the eye that has fewer extensions until they are even. Then, continue applying new lashes to both eyes as you normally would.

Infill appointments can be smooth and stress-free with a bit of preparation and these savvy tips. Communication with your clients is crucial to understand their needs and expectations. By following these tips, you'll have more efficient infill appointments and happier clients!
