Here's what I wish I knew before getting eyelash extensions: I wish I knew about all of the shapes and sizes, and how to know which one would fit me!
“Lash extensions seemed like an easy win — until I realized I didn’t know what I was getting into.” If you've ever said something like that, you’re not alone. Eyelash extensions are a beauty game-changer, but they come with surprises. Some are great. Others? Not so much.
Whether you’re thinking about getting lash extensions for the first time or you already have them and want them to last longer, this article will help. We’re covering everything I wish I knew before I got mine — including the products, prep, care, and common mistakes.
Lash Extensions Aren’t One-Size-Fits-All
One of the biggest surprises? There’s more than one type of eyelash extension.
There are different curls (like C, D, or L curl), different materials, and different techniques — classic, volume, or hybrid. Some give you a natural boost. Others add full glam.

Good Glue Matters More Than You Think
Your lash glue is just as important as the lashes themselves. A cheap adhesive won’t hold, can irritate your eyes, and might ruin your natural lashes.
I learned (the hard way) that professional-grade glue like the Royal Eyelash Extension Glue is worth every penny. It holds for weeks, works even in humid places, and doesn't fall apart after a day or two.
Here are a few other great options:

Prep Is Everything — But Most People Skip It
Most of the issues I had early on came from poor prep. Your lashes need to be super clean, oil-free, and dry before applying extensions.
Here’s what helps:
-
Use Lash Wash to gently clean your lashes before every fill or appointment
-
Follow up with a Primer Without Perfume to remove oils and create a good bonding surface
-
Avoid heavy eye creams or oily makeup that day
A good primer sets the stage for long-lasting retention. A bad prep means your lashes may start falling off within hours.
Extensions Don’t Damage Your Natural Lashes — If You Do It Right
People often say, “lash extensions ruined my lashes.” That’s not totally fair. Most of the time, it’s bad glue, bad technique, or pulling them off that does the damage.
If you need to remove lashes, use a product like Remover Cream - Sensitive instead of picking at them. Pulling extensions off rips out your natural lashes and can lead to patchy regrowth.
This post — How to Remove Eyelash Glue — shows you how to do it safely.
They Feel Weird at First (But You’ll Adjust)
When I first got extensions, I was hyper-aware of them. It felt like something was sitting on my eyelids 24/7. But within a couple of days, I forgot they were even there.
Expect a short adjustment period. During that time:
-
Don’t rub your eyes
-
Avoid steam and hot showers for at least 24 hours
-
Sleep on your back if you can
They Take Maintenance
Extensions are a time-saver in the morning, but they’re not totally low-maintenance. You’ll need to:
-
Clean them with Lash Wash 2-3 times a week
-
Avoid mascara (especially waterproof)
-
Get a fill every 2-3 weeks
A little daily care goes a long way. Seal your lashes with an Eyelash Extension Sealer if you want to protect your investment and keep them fresh longer.
Climate and Lifestyle Matter More Than You Think
If you live in a humid place, your glue needs to work with that. Elite Eyelash Extension Glue is great for warmer, stickier climates. If you work out often, swim, or sweat a lot, go with something that has high retention power like Ideal Eyelash Extension Glue.
Also, avoid oil-based cleansers and makeup removers. They break down the glue.
Choose the Right Lash Artist
This one matters the most.
Your lash artist should walk you through everything, ask about allergies, and explain aftercare. If they rush you, use too much glue, or don’t clean your lashes first — that’s a red flag.
Check reviews. Ask to see before-and-after photos. And if your eyes burn during or after your appointment, that’s not normal. You can read more about glue safety in this post: Is Lash Glue Safe to Use?
Know the Difference Between Lash Glue and Lash Adhesive
These terms are often used interchangeably, but technically, there’s a difference. This blog explains it, and it’s worth reading if you’re curious.
Bottom line: not all adhesives are created equal. Choose one that’s designed for professional extensions — not strip lashes or DIY kits.
You Can Be Allergic to Lash Glue
Most people aren’t allergic, but it happens. If your eyes swell, turn red, or get itchy after application, you could be reacting to the glue. This is why sensitive options like Pure Eyelash Extension Glue are a must-have for some clients.
If you have sensitive skin or are prone to allergies, do a patch test first. Talk to your lash artist about ingredients.

Final Tip: Do Your Research First
Lash extensions are awesome when done right. But if you go in without knowing the basics, you’ll waste money, damage your lashes, and walk away frustrated.
Take time to learn. Choose quality products. Work with professionals who know what they’re doing.
