If you’ve been wondering if your favorite pair of fake lashes will ruin your real ones, you’re in the right place.

  • Fake lashes may cause a bit of damage to the natural lashes, but it’s rare. Usually, the damage is caused by incorrect usage. The lash fall is usually reversible.
  • Lash extensions are more likely to have harmful effects on lashes and eyes. These are usually a result of allergies or of poor training.

Will Fake Lashes Damage Real Lashes? 

False eyelashes are incredibly popular. They’re a temporary eyelash enhancement that sticks to the lash line with latex or acrylate-based adhesive. But can fake lashes ruin your real ones? 

The good news is that false lashes, when used properly, won’t damage your eyelashes at all! It’s only when you over-apply glue or pull the lashes off aggressively, that some lashes may get caught and pulled out. 

Never pull your lashes off when it’s time to remove them. Instead, peel them off gently with the help of makeup remover and a cotton swab.

As long as you don’t use too much adhesive, your natural lashes will remain perfectly intact. If you use falsies instead of mascara, they might even help keep your lashes healthier! 

Some sources theorize that the weight of the falsies over your real lashes may have repercussions. But it’s a theory, and as many avid falsie-wearers will attest (especially the ones using our Natural Lashes), it doesn’t seem to be a real issue. 

Will Lash Extensions Ruin Real Lashes?

As any eyelash technician will tell you, one of the most frequent questions they hear is whether extensions damage real lashes. The answer, depending on who you ask, is either “it depends” or “maybe.” 

Eyelash loss is most likely to occur during incorrect removal. If you attempt to remove your extensions by yourself, the risk of pulling on your natural lashes is higher, and you’re likely to lose quite a few. 

There hasn’t been any research on the impact of eyelash extensions on natural lashes. Some technicians hypothesize that after removal, the lashes seem more sparse because the client has gotten used to the voluminous extensions. Once the extensions are gone, the difference can seem stark. 

There are some theories behind how extensions could potentially damage lashes, but they’re not proven. It’s possible that the weight of the extensions puts stress on the lashes and temporarily inhibits their growth, especially with voluminous styles. It’s also possible that oil and debris buildup from improper cleaning can damage the hair follicle. Whether these issues are significant enough to cause lash fall is entirely unknown. 

The good news is that even if the extensions slightly damage your lashes, they will grow back. Human eyelashes go through a regular growth cycle. If you feel like you lost more lashes than normal, they’ll replace themselves within a few months.  

The only long-term risk to your lashes comes if you experience a skin allergy or infection. This can damage your follicles, and inhibit your lash growth in the future.  We discuss this in more detail below. 

Other Risks Associated With Different Types of Eyelashes

There are a few more risks to consider when it comes to falsies and eyelash extensions. 

False Eyelashes

As with most eye makeup products, there are some health risks associated with wearing false eyelashes. These risks are usually pretty easy to mitigate with a bit of research and good hygiene! 

The two main risks from using falsies are allergic reactions and infection. Allergies are usually caused by lash adhesives, especially when they’re made of latex. It’s also possible to be allergic to latex-free glues, although it’s less common.

Allergies tend to appear as mild irritation along the lash line, although it’s also possible to experience more severe reactions. 

Finally, if you borrow a friend’s lashes, or fail to clean your falsies thoroughly between uses, you’ll be at risk of an eye infection. This can have long-term repercussions on your eye health. 

Eyelash Extensions

Eyelash extensions pose slightly more risk than false eyelashes. Because they’re a little riskier, it’s not surprising that they can only be done by highly-trained professionals. 

The most common risk of eyelash extensions is an allergic reaction to the glue, which contains cyanoacrylate. This kind of reaction is usually mild, but in severe cases, it can lead to significant pain, redness, and swelling. It may even cause severe eye or skin issues, so consider doing a patch test with the adhesive before getting extensions done. 

However, allergies are unpredictable. You may not have any reaction the first few times you get extensions, despite being allergic. You’re more likely to experience a reaction if the glue comes in contact with your skin. This is pretty rare, especially if your lash technician is very experienced. 

Commercial lash adhesives, including the one produced by Lilac St., are made with gentler adhesives so they are slightly less likely to aggravate allergies. 

There is also a risk of eye infection, especially if you go to a disreputable salon that doesn’t practice good hygiene. 

Prevention Tips

If you want to keep your natural lashes looking fabulous, here are our tips for both falsies and eyelash extensions. 

False Lashes 

  • Always patch test new lash glue on your forearm or behind your ear for a few days. 
  • Consider avoiding latex-based adhesives if you have sensitive skin.
  • Never pull your lashes off at the end of the night. Instead, peel them off gently with the help of makeup remover and a cotton swab. 
  • In between uses, disinfect your false lashes with alcohol.
  • To keep your lashes intact, skip the mascara when wearing falsies. 


  • Spend your time researching and reading reviews, to make sure you choose a reputable lash technician or salon. 
  • Book a consultation a few days before, and ask to patch test the extension adhesive. 
  • Your first time, opt for a lightweight, classic look that won’t weigh your lashes down.
  • Follow the aftercare instructions given by your lash technician, and keep your extensions clean and groomed and make them last longer
  • Never try to remove extensions at home. Always go back to your lash technician for proper lash extension removal. 
  • Take a break from lash extensions for a few weeks if you feel like your natural lashes are starting to look sparse.  

To Healthy Lashes

Both eyelash extensions and false lashes are pretty safe, even if they’re not fool-proof. Making sure that your fake lashes don’t ruin your real ones requires a bit of time and research. However, as long as you pay close attention to hygiene and potential allergies, we think your lashes will be just fine. Here’s to healthy, gorgeous lashes!
