Yes - eyelash extensions are safe when done correctly. It is a common misconception that eyelash extensions are bad for you because they damage your natural lashes. Eyelash extensions do not damage your natural lashes if they are applied correctly. This means individually isolated and minimal glue usage at the base of the natural lash at least 0.5mm-1mm away from the eyelid.
This is why it is important to do your research before getting your eyelashes done. Make sure you go somewhere that is highly experienced. Be sure to maintain the proper aftercare too such as avoiding rubbing your eyes or pulling at your extensions after your treatment.
Since your eyes are closed for the whole duration of the treatment, glue cannot accidentally get in your eye. If you feel a stinging or burning sensation during your treatment, this is usually from the fumes of the glue or the eye patch being placed too close to the waterline. Just make sure you let your lash technician know so that they can use a fan or air blower to get rid of the fumes.
Most people won’t notice their natural lashes shedding because our natural lashes are so small and fine. However, you will find that with eyelash extensions, you are more likely to notice them as they’re a lot more noticeable in length and thickness.
