What are the dangers of eyelash extensions that most people don't know about?

Don't ignore the quality of the glue and materials used in the salon. Cheap formaldehyde-based adhesive can cause not only allergies but also gradual weakening of your natural lashes - they become brittle and thin. A lot of girls think that once the extensions are removed, everything will recover, but if you do this procedure frequently without breaks, your natural lashes might simply not grow back properly. The follicles get depleted, and even after half a year or a year, your lashes remain sparse.

Another thing that's rarely talked about is the pressure and tension. When a technician glues artificial hairs too close to your eyelid skin or pulls them too tight, blepharitis or a chalazion can develop. It's not critical, but it's uncomfortable and requires treatment. Plus, if you get extensions done very often without taking monthly breaks, you might start having issues with eye sensitivity and tearing.

My advice: choose reputable salons that use quality glue (hypoallergenic), and definitely take breaks between procedures of at least a month or two. If you notice your lashes starting to fall out, your eyes getting red, or constant tearing - that's a signal to stop and give your eyelids a rest.
