Allergic Reactions to Eyelash Extensions

As a lash artist, our utmost priority is the safety and satisfaction of our clients. But occasionally, even with the best products and techniques, some individuals may experience allergic reactions to eyelash extensions.

If you've ever wondered, "How can I fix or prevent allergic reactions from lash extensions?", you're in the right place. Read on to navigate this tricky terrain with ease and ensure a comfortable experience for your clients.

Allergic reactions to lash extensions

Symptoms: Redness, itching, swelling, or discomfort around the eyes.

How to Fix:

  • First and foremost, if your client experiences severe symptoms, they should seek medical attention immediately.
  • For mild reactions, you can recommend an over-the-counter antihistamine (after confirming it with a healthcare professional).
  • Gently remove the lashes if the client is experiencing discomfort.



  • Conduct a patch test 24-48 hours before a full set application.
  • Ensure your workspace is clean and sanitized to reduce the risk of irritation.

Lash Extensions Falling Out

Is it normal for some lash extensions to fall out straight away?

Yes, it's normal for a few lashes to fall out immediately or within the first couple of days due to the natural lash cycle. However, if a significant number are falling out, it's time to reassess your application technique or the products you're using.

What causes lash extensions to fall out?

  • Natural Lash Cycle: It's natural for lashes to shed and regenerate. Lash extensions attached to lashes at the end of their lifecycle will fall out sooner.
  • Improper Aftercare: Oils or glycol-based products can break down the adhesive, causing early fallouts. Make sure your clients are aware of proper aftercare.
  • Faulty Application: Too much or too little adhesive can affect the longevity of lash extensions.


Why do lash extensions fall out faster on one eye?

This can happen for several reasons:

  • Sleeping Habits: Sleeping on one side can cause more pressure and friction on lashes, leading to premature fallouts on that side.
  • Differences in Natural Lashes: One eye might have lashes that are in a different phase of the growth cycle compared to the other.
  • Inconsistent Application: Ensure that the adhesive is applied evenly and consistently on both eyes.
