In most cases, Cyanoacrylate (the main component of lash glue) is known to be the substance that causes the glue allergy. You've probably learned that eyelash extension glue cures by its reaction to humidity (to be specific, Cyanoacrylate does)
Only a small percentage of clients develop an allergic reaction to eyelash extension adhesive; this allergy is not especially dangerous. Symptoms will disappear once the eyelash extensions are removed.
You can do things as a lash technician to reduce the potential risk of irritation and allergies. Here are some suggestions on a few things you can do:
Always perform a patch test before the treatment of a new client.
Have a reliable ventilation system in your lash room and keep your lash room clean and your tools sanitized.
Know your products and ingredients of your lash glue. Request lash adhesive MSDS from your retailer.
Only use fresh lash glues. Throw away; glues passed its shelf-life.
The more you know about your client, the more you can reduce possible risks. Ask questions about their past lash extension experiences and her current health conditions.
Use sensitive glue for clients with glue sensitivity.
Place Anti-Allergy Gel by the work station.
Always consult your clients before the appointment.
One of the leading causes of glue allergy that many technicians overlook is the lash client's health condition.
Make sure the safety of your clients is your utmost priority.
Ensure that your clients are well-informed, aware of all the risks before the treatment. There is no certainty that you will never encounter a client with an allergic reaction, so you should familiarize yourself with how to understand the symptoms. This would help you to stay professional and calm in the most critical moments like this!
