All There is to Know About Eyelash Extensions

Eyelash extensions are a great option for those wanting to elevate an eye look for more than just a night. They last anywhere from six to eight weeks and make it so that you don’t even really need eye makeup.

Upkeep isn’t too taxing either (thank the beauty gods for that), but there are some general rules to keep in mind. We asked Agnes dos Santos lash expert, salon owner, and Envious Lashes brand founder of Agnes dos Santos eyelashes london about how to keep your lash extensions in tip-top shape long after you get them done. Keep scrolling for their expert tips on how to take care of eyelash extensions.

Avoid Water for the First 48 Hours

Once your fresh set of extensions are installed, any moisture around the eyes is a no-go. You want the glue to really set in so that your lashes last as long as possible. Feroz tells clients to wash around the eye when cleansing their face and to use an oil-free makeup remover if they have to clean makeup off. To avoid washing the lashes directly within the first 48 hours, keep the eye makeup to a minimum to maximize the extensions.

“Clients should come in mascara-free,” advises Agnes, which makes avoiding washing the eye area much easier afterward.

Skip Oil-Based Products

According to Agnes, oil breaks downs the glue that holds up the lashes, so she encourages clients to avoid oil cleansers and makeup removers. Instead, try a gel-based remover, like the NARS Aqua Infused Makeup Removing Water, to avoid dissolving the glue. Micellar water is also a great option to preserve your extensions’ adhesion and remove debris from them in general.

Avoid Waterproof Eye Products

Waterproof anything won’t come off with just any old face wash—as the name would imply. It usually takes some oil-based cleanser to remove, and we’ve learned that’s a big no-no when it comes to extensions. Both Feroz and Hughes say that you don’t even need mascara or liner when your lash extensions are in; the extensions offer a similar effect to the typical eye-enhancing makeup. (Score one for getting ready faster in the morning.) If you still want to wear a typical eye look, it’s better to go the non-waterproof route so that your eye makeup is easier to remove.

Steer Clear of Mechanical Lash Curlers

We know, we know—our eyelash curler is a holy grail tool in our makeup bags but, with lash extensions, it’s best to lay off the mechanical curler. “You might get a bend that won’t go away,” says Hughes.

If you do end up curling your lashes with an eyelash curler, Agnes recommends the kind that heats your lashes like a miniature curling iron, like the Envious Lashes Heated Lash Curler. “Julia Roberts and Mary J. Blige love it,” she says. It’s hard to argue with that endorsement.

Give Them A Good Brush

No matter how long or where on your body, Hair needs a good detangle every so often. To maintain your fluttery new lashes, make sure to brush them out occasionally. “The rule of thumb is only to brush them out when needed,” says Feroz. Packs of clean spoolies can be found at most drugstores and beauty supply shops.

Thoroughly wash off your mascara wand the next time your tube runs dry, and you’ll have your own person lash comb at the ready—no spending required.

Don’t Pick Or Pull Lashes

As tempting as it may seem, Feroz encourages clients to resist that urge to play with their lashes throughout the day or while cleansing. Not only can fiddling with the extensions pull out the false lashes, but it can also end up damaging your natural lashes. “Touch-ups are required every two to three weeks,” says Agnes. If you don’t have enough extensions left to fill because you were touch-happy, your technician might charge you extra, up to the cost of a brand new set.

Avoid Powerful Showerheads

Agnes warns against ultra-forceful showerheads; the pressure from the water can rip your lashes right out and leave a beauty nightmare scene on the tile floor. Another reason to take it easy while scrubbing up: the steam from hot water temperature can cause freshly-applied glue not to set up properly.

Switch to a Silk or Satin Pillowcase

We’ve all heard how a silk pillowcase can help reduce frizzy hair and face wrinkles, and guess what? Now we can add lash extension preservation to the list of benefits. “Cotton [pillowcases] can cause drying and snagging,” says Agnes, which will lead to premature loss of precious lashes.

Ease Up on the Eye Cream

The reason we love ultra-rich eye creams is the same reason using them with lash extensions isn’t the best idea. All those emollients will have a similar effect on the lash glue as the oil cleansers we mentioned earlier, shortening the lifespan of your faux flutter. Investigate some gel alternatives to eye cream while you have extensions.

Quit Rubbing Your Eyelashes Extension

This is so much easier said than done, but if you’re a chronic eye-rubber, you’ve got to curb your habit if you want to keep on lash extensions. The friction will have them falling like rain, and you’ll likely be out another full set fee way before you planned.

Eyelash Extensions Pros and Cons

As with any beauty treatment, there are pros and cons to consider before deciding if it’s right for you. With lash extensions, the positives and negatives are almost equally weighted, though you’ll rarely hear the downside in a salon that provides this service. Here’s what you need to know to make an informed decision:


They look fabulous. More dramatic than mascara, yet far more natural than a strip of (or individual) false eyelashes, lash extensions are simply stunning when done right.

They’re instantly gratifying. Lash extensions deliver the gorgeous lashes you want with one appointment, and you won’t have to bother applying and removing mascara every day, or worry about mascara flaking, running, or smearing.

They can save you time. Some people say that because lash extensions look just as good if you aren’t wearing makeup, you can forego this time-consuming step in the morning. We’re not convinced about this as you still have to find the time twice a month to get the extensions filled in, so it more or less evens out.

They can last for months and beyond.
Typically, lash extensions stay looking good for 2 to 3 weeks, but beyond that, all of them will gradually fall out on their own. However, with regular fills, your overall lash extensions will last indefinitely.


They’re expensive. Expect to spend anywhere from 150 to 500 (yes, that much) for your first full set of lashes. From there, refills (typically needed every 2–3 weeks) cost 70–150 per visit. If you do the math, that’s anywhere from 1000 to 2500 per year spent on lashes.

They’re high maintenance. Your lashes will need extra attention to look good between fills because preserving these expensive additions to your eyes should be the goal.

Do not use oil-based cleansers and makeup removers as they cause the glue to breakdown.

Avoid using mascara over them because removing it can snag the extensions, causing them to fall out prematurely.

You must be careful when washing your eye area as any movement of your lashes will increase the lash falling out or getting twisted around.

Do not let water from the shower fall directly on your face as the pressure will make the lash extension loosen and shed faster.

Do not rub your face with a towel or press your face too hard into the pillow when you sleep.

Use a dry mascara wand (your lash technician will give you one) at least once a day in the morning or several times during the day, as needed, to comb through your lashes and gently straighten them out, especially if they get wet. Careful! If you tug to much they’ll loosen and fall out. The lash extensions london easily get twisted around from sleeping positions and after washing your face and they can start looking really odd.

Be careful how you apply makeup. Avoid oil-based skin care products around the eyes as well as greasy eye pencils and concealers as they will breakdown the eyelash glue. Also avoid applying heavy eyeliner as removing it tugs at the lashes, resulting in more fallout. Use a cotton swab dipped in makeup remover to take off makeup at your lash line.

The more dramatic the lash, meaning thicker, the more likely it is to get twisted and fall out earlier than you want.
