Nobody Likes Allergies - Let's Treat Them

Nobody Likes Allergies - Let's Treat Them

Lash allergies get worse with more exposure to the adhesive.  This can make identifying an allergy a little bit tricky, because the first reaction may be mild and mirror an irritation.  On the other hand, it can also be a gentle lead to identifying an allergy and putting a stop to lash application long before the allergy gets out of hand.  There are many times, however, that an allergy goes unnoticed and develops into something extreme.*

These situations can be pretty miserable and clients will obviously call their lash artist for immediate help! What do you do?!

First and foremost, stay calm.  Gaining a little bit of knowledge and understanding eyelash extension allergies will help you best care for your clients and keep them comfortable.


  1. Have them take a Benadryl to help alleviate some of the swelling and itchiness.
  2. Remove the client’s lashes as soon as possible.
  3. In the meantime, tell your client to use a saline or sterilized foam wash (specifically designed for lashes and eyelids).  Both of these will help cool the eyelids and make them feel more comfortable.
  4. Tell them to go to a doctor if swelling and symptoms persist after 48 hours of removing lashes. The doctor will ask to see the MSDS for the adhesive to know what ingredients are in the adhesive.  It’s best practice to either have this on hand or know what ingredients are in the professional lash adhesive. Remember, typically clients are allergic to cyanoacrylate in the adhesive - tell the doctor that.

After allergies have developed, lash artists should discontinue applying lashes on those clients.  The most important thing you can do as a lash artist is to stay educated.  This will help you remain calm and best know how to help your clients. Let me know if you have any other questions.

  • I am a lash extensionist and get severe asthma like allergies after working with my clients. I am afraid that I will have to quit offering this service. Any suggestions on how to deal with this? Have you heard of extensionist with the same problem?

  • Enjoyed reading this one only because nothing is more frustrating then having a client you love, have a reaction after having them on for more than 6 months! I know there’s not a lot you can do if a client has a reaction to the cyanoacrylate but are there any other tricks to possibly avoid it to happen at all or perhaps give me tips to minimize this from happening?
    Thanks xo,

  • Hi Jessica,
    Thanks for your comments. This is a common occurrence for some girls. My guess is that that burning sensation stops after a couple of days. The best explanation is that all of the cyanoacrylate in the adhesive isn’t cured yet. Since it cures when exposed to water we use a nano mister to assist. If the adhesive is thick or applied too fast for all the layers to dry properly than the water from the shower can “shock” the adhesive to dry and lets off fumes which can cause a burning sensation. The best thing you can do as a lash artist is to make sure you are applying the minimal amount of adhesive as possible. Even when you are doing this some girls will still have really sensitive eyes, but there is not worries of allergies or safety concern with that. Hope that helps. Let me know if you have any other questions.

  • Hi Megan- I have a client that does not have irritation with the lash extensions other than when they are exposed to water. She says her eyes ‘burn’ when wet(submerged or even just splashed with water). Help!

    Thank you,
