Lash Fills vs. Full Sets – Understanding the Difference
If you’ve been searching for eyelash extensions in Calgary or considering enhancing your lashes for the first time, you’ve probably come across the terms “full set” and “lash fill.” At first glance, they may sound similar—but they’re two very different services.
Whether you're getting ready for a big event, want to simplify your beauty routine, or you're just curious about how lash extensions work, understanding the difference between a full set and a fill will help you make the right decision for your lifestyle, budget, and natural lash health.
What Are Eyelash Extensions?
Eyelash extensions are semi-permanent fibers that are carefully applied to your natural lashes using a special adhesive. They add length, fullness, and definition, eliminating the need for mascara or strip lashes.
They come in various styles, lengths, curls, and thicknesses—and can be customized for a natural or bold look. If you’ve been searching for “eyelash extensions Calgary,” chances are you’ve already seen how different they can look depending on the lash artist and technique used.
But here’s the thing: eyelash extensions require maintenance, just like your hair or nails. That’s where lash fills come in.
What Is a Full Set of Eyelash Extensions?
A full set is your starting point. During this appointment, your lash artist will apply extensions to nearly every healthy natural lash you have. This can take anywhere from 90 minutes to 2.5 hours, depending on the style and how many natural lashes you have.
When to Book a Full Set:
You’re getting eyelash extensions for the first time.
Your previous set has completely shed or been removed.
You want a new style, curl, or volume level.
Your lashes have had a long break and need a fresh application.
What to Expect:
A thorough consultation to discuss your desired style.
Customized lash mapping based on your eye shape and lash health.
A relaxing, detailed application process.
Aftercare instructions for best retention.
Full sets can range in price depending on the style (classic, hybrid, volume, or mega volume), but they are typically the most expensive lash service, as they require the most time and product.
What Is a Lash Fill?
A lash fill is a maintenance service that helps keep your lash extensions looking fresh and full. Your natural lashes go through a shedding cycle, and you lose 2–5 lashes per eye, per day. That means, over time, your extensions will start to look sparse.
During a fill appointment, your lash artist will:
Remove outgrown or loose extensions.
Replace fallen lashes with new ones.
Cleanse the lash line and check lash health.
Fills typically take 45 to 75 minutes, and most clients return every 2 to 3 weeks to maintain their look.
When to Book a Lash Fill:
You still have at least 40–50% of your extensions left.
It's been 2–3 weeks since your last appointment.
You want to keep your lash line looking full without booking a full set.
Lash Fills vs. Full Sets – What’s the Real Difference?
Here’s a quick breakdown of the key differences:
If you’ve had a lash break, switched styles, or waited too long between appointments, you may need to book a full set instead of a fill.
How Canada’s Climate Affects Lash Retention
If you're living in Calgary or anywhere across Canada, you know that our changing weather can wreak havoc on skin and hair—and yes, even lashes.
Dry winter air can cause adhesive to cure too quickly, reducing bond strength.
Humidity changes in spring and summer can affect retention and application time.
Dry skin and oils around the eyes (especially from rich creams) can break down lash glue faster.
Tips for Better Retention in Canadian Climates:
Use oil-free cleansers and moisturizers around the eyes.
Avoid heavy eye creams that can loosen the bond.
Clean your lashes daily with a lash-safe cleanser to remove debris and oil.
Book lash fills every 2–3 weeks to keep your set fresh and even.
How to Know Which Service You Need
If you’re unsure whether to book a full set or a lash fill, here are a few questions to ask yourself:
Has it been more than 3 weeks since your last lash appointment?
Do you have less than 40% of your extensions remaining?
Are you changing lash styles or going to a new artist?
If you answered yes to any of these, it's likely time for a new full set. Otherwise, a fill should be just right.
The Bottom Line
Both lash fills and full sets are essential parts of maintaining beautiful, long-lasting lash extensions. A full set gets you started, and fills help you keep the look going strong.
By staying consistent with your appointments and adjusting your aftercare for Calgary’s dry, shifting climate, you can enjoy fuller, longer lashes without the daily hassle of mascara or strip lashes.
