Lashes and allergic reactions, what you need to know.
"Can I Get Lash Extensions Again After a Reaction?" What You Need to Know
If you’ve ever experienced eye irritation—or worse, a reaction—after getting lash extensions, you're probably wondering: Is it safe to try again? Or what if it happens again—do I have to give up lashes forever?
Short answer: Sometimes you can still wear lash extensions—even after a reaction. But it really depends on what kind of reaction you had and how your body responds going forward.
Allergy vs. Irritation: Know the Difference
What many clients think is an allergic reaction often turns out to be eye sensitivity or irritation. Here's how to tell the difference:
Sensitized Eyes
This usually looks like red, dry, or slightly irritated eyeballs—not the eyelids themselves. It’s typically caused by dryness during your lash appointment (especially if your eyes were slightly open during application). In most cases, some saline drops and rest will do the trick—but always consult your doctor first.True Allergic Reaction
This is far more intense. You’ll know if it’s happening. The lash line and eyelids become very swollen, crusty, and often itchy. This isn’t something to brush off or self-diagnose.
What To Do If You Have a True Allergic Reaction
According to an ophthalmology surgeon who spoke at LashCon 2019, here’s the protocol:
Seek medical attention—contact your primary care doctor, an ophthalmologist, or go to urgent care.
Tell your doctor two key things:
“My lash artist informed me to seek medical attention for Allergic Contact Dermatitis from a recent lash extension application.”
“I may need a prescription for topical dexamethasone ointment. This was suggested by an ophthalmology surgeon, and I understand it’s a steroid intended for short-term use only.”
In the meantime, wash your lashes and lids thoroughly with the cleanser provided by your artist. This helps remove lingering adhesive fumes that may still be irritating the skin. Once you get the ointment, apply it sparingly along the upper lash line like eyeliner—it usually only takes a couple of days to calm things down.
And just to clarify: once the adhesive cures, it becomes a plastic polymer—it’s no longer producing fumes. So removing your extensions (which requires additional chemicals) often causes more irritation. In most cases, it’s better to treat and wait it out.
So… Can You Get Extensions Again?
If you’ve had a reaction before, but still want to enjoy lashes, here are a few options to explore:
Patch testing with low-cyanoacrylate or sensitive adhesives
Short-term wear (like for a special event or weekend)
Topical dexamethasone before or after application (with doctor approval)
Excellent lid hygiene before and after every appointment
Working with a skilled, licensed artist who knows when to refer out
It’s worth repeating: dexamethasone is not a cure. It simply reduces inflammation and the immune response short term. It’s not a long-term solution, and it’s definitely not for everyone.
Your Health Comes First
At the end of the day, lash extensions should enhance your natural beauty—not compromise your comfort or safety. That’s why I maintain an ongoing relationship with a local optometrist and follow all industry best practices. I also believe in educating my clients, so you always feel confident and cared for.
