The words “lash allergy” send a chill down every lash technician’s spine. And for good reason too. Once a client develops one, you effectively lose them, especially if the bulk of your work revolves around lash extensions.
It’s unfortunate, but your clients’ comfort and safety should always be a priority. When one of them calls you crying after a lash appointment because they think they might be allergic, you need to arm yourself with the information to best help them.
What is a lash allergy?
When someone develops an allergic reaction to their lash extensions, the culprit is most often cyanoacrylate, which is the key ingredient in any lash extension glues. It is an irritant for eyes, skin, and the respiratory system. Despite what some companies claim, there are no hypoallergenic glues on the market currently, which means there are no alternatives that could prevent allergies 100%.
Unfortunately, if someone is allergic to this chemical compound, then they will not be able to get lash extensions. What’s more, lash glue allergy isn’t always there. Your client could be just fine one day and end up developing a reaction on their second, third, or even twenty-fifth visit.
Is it a lash allergy or something else?

First of all, you should always direct your client to their doctor for them to be diagnosed properly if they experience any kind of reaction. In the meantime, you should also be familiar with what could be causing them issues.
For example, if it’s allergy season, it may be that they’re just having allergic reactions completely unrelated to their lashes, in response to pollen and other irritants in the air. Another culprit could be a reaction to the glue fumes, or even a chemical burn from the glue due to improperly placed lash pads during application.
