Eyelash Extensions Do’s

Do Go To A Certified Lash Artist

One of the first things to ensure when getting a lash treatment is to make sure you consult a certified professional. Lash technicians have been trained to apply lash extensions in a secure manner with the health of your natural lashes in mind.

To prevent infection, your technician will use sterile tools on you and after the process is finished; it must be rinsed with disinfectant so it’s not an option to get these extensions done by yourself.

Each state in the U.S. will have their own requirements before someone is allowed to apply eyelash extensions but most states require a licensed technician. For instance, South Dakota requires a license and a minimum of 16 hours of training,[1]

If you have concerns about the technician’s credentials, ask to see their certification and registration. Most salons will gladly oblige to show you the certificate.

Do Ask For An Allergy Test

Some clients may experience an allergic reaction to the eyelash extensions. Your stylist can perform a patch test before the actual appointment to determine if you are allergic or not.

If you experience any discomfort when wearing eyelash extensions, make sure you contact your technician right away. In most cases, it is usually an allergic reaction to the adhesives used in the process. Your technician can give you some possible options, but most of the time you may need to remove the extensions.

Do Wait Four Hours Before Getting Your Lashes Wet

The curing period for lash adhesive is four hours nowadays although it was over 24 hours not too long ago. Lash adhesives have improved significantly over the years.

It’s crucial you don’t let extensions get wet or heated up during this interval. Once the glue is cured, you can get it as wet as you want.

Do Clean Your Lashes Regularly

Our eyes blink to remove the secretions of the eye but it’s quite unnoticeable during the day. When you don’t blink during sleep, this mucus can pile up and create rheum or eye gunk.[2]

If you don’t clean your eyelashes properly after waking up, the gunk can crust up and block your lash follicles and their oil passages. It can prevent natural lashes from growing and eventually lead to lash mites.

That’s why you should wash your eyelashes with a safe cleanser after working out, swimming, bathing, and cleaning every day.

Do Brush Your Eyelashes

It’s common for lash extensions to tangle or mess up after a long or windy day. That’s why you must always keep a spoolie or mascara wand with you. Doing so prevents natural lashes from growing in the wrong direction as well as preventing stress on your lashes.

Do Sleep On A Silk Pillowcase

Do you know cotton is known to grab onto your hair and twist it from the roots?[3] It can absorb the oils and leave your lashes dry and brittle which makes them susceptible to break easily. The best way to resolve this problem is by avoiding abrasive materials and getting a pillowcase made with friction-free material like silk.

Do Let Your Lashes Air Dry

There are three ways you can dry your lash extensions:
1- Air-dry
2- Blow dryer but avoid holding it too close to your natural lashes as this may damage your extensions. Moreover, you should use the cool air setting and the low air pressure.
3- Tapping very gently with a tower the bottom of your lash line.

Do Protect Your Lashes From Heat

Another thing that wears down the retention of your lash extensions is heat. Excess sunlight exposure can dry your lashes and break them or cause them to fall out.[4]

You should avoid going out in extreme heat or wear sunglasses to prevent lash extensions from heating up when doing so. One thing popular with most of my clientele is polarized glasses and I agree they are good at keeping your lashes cool on a scorching day.

Do Understand Lash Treatment Isn’t Quick

An eyelash appointment will last 90 to 120 minutes for a full set as each and every lash needs to be isolated from the others. For quality results, you need to give yourself enough time.

Refills take 30 to 60 minutes for classic lashes.

Do Ask Questions To Your Lash Tech

If there’s anything irritating you with the new lash extensions, don’t hesitate to consult the lash tech who did the treatment. On a general note, it’s good to know how long your extensions will last and what you need to do for aftercare from your lash tech too.

Don’t Wear Eye Makeup To The Appointment

When you go to the salon with your eye makeup on, the lash tech will ask you to remove it before the appointment can start. You will loose some time that was allocated for your appointment. Walking into the salon without any makeup so that the lash artist can cleanse and prime your lashes easily is the best way to go.

Don’t Sleep On Your Stomach

Sleeping etiquette while wearing lash extensions is a critical factor that decides the longevity of your lash extensions. Instead of sleeping on your stomach that squishes your lashes, sleep on your back. Read more on how to sleep with your lash extensions here.

Don’t Go For Hot Treatments

As we already know heat is detrimental to lash extensions, it’s good to avoid hot treatments like steam baths, saunas, or even artificial tanning when wearing extensions. That being said, short intervals of steam and sauna aren’t a threat but prolonged exposure is.

Don’t Rub Your Eyes

Rubbing your eyes harshly with your hands isn’t good for eyelash extensions as you can accidentally pull them out during the process. Avoid using your hands or towels to rub the eyes when wearing lash extensions.

Don’t Use Abrasive Materials To Clean Lashes

Anything abrasive like cotton pads or wipes isn’t good to clean eyelashes when wearing fake eyelashes. Instead, find lint-free makeup remover pads to do the job.

Don’t Let Hair Products Seep Onto Lashes

When you’re bathing, take care to use oil-free products. Alternatively, make sure hair oil, shampoos, and conditioners don’t roll down onto your lashes during the bath.

Don’t Use A Lash Curler

As eyelash extensions come with preset curls in grades such as J, L, B, C, D, M, U, etcetera, you don’t need to re-curl synthetic eyelash extensions. However, if you’re wearing mink or other natural lash fibers, fake lashes most probably will lose the preset curl after getting wet. Take a look at our detailed article on whether you can curl eyelash extensions to know more about it.

Don’t Get Cheap Lash Extensions

Cheap eyelash extension services should raise a red flag in your mind. These cheap services usually use low quality adhesives and low quality lashes.

Just like any other service, quality has a price. The eye area is especially sensitive and this is why you should never compromise on quality.

For instance, I have once received a client from another salon that had cluster lashes applied to her lashes! Cluster lashes refer to several eyelash extensions that are glued together by the manufacturer. They are cheaper than extensions and are also popular as pre-made or pro-made lashes.

Because these already have glue on, the total glue at the root the lash tech has to apply onto extensions goes overboard and ends up weighing down on your natural eyelashes. This can easily damage your natural lashes.

Make sure you pay the right amount (not too much, not too little) to get quality extensions that will avoid damaging your natural lashes.

Don’t Use Facial Products With Oil In Them

Oil-based products are a big no-no for eyelash extension wearers because oil can disintegrate lash glue. Moreover, oil is difficult to clean up and the same might require you to rub around your eyelashes harshly to get it all out.

Don’t Use Eye Products With Conflicting Ingredients

There are many chemicals like oil that damage the bond created by lash glue too. You should watch out for common cosmetic ingredients like PEG (Polyethylene Glycol), Hexylene Glycol, Butylene, and Propylene Glycol to be on the safe side.[5]

Don’t Get Lash Extensions If You Have Certain Diseases

People of all ages can get eyelash extensions but those with certain medical conditions like Alopecia Areata, Eyelid Dermatitis, Trichotillomania, and Blepharitis mustn’t.[6] Even if you have a wound or broken skin around your eyelashes, wait for the lash treatment until you’re healed.

Don’t Pull Out Lash Extensions On Your Own

Lash extensions are applied with the use of glue that contains the same thing as superglue. That’s why you shouldn’t attempt to remove it on your own. Always go back to your lash tech to get it done. If you’re interested, here’s an article on removing eyelash extensions at home to read more on.

Don’t Swim In Saltwater For A Long Time

Salt is another thing that breaks down lash glue. Hence, don’t soak in saltwater such as swimming in the ocean for prolonged hours. If you need to, wearing goggles that don’t squish your lashes are recommended for added protection when in contact with saltwater.

Don’t Let Be Careless When Showering

You need to make sure to avoid hot or cold water from falling on your eyelash extensions at high pressure while showering with eyelash extensions. That’s because high-pressure water can break down the lash glue irreparably.

Don’t Get A Treatment On Your Extensions

Lash extensions are designed to make your natural lashes appear fluffy, lifted, or as good as the style you choose. Moreover, they don’t fare well with chemical treatments like a lash lift or perm. That’s why you mustn’t get these treatments while wearing extensions. If you must, get a lash lift or perm before getting eyelash extensions.

Don’t Cut Your Lash Extensions

Sometimes the new lash extensions style you got might look great at the salon but not at your dressing table. In such a case, don’t go ahead and repair it on your own. Cutting or shaping them on your own is very risky for your eyes. Instead, go to the same lash salon you went for treatment so that your tech can adjust the lengths per your requests.

Don’t Open Your Eyes During The Appointment

Once the lash tech has placed gel pads under your lower brows, it’s not advisable to open your eyes until you’re advised during application. That’s because opening your eyes mid-treatment can cause the lash glue to leech into sensitive parts of your eye and cause reactions.

Don’t Wait Too Long For A Refill Appointment

While it’s true that last extensions are a costly commitment, it’s not a good choice to delay the refill appointment. You might want to extend a couple of weeks but by then all your extensions may have fallen out and you might need a full set again.

Here’s an article citing how many times clients go for a refill based on over a thousand clients we have had.

Don’t Use Waterproff Makeup Products

Makeup products like waterproof mascara or eyeliners often turn out to be a hassle when removing. Moreover, you will end up having to use harsh removers or pads to scrub them all out at the end of the day.

Final Thoughts

Eyelash extensions require a budget and that’s why you might feel inclined to make them last as long as you can. But the truth is eyelash extensions are shed with your natural lashes. But with the above list of dos and don’ts, you can extend their lifespan.

As for aftercare, cleaning and brushing lashes must be a daily routine on top of following a good sleeping etiquette without squashing your extensions.

The treatment itself is typically a 90 to 120 minutes appointment and you must clear your doubts with the lash tech before or after the treatment. Take care not to rub your lashes with hands or towels or using tools like lash curlers, waterproof mascaras, and oil-based cosmetics. You must also avoid heat and salt to make extensions last longer and stay intact.

Finally, don’t cut extensions on your own. If you feel like getting them off, go back to the salon you got them at so that the lash tech can safely do so. Remember to go for a refill every three to four weeks and you’ll fall out of love with lash extensions.
