Once you've found a lash look you love, there's one question that eventually comes up:
What happens when you start running out of lashes?
If you already have your application tools and lash essentials at home, buying another complete starter kit every time you need more clusters doesn't necessarily make sense.
That's where lash infills and lash refills come in.
For DIY lash wearers, infills can offer a simple way to replenish the lash clusters you use most without replacing all the tools and products you already own.
But the term lash infill can also refer to a completely different process at a professional lash salon.
So what exactly are lash infills, when do you need them, and should you buy an infill pack or another complete lash kit?
Let's break it down.
What Are Lash Infills?
Traditionally, a lash infill refers to a maintenance appointment for professional eyelash extensions.
As natural lashes shed and new lashes grow, some extensions are naturally lost with them. During an infill appointment, a lash technician assesses the remaining extensions and adds new ones where appropriate to restore the appearance of the set.
With DIY cluster lashes, however, the concept works differently.
Instead of booking another appointment, a DIY lash infill or refill can simply mean replenishing your supply of lash clusters once you've already purchased the tools and products needed to apply them.
You keep your existing application system.
You simply replace the lashes you need.
What's the Difference Between Lash Infills and Lash Refills?
You'll often see terms such as lash infills, lash refills, cluster lash refills and lash cluster infills used when shopping for lashes.
For DIY systems, they can describe essentially the same purchasing idea:
More lashes without purchasing another complete starter kit.
The terminology varies between brands.
What's more important is understanding what's actually included in the product you're buying.
A complete starter kit may include lashes plus application and removal essentials, while an infill or refill product may primarily replenish the lash clusters themselves.
Always check the individual product description so you know exactly what is included.
When Do You Need Lash Infills?
There's no universal schedule for buying DIY lash infills.
How quickly you need more clusters depends on factors such as:
-
how frequently you wear lashes
-
how many clusters you use per application
-
the lash styles and lengths you prefer
-
whether your particular lashes remain suitable for reuse
-
how carefully they're removed and cared for
Someone who wears DIY lashes regularly will naturally work through their lash supply faster than someone who only wears them for weekends or special occasions.
Rather than buying infills according to a fixed calendar, it makes more sense to monitor your lash tray.
When you're beginning to run low on the clusters you regularly use, it's probably time to replenish them.

But once you already own your application tools and supporting products, you don't necessarily need another complete kit simply because you're running low on lashes.
That's where D’Lumin Lash Infills come in.
They allow existing D’Lumin users to replenish their lash supply while continuing to use the application essentials they already have.

If you're starting from scratch, choose the Starter Kit.
If you already have your D’Lumin system and simply need more lashes, choose Infills.
How Often Should You Buy Lash Infills?
There's no need to replace your lash supply according to an arbitrary schedule.
A better approach is to base your purchase on how quickly you personally use your clusters.
For example, someone who wears clusters continuously may need to replenish their supply considerably sooner than someone who applies them occasionally.
Wear time also matters.
D’Lumin lashes are designed for approximately 5–7 days of average wear per application, although individual results can vary depending on application, lifestyle and aftercare.
We've covered the factors affecting wear in much more detail in our guide to how long cluster lashes last.
Reusability may also affect how quickly you work through your supply.

Hybrid vs Volume Lash Infills: Which Should You Choose?
Your refill isn't just about replacing lashes.
It's also an opportunity to choose the look you want to create next.
D’Lumin offers different lash styles so you can adjust the overall effect depending on your preference.
Hybrid lashes are a great choice when you want a balanced look combining definition and fullness.
Volume lashes create a fuller, more noticeable lash effect when you want additional impact.
You may find yourself naturally favouring one style.
Or you can keep both available and choose according to your mood, makeup or occasion.
That's one of the advantages of applying cluster lashes yourself: you're not locked into the same lash look every day.
Can Lash Clusters Be Reused Before You Buy Infills?
Potentially, depending on the lash design, their condition after removal and the instructions for the particular product you're using.
A lash cluster should never be reused simply because you want to stretch it further.
Its condition matters.
Careful removal can help avoid unnecessarily damaging clusters, while improper removal may make them unsuitable for another application.
If you're planning to reuse your clusters, follow the appropriate removal and care instructions and inspect them before reapplication.
We've created a complete guide specifically about this:
That article explains the factors that determine whether a cluster may be suitable for another application.
Are Pre-Glued Lash Refills Different?
Pre-glued lash clusters have adhesive already applied to the lash band.
That can make the initial application particularly convenient because you don't necessarily need to separately apply bond during that first application.
When purchasing pre-glued lash refills, you're essentially replenishing those ready-to-apply clusters rather than purchasing another complete set of application tools.
Different lash systems work differently, though, so always follow the instructions supplied with the particular lashes you're using.
With the D’Lumin system, the initial application is designed around pre-glued clusters, while the Professional Bond & Seal included in the Starter Kit supports subsequent applications.
How Can You Make Your Lash Supply Last Longer?
Getting better value from your lashes isn't about trying to keep every cluster forever.
It's about taking proper care of the products you have.
A few simple habits can help:
-
remove lashes gently rather than pulling
-
use the appropriate remover
-
handle clusters carefully with your application tool
-
keep unused lashes clean and protected
-
avoid unnecessarily touching the lash bands
-
store your lash products properly
-
only reuse clusters when they're still suitable to be reapplied
Good application and aftercare can also affect how long your lashes remain in place.
If you're having trouble getting the wear time you expect, read our guide to how long cluster lashes last before assuming you simply need more lashes.
Are DIY Lash Infills Cheaper Than Salon Infills?
They're two very different products.
A professional salon infill is a service performed by a lash technician.
You're paying for the technician's time, expertise, materials and appointment.
A DIY lash infill or refill is generally a product that replenishes lashes you apply yourself.
So rather than repeatedly paying for professional application, you're replenishing the component of your DIY lash system that you actually use up.
For someone comfortable applying their own clusters, this can make DIY lashes an attractive alternative to the ongoing appointment cycle associated with salon extensions.

Lash Infills Make DIY Lashes Even More Flexible
One of the biggest advantages of a DIY lash routine is control.
You decide when to apply your lashes.

You decide whether you want a softer Hybrid look or something fuller.

You simply replenish what you need.
