Eyelash Extensions: Everything You Need to Know

Full, long, dark lashes every single day without needing coats of waterproof mascara? Um, yes, please.

And if you’re anything like me, you’ve probably also contemplated getting lash extensions a thousand times (for the record, I highly recommend it). But before you book an appointment, you need to educate yourself on the good, the bad, and the annoying aspects of having selfie-ready lashes.  Keep reading for all the details you seriously need to know. 

Are lash extensions worth it?

Unlike gluing a strip of temporary fake lashes onto your lash line, semi-permanent lashes are applied by a technician who hand-glues the extensions on top of your natural lashes.  Because lash extensions don’t come in a strip, they are super customizable and actually look real. With proper care (more on that later), they can last for six to eight weeks until they naturally fall out like your lashes usually do.

Do eyelash extensions ruin your natural lashes?


There isn’t much evidence that shows whether eyelash extensions actually affect your natural lash length or health long-term. It usually takes years of bad application and improper care for long-term lash damage to happen as a result. So please, only go to reputable, well-reviewed salons (no matter how good that Groupon deal is), and make sure your technician washes their hands between clients, wears a mask, uses sanitary pillow covers, sterilizes their tweezers, and uses disposable eyelash brushes. And yes, you are allowed to ask your technician to confirm all these things.

How do you know what size eyelash extensions to get?

So, you want Kim Kardashian–level lashes? Great—but that doesn’t mean your eyes can handle them. The type of lashes you can get all depends on the length and strength of your natural lashes. Wearing lashes that are too long or too thick for your lashes can actually cause damage in the long run, so you need to make sure your extensions aren’t too much longer or thicker than your natural lashes.

If all that sounds confusing, don’t freak—a licensed lash specialist will help you make the best decision for your lashes, including what type of material you should get, like synthetic mink or synthetic silk. Mink is usually pricier, feels softer, and looks more natural; however, some synthetics, which are highly customizable, can also look and feel natural and end up costing as much as or more than mink. 

When it comes to density, curl, and length of your extensions, you’ll want to work with your tech to figure out which is the best option for you.

Can I swim or shower with my eyelash extensions?

You can, but not until you’ve waited at least 24 hours after your appointment. Eyelash adhesives vary in the time they take to cure, from either 12 to 24 hour depending on what glue your stylist uses. It’s super important that you’re gentle with your lashes and make sure that no water touches them during this time. You can shower after getting lashes as long as you don’t get the lashes wet and don’t stay in the steam for too long.

Can you wear eye makeup with eyelash extensions?

We don’t recommend using mascara with lash extensions. Why? Because when you attempt to take it off at the end of the day, you can actually cause your extensions to break from the friction and makeup remover. As for eyeliner, avoid using cream-based formulas. They often contain oils and waxes that can break down lash glue.

Can you wash your eyes with eyelash extensions?

Only use cleansers specifically formulated to be safe for eyelash extensions. Other products may contain ingredients that can weaken the bond of your lash extensions and cause them to shed prematurely. And if you’re wearing eye makeup, use oil-free pads and gently swipe downward, rather than back and forth, to get your lids and lashes clean. And whatever you do, avoid rubbing or tugging at your eyes.

Should you brush your lash extensions?

Lashes can get tangled when you’re sleeping or showering, so it’s required that you gently brush your lashes with a clean spoolie brush when you wake up, after you shower, and at the end of the day. 

Okay, so there’s a lot to think about before you decide to get eyelash extensions. If you feel like mascara isn’t totally cutting it and you’re okay with the extra maintenance and cash that eyelash extensions require, it’s definitely worth finding a specialist and having a consultation.
